I just bought a unlocked at&t Galaxy S22 Ultra and I am using it on my Tmobile service right now and I can't get it to update to Android 13 and when I check for the software update it says it's up to date on the android 12 version. Can anyone help me with getting it upgraded to Android 13?
Solved! Go to Solution.
You can try installing SmartSwitch on your PC/Mac computer, and seeing if it will locate and install an update. Other that that, you might want to reach out to T-Mobile and see if they can help as the device is now set to use their OTA servers, and it is their servers telling you that no update was found.
@userqPjstdROzG The issue is that your phone currently has AT&T firmware on it and you won't find an update of that on T-Mobile's update server.
The solution is one of the following:
- Temporarily insert an AT&T SIM into your phone and check for updates on Wifi. The AT&T SIM card does not have to have live service. When you insert the SIM card the phone will read and load the AT&T update servers. When you check for an update on Wifi, it will find the AT&T firmware update that you are looking for.
- The other solution is to reflash the phone with either unlocked firmware OR T-Mobile firmware. Then you will find an update on T-Mobile's update server.
