The PinePhone Pro is PINE64’s flagship smartphone announced on October 15, 2021. It features 4GB of RAM, an 128GB eMMC and is using an Rockchip RK3399S SoC, which is a specialized version of the RK3399 made specifically for the PinePhone Pro.

Introduction

The PinePhone Pro is PINE64’s second smartphone and a successor to the original PinePhone. It does not, however, replace the original PinePhone. It should also not be considered a second generation PinePhone; it is a higher-end device, with much better specs, aimed at those who wish to daily-drive a open system stack. Achieving this goal will, however, take time as the software and overall smartphone software ecosystem needs to mature.

Editions and revisions

Similarly to the original PinePhone, various PinePhone Pro editions are planned, the first of which is the Developer Edition (aimed at developers, as the name entails) followed by the Explorer Edition, which is aimed at early adopters.

• Developer Edition
• Explorer Edition

Help and support

Still have any questions regarding software, shipping, or ordering after reading the documentation? Please don’t hesitate to contact the community in the bridged community channels for detailed answers or simply to chat with friendly people in the community! See Main Page.

Please keep in mind that PINE64 is not like a regular company (see the PINE64 philosophy) and that support resources are limited - the best way to get support quickly is to ask in the community chat! Please only contact the PINE64 support directly if questions couldn’t be solved via the community chat or the documentation.

First time setup

When shipped the battery is isolated from the device using a protective plastic tab, which is required to be removed before using the phone. The battery will not charge or boot until it is removed and the battery is connected again.

The SIM card has to be placed in the lower slot, while the microSD has to be placed in the upper slot. Devices shipped after the end of July 2022 do only accept a nano-SIM, the SIM is inserted into a carriage released by slightly pulling on the handle in the lower slot (for information regarding devices shipped prior to end of July 2022 see below).

Software

Boot order

The RK3399S processor in the PinePhone Pro searches for the bootloader (such as U-Boot or Tow-Boot) in the following order:

1. SPI flash
2. eMMC (the internal memory)
3. MicroSD card

Boot from microSD card temporarily

To temporarily boot from an inserted microSD card do the following:

• On the Explorer Edition ordered after November 2023 the microSD card is first in boot order due to using rk2aw instead of Tow-Boot, see here. A boot menu can be opened by holding power at boot for not too long.
• On the Explorer Edition ordered after July 2022 hold the volume down key while powering on the device. The batches bought after July 2022 come with Tow-Boot flashed to the SPI, which offers additional functionality over U-Boot as bootloader.
• On the Explorer Edition ordered between January and July 2022 hold the RE button underneath the cover for a few seconds, while powering on the device. If the button is labeled RESET instead of RE please verify if the device is a regular PinePhone (or the Developer Edition). This is required because older batches don’t ship with Tow-Boot on the SPI. Flashing Tow-Boot can be caught up by following this instruction. Note: If Tow-Boot is flashed later, the microSD card can be selected at boot with the volume down key as well.
• On the Developer Edition (sold to selected developers only) the SPI and the eMMC can be bypassed by shorting the bypass test points while booting. The process is explained in the article PinePhone Pro Developer Edition. Please join the community chat for any questions regarding the process.

The RE button disables the SPI and the eMMC at the hardware level while the button is held and the PinePhone Pro will try to boot from the next available boot medium, which is the microSD card. Note: When holding the RE button (or when shorting the contact points in case of the Developer Edition) for a longer time at boot the operating system will not initialize the SPI and eMMC and it will not be possible to write to these storage mediums until the next reboot.

Boot from microSD card permanently

The bootloader (such as U-Boot) resides in the free space in front of the first partition. Wiping the bootloader from the eMMC to make the PinePhone Pro boot from microSD card can be done using sudo dd if=/dev/zero of=/dev/mmcblk2 seek=64 count=400 conv=fsync. Formatting the drive or deleting the partition table is not sufficient to wipe the bootloader.

Installation instructions

The software releases can be installed (the process is being referred to as flashing) to the internal memory of the PinePhone Pro (the eMMC) or to an microSD card.

Installation to the microSD card

The images can be installed to an microSD card and be booted from it.

To install an image to the microSD card:

