Hello guys! I want to sim unlock a Note 2 from AT&T. I've have read already the process to do it but I have a few questions before I do it.
The phone is actually in version 4.4.2 and modem/baseband NJ2.
I read that I need to downgrade modem to LJ2 modem using a custom recovery.
First question is if by flashing a custom recovery would it trip the Knox counter and if yes, is there a way to do it without tripping Knox?
Also where could I find a copy of my current modem NJ2? The last one I found is NJ1.
