Have an unlocked Verizon prepaid Moto E4 running with a T-Mobile SIM card on the T-Mobile network.. Getting messages to update the phone software, 1. Can I do that via Google Play for APPS like Chrome, GMAIL, etc,, and also the Android phone system software without bricking the phone? I do not have the original unlock code. 2. If I do a factory reset will it destroy the network unlocking and brick the phone?