1. Download a compatible image from Releases.
2. Important: Typically the image will be compressed in an archive file to reduce the download size (such as .gz or .xz). Extract the image from its archive file to get the file with the file extension .img.
3. Write the image to your microSD card using your favorite method, examples:
   • Using dd: On the device you’re flashing the microSD card from, find the correct device under lsblk and then flash the image to the microSD card using sudo dd if=IMAGE.img of=/dev/[DEVICE] bs=1M status=progress conv=fsync and make sure the target is the whole microSD card and not its first partition, sdc1 or mmcblk0p1 are wrong!
   • Using bmaptool: Make sure to select the correct device using lsblk. Then run bmaptool with the correct device: Download the IMAGE.xz and the IMAGE.bmap files, then run bmaptool copy --bmap IMAGE.bmap IMAGE.xz /dev/[DEVICE]. This takes around 2.5 minutes to flash a 4 GB file.
   • Using a graphical tool: A graphical tool such as Gnome Disks under Linux or Etcher under Windows may also be used.
4. Insert the microSD card into the top slot of the PinePhone Pro
5. Boot the device using the following method:
   • With rk2aw (as on the Explorer Edition ordered after November 2023): boot the phone without any further action if the image includes a bootloader or one is installed to the eMMC (such as in the default installation).
   • With Tow-Boot (as on the Explorer Edition ordered after July 2022): hold the volume down key while booting.
   • With an empty SPI (like on the Explorer Edition ordered between January and July 2022): hold the RE button underneath the back cover while booting (or use the volume down key if you flashed Tow-Boot).
   • On the Developer Edition (sold to selected developers only) there is no RE button. Instead apply the bypass by shorting the testing pads while booting according to the datasheet.

Installation to the eMMC

Installing an operating system to the eMMC (the internal memory of the PinePhone Pro) can either be done by booting an operating system from the microSD and by installing to the eMMC directly from the booted microSD card operating system (recommended) or by using Tow-Boot’s USB Mass Storage mode.

By booting a microSD card

The eMMC can be overwritten by booting an image from the microSD card and overwriting the eMMC from within that booted microSD card image.

This installation method is recommended.

1. Boot an operating system from the microSD card. If there is already a bootloader on the eMMC installed see the section Boot order to bypass it.
2. Download or copy the desired image to the microSD card as file
3. Check if the eMMC appears under lsblk. If it doesn’t appear in the output of the command, the eMMC wasn’t initialized due to applying the above explained bypass method for a too long time during the boot
4. Important: Typically the image will be compressed in an archive file to reduce the download size (such as .gz or .xz). Extract the image from its archive file to get the file with the file extension .img.
5. Flash the image file using sudo dd if=IMAGE.img of=/dev/mmcblk2 bs=1M status=progress conv=fsync (replace IMAGE.img with the filename of the image you want to flash and make sure it has the file extension .img).
6. Reboot the PinePhone Pro

By using Tow-Boot

The image can be written to the eMMC by using Tow-Boot’s USB Mass Storage mode.

This installation method is not recommended, as the USB connection can be unreliable and in some cases not work at all.

1. Pre-requirement: Tow-Boot must be installed on the SPI, eMMC or the microSD card
2. Power off the device
3. Power on the device and hold the volume up key before and during the second vibration
4. The LED will turn blue if done successfully. This will only work if Tow-Boot is installed
5. When connecting the device to a computer via USB it will behave like an USB drive now
6. Check if the eMMC appears under lsblk, the output might look like the following:
   mmcblk2 179:0 0 115.2G 0 disk
├─mmcblk2p1 179:1 0 122M 0 part /boot
└─mmcblk2p2 179:2 0 115.1G 0 part /
   Note: In this example, /dev/mmcblk2 is the device, while mmcblk2p1 and mmcblk2p2 are partitions of the device. The downloaded images are images from full devices, which means that the full device (mmcblk2 in this example) needs to be flashed. Ignore the partitions!
7. Important: Typically the image will be compressed in an archive file to reduce the download size (such as .gz or .xz). Extract the image from its archive file to get the file with the file extension .img
8. Flash the image file using sudo dd if=IMAGE.img of=/dev/DEVICE bs=1M status=progress conv=fsync (replace IMAGE.img with the filename of the image you want to flash and make sure it has the file extension .img and replace DEVICE with the correct device from the lsblk command)
9. Reboot the PinePhone Pro

Software State

Bootloaders

The following section contains notes regarding compatible bootloaders with the PinePhone Pro.

rk2aw

The rk2aw loader program is designed for modern Rockchip SoCs. It modifies the boot ROM bootloader load order from the original and rigid “SPI NOR flash -> eMMC -> SD card” to a more flexible “SD card -> eMMC -> SPI NOR flash”. Additionally, it enables robust A/B bootloader updates in SPI NOR flash, allowing users to choose fallback options via a pre-boot menu. For details see the rk2aw page.

U-Boot

U-Boot is an open-source bootloader commonly used in embedded operating systems and is often pre-installed on device images.

Tow-Boot

Tow-Boot is an opinionated distribution of U-Boot and brings numerous advantages over stock U-Boot, such as the possibility to choose from booting the eMMC or microSD card using the volume buttons during boot, as well as a USB Mass Storage mode, where the device can be written to by connecting the device to a computer via USB.

The user can flash Tow-Boot to the PinePhone Pro using the instructions on the Tow-Boot website.

levinboot

The levinboot bootloader is another option for the PinePhone Pro. The project repository can be found here. (Pinephone Pro supporting fork is here.)

Multi-distribution image

This article explains how to install a multiple linux distribution environment on your PinePhone Pro. You can choose to install this environment to the phone’s internal eMMC memory or to a microSD card. These instructions also integrate with the multi-distribution image releases page section.

