Questions About SIM Unlock

Hello.

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:
  1. Is there a way to fix Wi-Fi on my phone?
  2. Will upgrading to 4.3 be worth it, or will there be any risks?
  3. Will upgrading/flashing a new (stock) rom bring back the SIM lock, or am I done with that?

Thanks.

1) there are several ways. You can start by downgrading your modem to its original since you are still on older firmware and see if that works
2) not very risky, just make sure you know about Knox and all that
3) Nope, unlocked for good

Thanks!

I'm so happy to know that it's gone for good. That means I could probably just flash a stock 4.3 rom and get the matching modem with it, and hopefully have wi-fi working, right?
