So I tried to update my phone from home a few days ago. It didn't work. I got to the Volume Down+Camera+End step and plugged in the USB and it said "USB device not recognized." Something like that. I tried for about an hour, restarting PC, toggling USB debugging, and turning off the phone. After that, I got fed up and deleted the update software from my desktop and told my mom to take me to Sprint next weekend. Any similar problems?