Variables

During the processes of partitioning the target device, building the image or installing the bootloader, make sure the variables are properly defined. Each time you open a new terminal window, the values of the variables must be re-set.

💡 TIP

BASE is the base directory path on your computer
DEV is the device name from the lsblk command
ATTR are the attributes of each partition/distribution
SIZE is the GiB capacity of each partition/distribution
NameUrl is the Key:Value of distribution name and relative URL download address

This guide has been tested with 6 Linux distributions on a 128 GiB microSD card, and following variables:

$ BASE=ppp-multi-image
$ DEV=sdb # i.e. sdb or mmcblk0
$ ATTR=RequiredPartition,LegacyBIOSBootable
$ SIZE=11GiB

$ declare -A NameUrl
$ NameUrl[uboot]=https://xff.cz/kernels/bootloaders-2024.04/ppp.tar.gz

Install rk2aw

Make sure your phone has the rk2aw pre-loader installed to its SPI flash memory. PinePhone Pro models ordered after November 2023 are shipped with rk2aw pre-installed. Otherwise, follow the instructions in this section to install it.

Boot up the PinePhone Pro’s stock operating system and start a shell session. You can do this either by opening the terminal emulator app, or by enabling the SSH service and logging in from a PC on the same network. Then execute the following commands (from the phone’s shell):

$ curl -O https://xff.cz/kernels/bootloaders-2024.04/ppp.tar.gz
$ tar -xvzf ppp.tar.gz
$ cd ppp
$ sudo ./spinor-flash-initial-setup.sh

💡 TIP

The multi-boot image can function without rk2aw, but you will need to make sure the correct bootloader is started by your phone’s SoC.

If you are installing to a microSD card, then either:

1. Ensure that the phone’s SPI flash and eMMC are empty, or
2. Hold down the RE button during boot to force the phone to boot from the microSD card by disabling the SPI flash and the eMMC.

If you are installing to the eMMC, make sure the SPI flash is empty.

Further instructions can be found on the author’s website.

Expose the device

Connect your PinePhone Pro to a Linux computer, with the stock USB cable. Press power button on. From the graphical menu select eMMC over USB or SD over USB to expose the device to your computer. You can optionally flash microSD directly into your computer’s slot, if available.

Erasing

Make sure there are no signatures or partitions left, and overwrite the first sectors with zeroes. You can find the target device under lsblk command.

$ sudo wipefs /dev/$DEV
$ sudo wipefs --all --force /dev/$DEV*
$ sudo dd if=/dev/zero of=/dev/$DEV status=progress bs=32768 count=1

Optionally you can zeroes the whole device:

$ sudo dd if=/dev/zero of=/dev/$DEV status=progress bs=32768 count=$(expr $(lsblk -bno SIZE /dev/$DEV | head -1) \/ 32768)

Partitioning

Partition the device for the multiple distributions:

$ sudo sfdisk /dev/$DEV --wipe always <<EOF
label: gpt
first-lba: 64
table-length: 10
attrs=RequiredPartition, type=D7B1F817-AA75-2F4F-830D-84818A145370, start=64, size=32704 name="uboot_raw"
$(
for name in "${!NameUrl[@]}"; do
  case ${name} in (uboot|extra) continue ;; esac

done | sort
)
attrs="$ATTR", size=$SIZE, name="$BASE-ut-data"
attrs="$ATTR", size=+, name="extra"

Install U-Boot

In order to display the graphical distribution selector when the phone boots, we need to install a custom version of the U-Boot bootloader.

First, use the following commands to download the required U-Boot image. Note that we are downloading the same ppp.tar.gz archive as we did in the rk2aw section; if you already have a copy of this archive on your computer, you may skip the download and simply extract its contents into ~/$BASE/downloads/.

$ NAME=uboot
$ mkdir -p ~/$BASE/downloads && cd ~/$BASE/downloads
$ wget ${NameUrl[$NAME]}
$ tar -xvzf $(basename "${NameUrl[$NAME]}")

Then, use the following command to install the U-Boot image to the correct location on the microSD/eMMC:

$ sudo dd if=ppp/foss/u-boot-rockchip.bin of=/dev/$DEV bs=512 seek=64 status=progress conv=fsync

💡 TIP

If you are interested in building this U-Boot image yourself, you can download the source code from xff.cz. However, you will still need a copy of ppp.tar.gz since it contains the U-Boot build configuration file (ppp/foss/.config).

Copy this file to the root of your U-Boot source directory, keeping the name .config. You can then use make to initiate the build process.

Build the partitions

Make sure you download an updated file from relases page. You will need to build each partition one by one, setting properly the variables and using specific commands according the selected distribution. When you reach the building repeat advice, come back to this point and build the next distribution.

