Yesterday, my rooted Xperia Pro decided to go into perpetual restart mode. I tried removing the SIM and SD cards to no avail. I tried reflashing the ICS upgrade. I tried throwing my phone across the room. (Well, OK, so I haven't tried that yet.)

What exactly happens

  1. I turn on the phone.
  2. The Sony logo comes up.

    Sony Logo

  3. It lights up for 1/2 of a second. I cannot get into recovery mode ever since I reflashed the ICS upgrade.

  4. The Xperia logo comes up.

    Xperia Logo 1

  5. The phone vibrates very briefly. (Like a haptic feedback vibrate.)

    Xperia Logo 2

  6. The lockscreen used to flash for one second before I tried reflashing the ICS upgrades. Now, it just shows a gray background with the status bar.

  7. The phone reboots one second after the status bar appears.

Other information

Recently, my battery would randomly go from 70% to near 10% in a few hours or so while it was in my pocket. (As opposed to the regular 1%/hour rate.) Sometimes, it would open up the status bar or unlock my lockscreen. I had an OTA notification in my status bar -- it's possible this might have been selected accidentally.
