I recently rooted my phone. I have not done any custome ROMs and only had it overclocked for a couple hours (it wasn't stable enough for me.) I've got a back up saved on my home computer. This morning I got notification of an OTA update from T-Mobile. I did the update and now the phone is stuck on the Samsung Vibrant screen. What do I do? Is this because I'm rooted or a problem with the update? Thanks.
