Hi, can anyone help me?
I dirty-upgraded from version 17 to 18, and after that I dirty-upgraded to 19. I made a backup of version 17 beforehand.
After upgrading I wanted to roll back to version 17. I wiped all the data and did a clean install, but the system doesn't want to boot. After restarting, my phone boots to a black screen (with the green LED for microsecond) and then boots back to TWRP on its own.
Now all I can do is install a clean version 19 and use it. The backup doesn't want to boot, giving an error `extractTarFork() process ended with ERROR: 255`. Both clean installed 17 and 18 versions are won’t boot.
I even updated TWRP, but it had no effect.
What can I do?
Thanks.
