========================================
I had not activated the phone with the carrier TMobile but had a new sim and was updating to transfer the line from my old phone. I decided to do a factory reset and now it's stuck in the "fastboot" mode and the logo "powered by android" Tried vol up/down and power hold nothing works. Can this phone that was never used be salvaged?