Arch, Manjaro, Mobian, postmarketOS

For these distributions, download and decompress the image:

$ NAME=arch # set distribution name, i.e. arch, manjaro, mobian, pmos
$ mkdir -p ~/$BASE/downloads && cd ~/$BASE/downloads
$ wget ${NameUrl[$NAME]}
$ xz -v -d -k $(basename "${NameUrl[$NAME]}")
$ mv $(basename -as .xz "${NameUrl[$NAME]}") $NAME.img

Mount the image:

$ cd ~/$BASE/downloads
$ sudo losetup -P /dev/loop0 $NAME.img
$ sudo mkdir -p /mnt/$NAME/boot /mnt/$NAME/root /mnt/$NAME/dev
$ sudo mount /dev/loop0p1 /mnt/$NAME/boot/
$ sudo mount /dev/loop0p2 /mnt/$NAME/root/

Copy root and boot contents:

$ sudo dd if=/dev/loop0p2 of=/dev/disk/by-partlabel/$BASE-$NAME bs=1M status=progress conv=fsync
$ sudo mount /dev/disk/by-partlabel/$BASE-$NAME /mnt/$NAME/dev/
$ sudo scp -r /mnt/$NAME/boot/* /mnt/$NAME/dev/boot

SailfishOS

This distribution needs different commands. Download and decompress the image:

$ NAME=sailfish
$ mkdir -p ~/$BASE/downloads && cd ~/$BASE/downloads
$ wget ${NameUrl[$NAME]} -O artifacts.zip
$ unzip artifacts.zip
$ mv pinephonepro/*/*.tar.bz2 sailfish.tar.bz2
$ mkdir -p ~/$BASE/downloads/sailfishos
$ sudo tar -xvf sailfish.tar.bz2 -C sailfishos/ > /dev/null

Format the partition and copy the extracted files directly onto the device:

$ sudo mkfs.ext4 -F /dev/disk/by-partlabel/$BASE-$NAME
$ sudo mkdir -p /mnt/$NAME/dev
$ sudo mount /dev/disk/by-partlabel/$BASE-$NAME /mnt/$NAME/dev
$ sudo rsync -avz --progress ~/$BASE/downloads/sailfishos/ /mnt/$NAME/dev
$ sudo chmod a=rwx /mnt/$NAME/dev/boot/*

Ubuntu Touch

For this distribution, download and decompress the image:

$ NAME=ut
$ mkdir -p ~/$BASE/downloads && cd ~/$BASE/downloads
$ wget ${NameUrl[$NAME]}
$ xz -v -d -k $(basename "${NameUrl[$NAME]}")
$ mv $(basename -as .xz "${NameUrl[$NAME]}") $NAME.img

Mount the image:

$ cd ~/$BASE/downloads
$ sudo losetup -P /dev/loop0 $NAME.img
$ sudo mkdir -p /mnt/$NAME/boot /mnt/$NAME/system /mnt/$NAME/userdata /mnt/$NAME/dev
$ sudo mount /dev/loop0p2 /mnt/$NAME/boot/
$ sudo mount /dev/loop0p3 /mnt/$NAME/system/
$ #sudo mount /dev/loop0p4 /mnt/$NAME/userdata/

Create the userdata partition and copy system and boot contents:

$ sudo mkfs.ext4 -F /dev/disk/by-partlabel/$BASE-$NAME-data
$ sudo e2label /dev/disk/by-partlabel/$BASE-$NAME-data $NAME-data
$ sudo dd if=/dev/loop0p3 of=/dev/disk/by-partlabel/$BASE-$NAME bs=1M status=progress conv=fsync
$ sudo mount /dev/disk/by-partlabel/$BASE-$NAME /mnt/$NAME/dev/
$ sudo scp -r /mnt/$NAME/boot/* /mnt/$NAME/dev/boot

All distributions

If present, you can optionally backup boot.scr, extlinux.conf and fstab files.

$ sudo mkdir -p /mnt/$NAME/dev/boot/extlinux
$ [ ! -f /mnt/$NAME/dev/boot/extlinux/extlinux.conf ] || sudo mv /mnt/$NAME/dev/boot/extlinux/extlinux.conf /mnt/$NAME/dev/boot/extlinux/extlinux.conf.bk
$ [ ! -f /mnt/$NAME/dev/boot/boot.scr ] || sudo mv /mnt/$NAME/dev/boot/boot.scr /mnt/$NAME/dev/boot/boot.scr.bk

Close any mounted directory window.

Unmount, detach and resize

To unmount and deatch all building images, run:

$ sudo umount /mnt/$NAME/*
$ sudo rm -r /mnt/$NAME
$ sudo losetup -D

On the first boot, if it doesn’t happen automatically, you can manually resize each image to fill the entire partition using GParted GUI software or using the CLI. Please note that SailfishOS doesn’t need any resizing.

$ sudo e2label /dev/disk/by-partlabel/$BASE-$NAME $NAME
$ sudo e2fsck -f /dev/disk/by-partlabel/$BASE-$NAME
$ sudo resize2fs /dev/disk/by-partlabel/$BASE-$NAME

Follow-up notes

Any time a distribution update rebuilds the initramfs it is necessary to delete /boot/boot.scr again to keep the rk2aw menu clean.

