I got the blue FASTBOOT screen on my ally today... Everytime I tried to reflash to the factory rom I couldnt because I couldnt get to the menus to do it. If this happens to you dont panic! You have to hit the power on button to turn on the phone right? Well the Ally has that mostly annoying feature that when you plug it in to charge when it is off it turns on! I was freaking out and then when i plugged it in to charge it... Fired right up! Wow... So that annoying feature actually saved my phone today!
