if you still have a custom recovery ,flash a stock ROM from here : http://android.clients.google.com/packages/ota/google_crespo/VQ8PQk_V.zip - thanx quantumrand ,but before that wipe CACHE ,DATA & DALVIK ,you can find a small tutorial of mine here : http://androidforums.com/nexus-s-all-things-root/465477-rooted-not.html - see the part involving the custom recovery & how to flash it !

After you install the stock ROM , go to the tutorial and see how to download/use Android SDK and drivers ,how to enter bootloader !
After you see the paces type this in your CMD window under the same path [for ex : D:\Android\sdk\platform-tools] and type this : fastboot oem lock > you are unrooted and the bootloader is locked so you can take advantage of your warranty again !


Any questions ? Ask me !
