About GSI 

Any GSI without gapps is stable, you can chech the list here
But for just information

  • AOSP don't ask it just light because nothing customize in it
  • Arrow OS is have great performance but lack of feature and have some much bug
  • Crdroid this in mid between performance and feature
  • Corvus not good meybe in performance but good compability with skiavk and NTFS
  • PalyrimOS this mid too
For GSI Fix such as brightness, etc check here

Resize Partition

Naming <ARCH>_xyZ{-lite}

<ARCH> = determine Arcitecture type
can either be arm, a64 or arm64

x = determine dynamic partition or not

can either be a or b
  • b = a/b
  • a = a-only

y = determine gapps type 

can either be v, o, g or f
  • g = gapps
  • o = gapps-go
  • v = vanilla (no gapps included)
  • f = floss (free & open source apps instead gapps)

Z = determine Superuser access

can be N, S, or Z
  • N = no superuser
  • S = superuser included
  • Z = enhanced dynamic superuzer

-lite = determine vndklite

Android11 for vndklite vendors Usually for android Go

For example, "arm64_bvN" is ARM64 A/B vanilla with no superuser.

Resize Partition

this will expand up to 4.8GB, Need : Odm & Vendor that you have backup
  • fastboot flash super /path/resizer.img
  • fastboot flash odm /path/odm.img
  • fastboot flash vendor /path/vendor.img
  • fastboot flash system /path/system_gsi.img

Install GSI From Fastboot

Require Stock Recovery M0D (Fastboot)
  • To format the system partition
    fastboot erase system
  • If the file is system.img :
    fastboot flash system system.img
  • If the file is super.img :
    fastboot flash super super.img
  • If GSI size is more than 3.4GB
    fastboot delete-logical-partition product

If the command fails use Install GSI Universall

  •  -Select Back to recovery
  •   Format the data then reboot into the system

Install GSI Using Universal Method

The way to install GSI is really simple (I think) for all vendors without exception

Backup vendor and odm from
dd if=/dev/block/mapper/vendor of=/sdcard/vendor.img
dd if=/dev/block/mapper/odm of=/sdcard/odm

GSI Installer

  • Download the GSI that you want to use from the treble list
  • Download the latest version of GSI Installer along with resizer.img
  • extract GSI Installer in any folder
  • Extract resizer.img to GSI Installer folder
  • Extract the GSI to the GSI Installer folder and rename it to system
  • Put odm and vendor in device folder
  • Open the FLASHROM.bat file then select it
  • Select option 1 flash system
  • Select option 2 then flash system reparted
  • Wait until all processes are complete
  • Reboot 2 times and factory format
  • In case of loop install vbmeta-patch in odin AP
This method also repartitions the system so that you can install more GSI than you can do
