Default [Q] AT&T Galaxy S4 SGH i337 4.4.2 Unlock help??

I just bought this Galaxy S4 from someone but the thing is i use MetroPCS and when i insert the SIM card it asks for a pin number. Does anyone know how to unlock it. I understand i might have to root and downgrade but im a noob. Thanks in advance!!!

Do the downgrade and root, and while on MK2 use the "Possible SIM unlock for MK2" thread.

To go from 4.4.2 to 4.3 is somewhat possible, other downgrades aren't possible. There's a thread titled NB1 DOWNGRADE with the information to do that. Check your baseband first, if you're on NC1 you might need to flash NB1 first.
