From what I understand,(which may be wrong) all you need to do to go back to stock and relock is flash the stock rom cause the unlocker is not write protected. I thought that if you got the .41 unlocker to finish , then you were unlocked ready to flash a nongps rom. But, that's not what you want so if you flash the stock Verizon rom you should be back to square one. Like I said before, maybe ask the person who made the unlocker. You could try flashing a different Verizon stock rom or you could try running the 2.31 unlocker again and see if it succeeds to get you unlocked.
