I have a stock Motorola Photon, not rooted. I have spare batteries, so I run them to empty, install charged one, and charge the dead one on the wall charger. I pulled the dead battery when the phone was powering down like I have done many times before, and when I installed the fresh battery, the initial Motorola logo screeen comes up with a message on top that says Failed to boot 1.
WTF just happened?
