I hard bricked my device today (doesn't even turn on - can't even get into fastboot recovery). I'll explain what happened so perhaps others can avoid my mistakes in the future.
I was using:
Platform-tools Version 34.0.1-9680074
Factory image raven-t3b2.230316.005-factory-3923dd64
Magisk v26.1
Magisk patched my boot image, named: magisk_patched-26100_Xq7GU
I followed this guide to the letter (I think
), however, I did not read any of the thread past the OP before starting.
I encountered a boot loop after Step 8 of Initial Root / Create Master Root Image, and doing a fastboot reboot. I did not specify a boot area
fastboot flash boot[_a or _b] <drag and drop master root.img here>.
After encountering the boot loop, I tried to flash the original boot.img from the factory image, reflashing the magisk patched, but none of it was able to recover from the boot loop.
I then made the mistake which led to a hard brick, which was to flash the original boot.img to boot_b (fastboot flash boot_b boot.img) and use fastboot --set-active=b to force the bootloader to use that (I am not an expert, I did not know the consequences, and I take full responsibility for taking these matters into my own hands instead of asking for help). My device began to bootloop for several minutes, although the bootloop was extremely quick compared to before so I thought it was a positive sign. However, I then decided to hold the power button to force it off and boot into fastboot/recovery. Once powered off, it no longer powers on and it is hard bricked.
This was a few hours of frustration condensed, so perhaps I've overlooked some things, but felt worthwhile to post here in case anybody is interested.
