Samsung gt-i9020a (nexus s) wont turn on

[mboy12]

Hi, I was trying to root my phone, a Samsung gt- I9020a (nexus s). I was following this tutorial : How To - Root the Samsung Nexus S - YouTube. When attempting to load a recovery img the first time it did not work so I googled this issue and found this: Update Nexus S 4G I9020A with ClockworkMod 6 (CWM6) Custom Recovery | Team Android. I proceeded to download and load the ?ClockworkMod 6 recovery image? onto the phone by following the steps. Now my phone will not turn on even when holding the volume up+power button startup. Is there anything I can do??? Please help. Is my phone hard bricked with no chance of fixing?
