Had a TWRP backup of my 2063 ROM (Russian), tested it by restoring and all was well. Installed and tried out 2 custom ROMS ( Bliss, MSM Extended ), wanted to return to original Realme 6 Pro ROM; after wiping cache, formating data, tried to restore with my good TWRP backup and the dreaded "extractt TarFork() process ended with ERROR:255" appeared near the end of the data partition. Unfortunately I do not know the full name/description of the stock ROM that was on the phone, so I am doing a trial-and-error method with, so far, 2 (both 2061 ROMS). Just boot loops are the result. Any Suggestions?
