I'll try to produce a boot image instead now.
With warm restart console-ramoops enabled. So that way simply getting the phone to reboot on the black screen might get back to a stable rooted boot, where console ramoops will be that of cleanslate temp-booted.
I hope temp booting with fastboot still works on op8/pro's these days with 'fastboot boot boot.img', otherwise for now I'm out of fresh ideas.
Will post the boot image in a bit
So here's the boot image, only the kernel image replaced inside based on this firmware zip OxygenOS 12.1 IN2023_11_C.21:I will try to get a log for you tomorrow, its time for bed now.
anyway my first attempt would be a working a12 recovery, the one i tested (aicp) gave me a error message that an image boot or recovery is broken (had stock boot img with magisk at this moment flashed) after flashing orignal recovery i could boot again but obviously without adb working in recovery mode.
if you have a hint of a working recovery i will try my best to help you here.
these are the files from /sys/fs/pstore/console-ramoops
idk if they still help but thats what i can do for today.
