Prior to doing any custom roms i did attempt to put in my other phone's att prepaid sim card and tried to do the check for updates to get it from android 7 to android 8. I left it in all night and checked the next morning, it kept saying no updates available.
Is it not available via prepaid at all? Or if so, does this mean actually contacting att and having them fully register it in the system not just swapping the sim card temporarily from my existing phone?
Which OTA updates are currently the latest being pushed (is it 8.1?)
I'm assuming that also, once a custom rom is installed, OTA pushes wont work regardless and it must be reverted back to stock (could also have been the issue)?
Thanks in advance
