    Default T-Mobile Galaxy S3 with AT&T Software

    Hi there, for a long time i wanted to update my S3 from Android 4.1.2 to 4.3 or 4.4 but i can't i'm not in the US and i dont have it unlock so i see in the back of my s3 and says T-Mobile but the carriers app on the phone are from AT&T so i was wondering if the reason that i can update my phone is for not being unlock or for having a diferent android?

    BTW, i found the stock update to 4.3 for AT&T users and i was wondering if i could installed?

    I will really appreciate an answer!

    Update files usually check what model number you have. If they don't match, the update won't install. One thing I am confused on is: you don't usually install a different carrier's ROM. That usually leads to a bricked device. So, the fact that you have a TMobile device but with AT&T software confuses me.

    Did you buy this device used?
