It might brick your phone, however it's covered under warranty since its still rooted and the original bootloader so just take it back for a swap.

Anyway, just boot into recovery (Vol-Down + Power, then select Recovery)
Then press Vol-Up + Power and select Apply sdcard:update.zip
If it loads into a black background with green writing then take a photo or let us know. You should just be able to reboot your phone after by removing the battery....
HOWEVER, I take no responsibility if this bricks your device! By trying this you understand and agree that I am not responsible for any negative outcome
