FLASHING THIS FIRMWARE

Using the provided script

If you ever flashed an Android phone, this should be even easier:

  1. Get required tools: you need fastboot installed in your pinephone
  • Debian/Ubuntu based distros:
  • apt install android-tools-fastboot
  • OR apt install fastboot
  • postmarketOS / Alpine: apk add android-tools
  • Arch/Manjaro: pacman -S android-tools
  1. Get latest release from Github
  2. Unpack the package.tar.gz file in some directory: tar xzvf package.tar.gz
  3. Execute the script included in the file: ./flashall 4b. If the modem doesn't disappear when the script starts, try running the flashall script as root
  4. Wait for the modem to come back

ADSP Versions

If your Pinephone / Pro came with a really old stock firmware, you might need to update it

Flashing it:

  1. Open a root terminal and run: echo -ne "AT+QFASTBOOT\r" > /dev/ttyUSB2 to enter fastboot mode
  2. Run fastboot flash modem NON-HLOS.ubi && fastboot reboot

Flashing manually

  1. Get required tools: you need adb and fastboot installed in your pinephone
  • Debian/Ubuntu based distros:
  • apt install android-tools-adb android-tools-fastboot
  • OR apt install adb fastboot
  • postmarketOS / Alpine: apk add android-tools
  • Arch/Manjaro: pacman -S android-tools
  1. Grab a copy of the firmware, and, optionally, a recovery firmware (https://github.com/Biktorgj/quectel_eg25_recovery)
  2. With the modem active, jump to fastboot mode:
    • As root, tell the modem to shutdown and enter fastboot mode:
    • echo -ne "AT+QFASTBOOT\r" > /dev/ttyUSB2
      • If the AT interface is not available, you can also do it from ADB:
        • If running stock: adb reboot bootloader
      • If already running this firmware: adb shell reboot; fastboot oem stay
  3. After a bit, if you run lsusb you should see the modem in fastboot mode:
  • Bus 003 Device 005: ID 18d1:d00d Google Inc. Xiaomi Mi/Redmi 2 (fastboot)
  1. Once in fastboot mode, first flash the unlocked bootloader:
    • fastboot flash aboot appsboot.mbn
    • After that fastboot reboot ; fastboot oem stay
  2. After flashing and rebooting to the bootloader the modem will say FAILED (remote: 'Waiting for orders!')
  3. Now you can flash everything:
  • fastboot flash boot boot-mdm9607.img
    • If you get an error flashing the kernel, run fastboot flash:raw : fastboot flash:raw boot boot-mdm9607.img
  • fastboot flash recovery boot-mdm9607.img
  • fastboot flash system rootfs-mdm9607.ubi
  • fastboot flash recoveryfs recoveryfs.ubi
  1. After you flashed everything, you can run 'fastboot reboot' and wait for it to come back (you might have to run fastboot reboot twice to clear Quectel's bootloader flags).
  2. If all has gone well, to enable adb you will likely need to send the "AT+ADBON" command to the modem.
