I installed firmware 188.8.131.52 (11), android 12 beta and android 13 beta and everything didn't work. I can't receive OTA Updates because i had an unlocked bootloader. I relocked it some time ago, but since the unlock app isn't available anymore i can't unlock it again. So a custom rom is not an option. I tried to install different asus firmwares manually, but the phone doesn't recognize them. They were placed in the root. Can please anyone give me advice?