In case you want to reinstall only one distribution, the easy way is to delete and recreate the selected partition using the GParted GUI.

If the device doesn’t start, connect a compatible serial cable to the headphone jack and a computer, switch off microswitch 6 and start a serial console to investigate further. Find out the corresponding USB device using ls /dev/ttyUSB* and then connect to it with for example minicom using the command minicom -b 1500000 -D /dev/ttyUSB[...], where […] is the number of the USB device.

To find the exact LABEL, UUID, PARTLABEL and PARTUUID names, open a terminal window on the phone and use the command blkid.

Appendix

Build the postmarketOS image

You can optionally use pmbootstrap to generate the distribution image on your Linux computer, instead of downloading a pre-made image. Make sure you install pmbootstrap before building the image.

Start creating 2 GB empty image file, format and mount it.

$ sudo su
# dd if=/dev/zero of=postmarketos.img bs=1 count=0 seek=2G status=progress && sync
# mkfs.ext4 postmarketos.img
# losetup -P /dev/loop0 postmarketos.img
# exit

Then build the image using pmbootstrap

$ pmbootstrap init
$ pmbootstrap status
$ pmbootstrap pull
$ pmbootstrap install --sdcard=/dev/[LOOP-DEVICE]
$ pmbootstrap shutdown

Troubleshooting

If the PinePhone Pro is not booting (either booting incompletely into a boot splash or tty or if the PinePhone Pro is showing no signs of life) this will typically have the following two reasons:

The battery is fully drained

If the battery is drained then the board can reset during boot causing a boot loop because of undervoltage condition. It can happen on all stages of the boot including U-Boot bootloader, display initialization and USB (re-)configuration. In that case it is not possible to charge the phone. The battery can be charged by interrupting the boot loop by booting the PinePhone Pro into Maskrom mode or by charging the battery externally. It is possible to follow these instructions without a computer by using a wall charger, however it would not be possible to determine if Maskrom mode was started successfully. To boot the PinePhone Pro into Maskrom mode:

• Remove any microSD card from the phone and keep it removed for the below procedure
• Remove the battery, any USB cable and any serial cable
• Reinsert the battery
• Hold the RE button underneath the back cover of your Explorer Edition (or short the bypass contact points on the Developer Edition)

• Connect the phone to an USB port of a computer, while still holding the button for some time
• Confirm if the phone was booted in Maskrom mode:
  • On Linux check if the Maskrom mode appears as device in the output of the terminal command lsusb on the computer, the expected VID:PID of the device is 2207:330c.
  • On Windows this can be checked using the Device Manager and checking the VID “2207” and PID “330c” of an Unknown device appears.
  • On macOS this can be checked in /Applications/Utilities/System Information.app under USB and by checking if the VID “2207” and PID “330c” is appearing for a Composite Device.
• Let the phone charge for multiple hours

The device should now be able to boot from the boot medium again. If that is not the case the installation got corrupted, as explained below.

The installation is corrupted

The PinePhone Pro won’t be able to boot if the installation on the SPI flash, the eMMC or the microSD card got corrupted. To boot a working operating system:

• Prepare a microSD card as explained in the section Flashing to microSD card
• Remove any USB-C cable or device or add-on case from the PinePhone Pro
• Make sure the device is powered off by shortly removing the battery for a second
• Insert the microSD card into the top slot of the PinePhone Pro. Make sure the microSD card is inserted all the way and that the notch of the right side of the microSD card is not visible anymore.
• Power on the device (bypassing the SPI and eMMC might be required, see Boot order)

The device should now boot from the microSD card. If the phone does not boot from the microSD card the microSD card was flashed with an incompatible image or the battery got drained as explained above.

Modem

The PinePhone Pro uses Quectel EG25-G as modem. AT commands are used to communicate with the modem.

AT commands

A list of documented AT commands can be found for example in this AT commands documentation from Quectel. Further undocumented AT commands found by the developer megi, who reverse-engineered parts of the modem and its firmware, can be found on megi’s website here.

To send AT commands to the modem under Linux, minicom or the often-preinstalled atinout utility can be used.

atinout example:

echo "AT+<command here>" | sudo atinout - /dev/ttyUSB2 -

minicom example:

minicom -D /dev/ttyUSB2

VoLTE

The PinePhone and PinePhone Pro modem supports VoLTE and comes with a few VoLTE profiles preloaded. Most operating systems try to set the correct profile automatically.

