Default [Q] Problem completing AT&T issued SIM unlock

I recently converted by AT&T version to a Google Edition via S-OFF, CID change and Google 4.4 RUU.

AT&T has tried to issue me unlock codes twice, but neither works. I'm using an old t-mobile SIM to attempt the unlock.

Does anyone know if maybe updating the CID impacts the ability to use a carrier unlock code?

Install a stock at&t ROM and try again. In multiple threads it has been said that the at&t unlock code only works on stock roms
