Android phones, apps and tablets

Bought the G2 off mashton, but unfortunately it's still locked.
I paid one of those online places for an unlock code but that didn't work.
He's put cyanogenmod on it, do i need to flash it back to an EE stock room for the unlock code to work?

Sounds like he has rooted and loaded the Cyanogemod ROM. However this will not unlocked the G2 as its locked by the bootloader.

Even if you go back to stock your code won't help.

Ideally mashton might have also changed the bootloader, but as its rooted already you can use the loki tool to get it working.