To list the available VoLTE profiles:

AT+QMBNCFG="list"

+QMBNCFG: "List",0,1,1,"ROW_Generic_3GPP",0x0501081F,201901141
+QMBNCFG: "List",1,0,0,"VoLTE-ATT",0x0501033C,201909271
+QMBNCFG: "List",2,0,0,"hVoLTE-Verizon",0x05010141,201911251
+QMBNCFG: "List",3,0,0,"Sprint-VoLTE",0x05010205,201908141
+QMBNCFG: "List",4,0,0,"Commercial-TMO_VoLTE",0x05010505,201811231
+QMBNCFG: "List",5,0,0,"Telus-Commercial_VoLTE",0x05800C43,201912031
+QMBNCFG: "List",6,0,0,"Commercial-SBM",0x05011C18,201904021
+QMBNCFG: "List",7,0,0,"Commercial-DT",0x05011F1C,201905311
+QMBNCFG: "List",8,0,0,"Reliance_OpnMkt",0x05011B38,201910161
+QMBNCFG: "List",9,0,0,"TF_Germany_VoLTE",0x05010C1B,201909201
+QMBNCFG: "List",10,0,0,"TF_Spain_VoLTE",0x05010CFA,201909261
+QMBNCFG: "List",11,0,0,"Volte_OpenMkt-Commercial-CMCC",0x05012071,201904281
+QMBNCFG: "List",12,0,0,"OpenMkt-Commercial-CT",0x05011322,201911081
+QMBNCFG: "List",13,0,0,"OpenMkt-Commercial-CU",0x05011505,201807052

To select a profile manually, select the best fitting one or a generic one if none fits:

AT+QMBNCFG="select","ROW_Generic_3GPP"

Then enable Voice over LTE using:

AT+QCFG="ims",1

And reboot the modem to apply the settings:

AT+CFUN=1,1

To check the status of VoLTE during a call, the AT command CLCC can be used:

AT+CLCC

+CLCC: 1,1,0,1,0,"",128
+CLCC: 2,1,0,1,0,"",128

In the fourth item of the list, “0” means voice and and “1” means data. If both rows have “1” then the voice call is being carried over VoLTE.

APN settings

The APN setting is only required for a public Internet connection (“data”) on the phone. For tested APN settings and how to apply them see APN settings.

Carrier support

The page Carrier support contains information about the frequency support of different carriers and hints on setting up cellular network connectivity.

Documents

Detailed information about the modem can be found on the page of the developer megi, including reverse-engineered parts of the firmware and its functions. There is also a document about using the modem from January 18th 2020 by megi here. A script at the end of the document showcases a way to power off the modem before powering off the phone, which is integrated into most of the available operating systems.

Firmware update

There is a (nearly) free custom firmware and the stock firmware available for the PinePhone Pro. Both can be updated to a newer version with new features and bug fixes.

Custom firmware

There is a (nearly) free custom firmware for the PinePhone and PinePhone Pro modem by the developer biktorgj, which can be found here.

The custom firmware has various advantages (and zero disadvantages) over the stock firmware, including:

• Signal tracking support with checks against the OpenCelliD database
• Persistent storage is optional and unexpected shutdowns don’t mess up the modem
• A lower energy consumption due to the lower minimum clock frequency
• And many more, see Features not available on stock firmware

The custom firmware can be flashed using fwupd or a flashing script.

Stock firmware

The stock modem firmware can be updated to a newer version if it is outdated. The firmware version can be checked using the following AT command (at the example of atinout, alternatively minicom can be used to communicate with the modem too):

echo 'AT+QGMR' | sudo atinout - /dev/ttyUSB2 -

Pre-update checklist:

Please make sure all requirements of the checklist are fulfilled. If the update process is interrupted it will lead to a corrupted firmware of the modem, causing it to brick. Recovering a bricked modem is exponentially more complicated and requires the user to boot a special mode by physically bridging test points on the modem.

• The battery needs to be charged sufficiently
• The phone needs to be plugged into a charger
• Deep sleep is recommended to be disabled as it can interrupt the update process
• It is recommended to close all other running applications
• Use common sense while doing the update, don’t do the update while being impaired in any way

To get the latest firmware, clone the repository of user Biktorgj on the phone:

git clone https://github.com/Biktorgj/quectel_eg25_recovery

After cloning the directory, open it with cd:

cd quectel_eg25_recovery

Then run qfirehose, which starts the flashing process:

sudo ./qfirehose -f ./

The modem will automatically reboot after the update process is done. The boot process takes around 30 to 60 seconds. After that it is highly recommended to reboot the device.

Firmware modifications

See PineModems for more information regarding modem bootloader unlocking, building a custom modem firmware and modem recovery.

GPS / GNSS

The GPS engine in the modem supports mutli-GNSS reception from GPS, GLONASS, BeiDou, Galileo and QZSS independent of a cellular connection. The operation of the GNSS subsystem can be controlled via a separate set of AT commands, or via qmi. The A-GPS data upload uses the file management AT commands, which also have their own manual. These are linked in the documentation section.

As with most smartphones, the PinePhone Pro has a small antenna and has difficulty getting a first fix without assistance data, a cold start can take 15 minutes under good conditions. The eg25-mananger is configured to upload A-GPS data by default (see here).

Basic testing of GNSS reception can be done by using the AT command interface (/dev/ttyUSB2) from a terminal program like minicom and the data output interface (/dev/ttyUSB1) to feed NMEA data into gpsmon or some other program that can parse standard NMEA sentences.

