So I have an unlocked Galaxy S4, that came from AT&T.
It's horribly out of date. Still running Android 4.2.2. I notice that it keeps randomly rebooting itself lately, so I'm thinking the old software is to blame.
But when I go to update via settings, it tries the AT&T update utility, which is all fine and good... except it doesn't have AT&T service so nothing happens.
What do I do here?
If it helps, it has a Metro/T-mobile SIM in it.
