How can I reset an IMEI unlocked tethered jailbreak iPhone 4 with iOS 5?

I own an iPhone 4 iOS 5.1 tethered jailbreak bb 4.12.01 Sim got locked.

I recently had it unlocked from a shop. Now I need to reset phone, but the tethered jailbreak disables me from doing that. I was wondering if I could restore with a .ipsw like iOS 6 or 5.1.1 etc and finish the unlock process?

Thank you sooooo very much!