To check if GNSS data output is enabled, you can

cat /dev/ttyUSB1

this should display a stream of NMEA sentences

$GPVTG,,T,,M,,N,,K,N*2C
$GPGSA,A,1,,,,,,,,,,,,,,,,*32
$GPGGA,,,,,,0,,,,,,,,*66

Further details can be found under Sensors and navigation.

Voice mail

The operating systems of the PinePhone Pro may not have support for accessing your voicemail by holding down the 1-key. Carriers might support accessing the voice mail via an external number however.

Privacy switches

The PinePhone features six switches that can be used to configure its hardware. They are numbered 1-6, with switch 1 located nearest to the modem. Their “on” position is toward the top of the phone.

¹ Note: The baud rate may be 1500000 instead of 115200.

Hardware

Components

Replacement earpieces

The earpiece (or earpiece speaker) refers to the small speaker at the top of the PinePhone and PinePhone Pro.

This part is not available to purchase from the PINE64 Store. However, it is possible to buy a replacement earpiece for another device, and install it in a PinePhone or PinePhone Pro. This documents earpieces that have been tested by the community, and verified to work.

Note that the earpiece dimensions for both the PinePhone and PinePhone Pro are 12x6x2 mm. When looking into earpieces not found in this list, aim for these dimensions.

Notes:

¹ The earpiece is too thin, it can work with padding to keep the contacts together.

² Audio playback is very low quality.

Incompatible earpieces

The following devices are known to have replacement earpieces with dimensions too large to fit inside the PinePhone or PinePhone Pro.

• Blackberry Classic Q20
• HTC Desire 500
• HTC M10
• Huawei Honor 7A
• Huawei Mate 10 Pro

Revisions

• Developer Edition
• Explorer Edition

Developer Edition

The Developer Edition was the first edition of the PinePhone Pro, shipped to developers in December 2021. The aim of the the Developer Edition was to give development community access to the hardware prior to end-users, boost development efforts and allow for porting of existing mobile Linux operating systems to the new hardware. It featured a factory test installation of AOSP as pre-installed operating system and was shipped with the packaging and manual of the succeeding Explorer Edition.

Getting started

This documentation page is strictly aimed at developers receiving their PinePhone Pro dev units. Please note that the following instructions do not apply to Explorer Edition or other future editions of the PinePhone Pro - everything below is only pertinent to the dev phones.

Consider this a crash course rather than a comprehensive overview; you are also welcome to participate in documenting the process (and everything else related to the PinePhone Pro) on the documentation.

Getting the hardware ready

After unpacking the PinePhone Pro from its box, detach the back cover (looking at the back of the phone, there is a fingernail notch on the left leading edge) and remove the plastic tab between the battery and mainboard. You can also flip the headphone jack privacy switch at this point - this enables UART output via the headphone jack. Serial console works the same way as on the original PinePhone.

Factory hardware test image

The PinePhone Pro developer edition ships with a BSP AOSP factory image flashed to the eMMC. This image includes a number of factory applications meant to validate operation of the sensors, the modem, cameras, LCD & touch panel, etc. You’ll have to nuke the AOSP build to run a Linux installation on the PinePhone Pro. Booting from SD with the AOSP factory build present on eMMC is not possible due to the SoCs native boot order.

Changing the language of factory AOSP

This is optional and only if you want to test out the AOSP test image.

1. Swipe up from the bottom of the screen.
2. Tap on the Gear icon.
3. Tap on the 2nd from last option that has an i inside of a circle icon.
4. Tap on the first choice with the globe icon.
5. Tap on the first choice with the language icon.
6. Tap on the second choice to add another language.
7. Tap on your language in the list.
8. If there is a secondary choice required, tap on the preferred country.
9. Tap the four horizontal bars icon to the right of the new second language and drag to the top of the list to set the new language as the default.

Backing up the factory AOSP

It may be a good idea to create an image of the eMMC in case you want to flash it back. Free up at least 117GB of disk space. Install adb.

adb root && adb pull /dev/block/mmcblk1 ~/pinephonepro-factory-AOSP.img

Nuking the factory AOSP installation

To be able to boot from the microSD card easily it is recommend to wipe the bootloader from the pre-installed operating system on the eMMC due to the eMMC being higher in the boot priority than the microSD card.

Method 1: Via ADB

In the factory test image, navigate to setting (gear icon) > at the very bottom of the settings list you will find a phone icon with rk3999mid written underneath it > tap the last (bottom) setting 7 times in quick succession. Following this, you may need to do the following: open the Settings application and enable USB debugging in Settings > System > Developer Options > USB debugging. Then connect the PinePhone Pro to your PC with the supplied USB-C cable.

Please note: It is recommended to charge the device to at least 50% before proceeding with wiping the eMMC.

