Installation

Using pmbootstrap

  • pmbootstrap init

User interface: xfce4

  • pmbootstrap install --android-recovery-zip

To flash the image to the device: Sideload the zip by following this command:

  • pmbootstrap flasher --method=adb sideload

Important notes

  • If build failed try looking at the logs pmbootstrap log make sure patches are all OK. Every patch is necessary for functioning the device correctly including the touchscreen, display...
  • Before running nmtui to setup the wireless connection make sure you set the interface wlan0 state to up by typing this command: ip link set wlan0 up if you get ip: ioctl 0x8914 failed: Operation not permitted make sure the bcmdhd_mfg.bin and nvram_mfg.txt are in the right path.
  • sideload completes at ≈50% that's totally fine.
  • added a patch to the kernel to fix swapped colors (orange,blue) booting will feel it's broken but it's fine.
  • I didn't try other UIs you can test them and edit this page.
  • Make sure that systemd in pmbootstrap init is set to never i wasted much time figuring it out, if set to default kernel won't boot.
  • Flashing with heimdall (pmbootstrap flasher flash_rootfs) fails at 9-11%. TWRP works.
  • pmbootstrap flasher flash_kernel works without any errors.
