Download your Carrier/Region RUU, run on PC, you can find the 'ROM.zip' on %temp% folder. Extract 'Recovery.img' with 7zip copy it to SDK (ie. C:\android) folder on PC. Flash recovery as
fastboot flash recovery recovery.img
and lock the bootloader (you can unlock and re-root again)
Now run the RUU on PC. Thats'all. It'll restore to your old STOCK ROM. However your boot loader will ***RELOCKED*** but you can unlock, re-root with your Unlock_code.bin which you got first time rooted.
fastboot flash unlocktoken Unlock_code.bin