Connect the phone to your computer and check adb devices in the terminal. The phone should be registered as attached. If the device doesn’t show you may want to try a different port or cable. Then enter adb shell followed by su to gain root access. At this point you can erase the eMMC installation:

cat /dev/zero > /dev/block/mmcblk1

The phone will freeze and then the screen will go blank. Let it sit for no less than 10 minutes and then power it off by holding down the power button. You’ll know the phone is powered down when the notification LED turns off.

Method 2: Via serial cable

Another method of erasing the image is to connect serial console, break into U-Boot when it says to press Ctrl-C, and then the “mmc erase” command can be used to zero blocks on the eMMC. For example, “mmc erase 0 16384” will zero the first 8MB, and is enough to stop it from being bootable. The baud rate for the serial console is 1500000.

Flashing Linux

You will want to do all your testing and development on a SD card; you DO NOT want to flash an OS to eMMC at this time. Builds frequently break at this early development stage and recovering from a corrupted eMMC installation is presently time consuming and tedious. A fast 16-64GB micro SD card for $15 will work just fine.

There are a handful of OS builds available for the PinePhone Pro already. These can be found under the Software Releases section.

If you are a developer porting your own distribution to the PinePhone Pro, please make sure to make an entry for it in the Software Releases section on the documentation. If you want / need help with entering your build onto the documentation please ping one of the mods or admins in the chats (see Forums and Chats drop-down menu).

Upstreaming status

Levinboot-based kernel development image

This guide will help you get a comfortable environment for testing your kernel builds on Pinephone Pro. It assumes you either already know how to build or cross-build a Linux kernel for arm64, or if you have a way to get a pre-built kernel from somewhere. For a quick test that your setup works, you can use megi’s pre-built kernels.

Quick and easy way to get started with kernel development and testing is to use CrystalGamma’s Levinboot patched with support for Pinephone Pro and 3-option boot selection using volume keys. You will be able to switch between kernels quickly without swapping uSD cards, which is necessary for painless kernel development experience.

1. Create a following partitioning scheme on a uSD card using sfdisk:

label: gpt
first-lba: 64
table-length: 8

start=64, size=8128, type=D7B1F817-AA75-2F4F-830D-84818A145370, name="sd-lboot"
size=60M, type=E5AB07A0-8E5E-46F6-9CE8-41A518929B7C, name="sd-lpayload1"
size=60M, type=5f04b556-c920-4b6d-bd77-804efe6fae01, name="sd-lpayload2"
size=60M, type=c195cc59-d766-4b78-813f-a0e1519099d8, name="sd-lpayload3"
size=14G name="sd-rootfs1"
name="sd-rootfs2"

This can either be done interactively, or by saving the above to a file, like format.txt, and running sfdisk /dev/<sdcard> < format.txt

2. Write Levinboot to sd-lboot partition using dd. You can get a pre-built and tested version here There are two options levinboot-sd.img and levinboot-emmc.img you can use either one of them for your sd-lboot partition. They differ in where they load the payloads from (either from SD or eMMC) and not in where they can be flashed to. For uSD card only workflow, you’ll want levinboot-sd.img.

3. Prepare payloads for Levinboot and copy them to appropriate partitions. Partition sd-lpayload1 is used by default, sd-lpayload2 when you hold a volume down key during powerup, and sd-lpayload3 when you hold the volume up key.

Preparing a payload involves getting a TF-A bl31.elf build, kernel Image build, DTB file for Pinephone Pro, and optionally an initramfs archive, modifying DTB to include kernel boot arguments, and compressing these using lz4 in specific order, as shown below.

BOOTOPTS=(
        console=tty1

    earlycon=uart8250,mmio32,0xff1a0000
    console=ttyS2,1500000n8

    root=PARTLABEL=emmc-rootfs1
    rootfstype=f2fs
    rootflags=fastboot
    rootwait
    rw

    loglevel=7
)

BOOTOPTS="${BOOTOPTS[@]}"
ALGO="lz4 -zc"

cp -f rk3399-pinephone-pro.dtb board-cfg.dtb
fdtput -pt s board-cfg.dtb /chosen bootargs "$BOOTOPTS"

(
        $ALGO bl31.elf
        $ALGO board-cfg.dtb
        $ALGO Image
.       $ALGO initramfs.img
) > payload.img

dd if=payload.img of=/dev/disk/by-partlabel/sd-lpayload1 bs=4M oflag=direct

4. Prepare root filesystem. You can use any Linux distribution for aarch64 for development. For example if you want to use Arch Linux ARM, you would need to format the sd-rootfs1 partition with f2fs filesystem and extract the Arch Linux ARM rootfs tarball there. That will give you a bootable SD card image for Pinephone Pro.

5. Repeat steps 3 and 4 if you want either more kernel payloads, or more Linux distributions on the same uSD card. I recommend having at least some module-less working kernel in sd-payload3 and perhaps a small userspace in sd-rootfs1 with a pre-configured WiFi connection, that will allow you to always quickly recover if your development kernel fails to boot, just by pressing volume up key during boot and updating the the kernel in one of the primary payload partitions over WiFi.
