Additional Notes

• vbmeta need to be flashed with this command:

fastboot --disable-verity --disable-verification flash vbmeta vbmeta.img

• To boot Android 10 GSI or newer, you'll have to replace these files in vendor partition with files extracted from Xiaomi Redmi 8, or the phone will boot loop:

/vendor/bin/hw/android.hardware.graphics.composer@2.1-service
/vendor/lib64/libsdmcore.so
/vendor/lib64/hw/android.hardware.graphics.composer@2.1-impl.so
/vendor/lib64/hw/hwcomposer.msm8937.so

• This device is eSIM only. If you want to use mobile data, you have to extract and place these files to register a new eSIM profile:

/system/app/EuiccOverlay/EuiccOverlay.apk
/system/priv-app/EuiccGoogle/EuiccGoogle.apk
