So, I've never had a Xiaomi before, and i wanted to upgrade mine (MI 10T) to the newest version...The thing is that I can't find my device version anywhere to download the correct upgrade package...I have MIUI 12.0.3.0(RJDEUOR) but usually the more common letters are RJDEUXM and stuff like that... I've tried to download different archives but none of them work... Somebody can help me?
