I am a new samsung owner. I recently got s21 ultra t-mobile branded. It is now network unlocked. But i wanted to have a clean bloat free phone so wanted to have unlocked firmware.
As i understand it, i need XAA G998-UA firmware which i downloaded from frija. Do i need to use patched odin or regular odin 3.14.4 would work? If i need patched odin what is the recommended one with link if possible.
Finally, is it recommended to flash home csc or csc, i would like to keep my data but not sure if any problems will happen if i choose home_csc
Appreciate your kind help
