did root tonight and all went well. Last thing I did was a baseband update. but I did not clear cache/factory reset, and I had done a ROM backup earlier. all was fine and dandy. was using phone. testing speeds. 45 minutes no problems. Then I tried to go into ROM Manager and it kept closing. So, I just rebooted now is stuck on the M. I have not waited super long as normally it boots right up. if I hold the X at startup I get a yellow exclamation point and triangle with a droid. WTF happened? any help here?
