Xiaomi Mi 8 SE
Tried with both system-quack-arm64-ab-vanilla and gapps version.
Device is using system as root and supports treble as per Treble Info app
Using as base xiaomi.eu 9.10.24 (Android 10), so it's an Android 10 vendor / firmware
Tried with TWRP 3.2.3-1227 and 3.3.1-1024
Procedure: flash 9.10.24, boot, reboot to recovery, factory reset, flash system image, reboot.
Device is stuck on Mi splash screen for ~5 seconds, reboots a couple times, does the same thing, then boots to recovery. No bootanimation, so I'm not even sure it's a bootloop, seems like it can't start the system at all.
Can't grab logs as adb is not running at the splash screen, also /proc/last_kmsg doesn't exist in recovery.
Let me know if there's anything I can do to get more information to fix this, or if anyone on Mi 8 SE managed to get a quack GSI to run, thanks.
