Alright no luck so far. I've used the following combinations to no avail:
- Your boot + your vendor + Andy Yan's LineageOS 17.1 A/B
- Your boot + your vendor + Andy Yan's LineageOS 17.1 A only
- Your boot + A11 treble vendor + Andy Yan's LineageOS 17.1 A/B
- Your boot + A11 treble vendor + Andy Yan's LineageOS 17.1 A only
- Your boot + A11 treble vendor + Andy Yan's LineageOS 18.1 vndklite A/B
All of these scenarios result in bootloops. The only combination that got me the furthest is:
- Treble 9 boot + your vendor + Andy Yan's LineageOS 17.1 A only
This one gets me to the OS boot screen but hangs and never loads system successfully.
