You mean you unlock when you're at 7712 or you need to downgrade again and unlock and upgrade to 7712.how did you unlock with 7712.After seeing that most people had no problems and the unlock carried over I was surprised to see that this didn't work for me. It worked going from NoDo to 7661. But when I upgraded the LG Quantum from 7661 to 7712 it was locked again and I had to unlock and disable the relock again.
so, most likely it will work, but there is a chance it may not.
