FP3 custom rom development based on released source code

I am unsure if anybody is interested, but I don’t have the computing power on my T420 or experience to try this, but someone has created a UBPorts halium 9 GSI. It’s in very early stages but the instructions are as follows https://build.lolinet.com/file/halium/GSI/ubports_GSI_installer_v3.zip

  1. Install treble compatible android 9 rom
  2. FORMAT data in twrp
  3. Flash halium-boot.img of your device
  4. Flash GSI zip https://build.lolinet.com/file/halium/GSI/ubports_GSI_installer_v3.zip

if there’s no halium-boot for your device, build it without android environment!

  1. Get kernel source
  2. Patch defconfig using this script: https://github.com/erfanoabdi/halium-boot/blob/master/check-kernel-config
  3. Build kernel and flash it (using anykernel or any other way)
  4. Flash https://build.lolinet.com/file/halium/GSI/tools/halium-ramdisk.zip
