i need help please........ I have a S20 5g SM-G981U T-Mobile phone that is unlocked. It has tmobile bloat on it......now for the issue.... I am on AT&T and have tried to flash U and U1 variants to get a Stock AT&T bloated phone with no success. It boots with the tmobile splash screen on every U firm ive used. I can get U1 with no bloat from anyone which i think is basic samsung firm. i dont like all of att bloat but do like some of the carrier enabled apps, so im looking to flash the stock att firmware. Also no matter what the carrier version always says TMB/TMB/TMB/. i have my att sim card in now and everything works, but its wont flash to a stock att rom with att carrier settings. Can anyone point me in the right direction? i have tried the OP files and method several times.
