Noooooo!
DO NOT ACCEPT AN OTA WHILE ROOTED!!!
This can Bork your phone or worse, brick city.
You rooted your phone and loaded a custom recovery. Once this is done you removed the phones means of properly accepting an OTA. The stock recovery's only purpose is to accept said OTA, but you loaded a custom recovery. There is no telling what might go wacky when this is done.
Please power off and then boot into hboot. (volume down and power for a few seconds)
Once you see the white screen with Andy riding a skateboard, this is hboot.
Post back with exactly what you see on this screen.
You never need to accept an OTA again, you're rooted. You can usually flash the updated stock Rom before It's available to non root users.
Go to the roms and kernels sticky at the top of the forum and look up the latest OTA rooted stock Rom. Download that and flash.
Pow! You're updated.
Or you can look up MikG, which is 10 times better. Either way, you will be updated.
