I tried downgrading to Froyo to root, and I did the adb processes, yada-yada. Followed the guide to a tee, and then during updating, it got stuck midstream. I HAD to pull the battery, as it was taking way too long to finish. I turned it back on, and stuck at the splash screen. I'm able to get into H-Boot, however, so there may be some hope. I tried redownloading the PD15IMG file and retried. Same nonsense. On the sides, where it shows the progress, it says "Fail."
My problem is similar. I attempted to change out a cracked digitizer on the Glacier and encountered this problem. The phone works fine until I attempt to tighten the screws on the main antenna. When I do so, the phone boots into a frozen HBoot screen. Nothing happens when I press the up, down, or start buttons. Also, I am unable to use any of the buttons.
When I loosen the screws, it boots in normal fashion and the buttons and all work normally.
Does anyone know the answer to this problem?
