My phone was only having reboots every once in a while. I decided to install the 12.24.1 update and now it goes all the was through the boot during start up with no problems. I get to the lock screen and it's just frozen. I can push the power button and the power off, reboot etc screen comes up but I can't select anything. I just pulled the battery and I'm flashing my nandroid backup prior to the update. Any ideas???
