that sounds like a hardware problem.hey man, I've tried the guide for crossflashing OPID mismatch and followed everything. I've managed to get into download mode by using QFIL and deleting partitions. once i was inside download mode I tried flashing an old stock stock rom kdz (android 9) because the android 11 kdz (didn't work it would just keep on restarting on the LG logo). on Android 9, i actually reached the setup area where you choose language and all that. but the problem still persists where my phone keeps restarting and overheating..
