Ubuntu Touch adaptation for the Lenovo Tab M8 HD (2nd Gen) (8505X/F)

How to build (You can skip this, also outdated)

To manually build this project, follow these steps:

./build.sh -b bd  # bd is the name of the build directory
./build/prepare-fake-ota.sh out/device_akita.tar.xz ota
./build/system-image-from-ota.sh ota/ubuntu_command out

Install

  1. Unlock the device bootloader following usual unlock procedure (enable Developer mode, turn on "OEM unlocking" option, then reboot to bootloader and execute fastboot flashing unlock
  2. Use SP FlashTool to downgrade the device to Lenovo_Tab_M8_TB-8505X_MT6761_S100064_200901_BMP. Make sure to select "Download-only" option, as "Format all and download" will erase important device-specific configuration like NVRAM partition.
  3. Check that stock Android still boots (may take a few minutes for the first start), then reboot to bootloader again and execute the following commands with files downloaded from Actions job upload artifacts:
fastboot flash boot out/boot.img
fastboot flash system out/system.img
fastboot format:ext4 userdata
fastboot reboot
