I had the same problem. It looks like there is a problem with the latest ROM. I went back to the one on november 20th. All you need to do is put it in boot loader mode which is done by completely powering off the phone, then holding down at the same time the top power button, volume down, and the call end button. If done successfully you should end up with the tri color boot loader screen. From here just connect it up to your computer and flash with an older ROM. It should work without any problems.

Good luck.

Or do what dicast says. both methods work.
