Got a phone from a foreign country.

[dlmrn23]

Hi, so I got an AT&T Galaxy S10+ (SM-G975U) from the US and it was stuck at Android 10. I can't get any updates so I tried to flash a new firmware into my phone. The problem is, SamMobile doesn't provide AT&T firmwares for SM-G975U but other carriers like T-Mobile and Verizon is available. Can I use firmwares from other carriers for my AT&T phone?

I would advise anyone looking to update not to update beyond Android 11. Android 12 has issues and not just on Samsung devices. You can download Android 11 for all US Variants here.
