I have the SGH-M919 with the following details:
Android version: 4.2.2
Baseband version: M919UVUEMK2
Kernel version: 3.4.0
Build number: M919UVUAMDB
This is after using various guides to rooting, getting rid of the SIM lock, changing the baseband version and reverting it.
Right now the phone works, I can make calls and the sound is fine. However, I can't turn Wi-Fi on. Thus, I have a few questions:
- Is there a way to fix Wi-Fi on my phone?
- Will upgrading to 4.3 be worth it, or will there be any risks?
- Will upgrading/flashing a new (stock) rom bring back the SIM lock, or am I done with that?
