Ever since my update from Oxygen OS 10.3.8 to 11.0.0.2, I've had a major issue where the lock screen image doesn't match the input (the pattern or number pad is bigger than the glass, but the touch input doesn't know this and expects the correct input.) Last night I tried a factory reset, had a ton of issues in set up including constant flickering and being stuck on a black screen, but after a forced restart, everything seemed perfect. Then this morning the lock screen glitch resurfaced. So I went down this rabbit hole.
Among other things, I successfully put Lineage 18.1 with Gapps on, but I'm not crazy about it and just wish I was back on 10.3.8. But I cannot for the life of me figure out how to sideload the 10.3.8. I could not get the TWRP flash boot to work - the phone sits froze with a 1+ logo and I have to type in
which still works fine. I attempted to use Magisk while in Lineage 18.1 to make a 10.3.8 image that includes Magisk, but I'm not sure that's possible (maybe you need to start on 10.3.8?) At any rate, the image I made with Magisk, pulled off my phone and tried to fastboot flash boot to would not boot, and instead I'd get stuck on the bootloader without being able to enter recovery. But I could always reload the Lineage recovery and boot into it, and reset back to Lineage if needed. But that's not what I want.
