My friend bought an android phone from AT&T. Recently she unlocked it, and she was able to use other sim cards, but the phone was still branded with the AT&T logo and loaded with its software. The phone can’t make any over the air updates because it relies in AT&T to fetch carrier specific updates… which fails when she switches providers.

I’m torn because it’s either flash unofficial firmware from the internet or live without security updates until she buys a new phone, both of these undesirable from a security perspective. The phone was just released 4 years ago and it is in good shape; but all that flies out the window because of this and related stupid practices.

I’m not sure if that is also addressed.
