My second Photon was bricked this morning. I was using the hotspot and usb tether to download music. Suddenly it got caught in a reboot loop. After several battery pulls and a factory reset the phone displayed an error page. This page said that the modem would not power on and that it was in some recovery mode. I tried another few battery pulls but no matter what I got that error screen. When it was displaying the error screen it wouldn't even let me power it down with the power button. It was just bricked. I just got back from Best Buy. I exchanged it for my third MoPho in a week and a half. Hopefully MoPho number three is problem free. If not, I might be done with the MoPho.
