I am attempting to upgrade my ROM from the 1.7v. I dl'd the RUU file and did everything as required. However, when the bootloader tries to connect I get a prompt, "ERROR:USB Connection ERROR". It asks me to make sure that the phone is connected to the USB cable and for the USB cable to be connected to the PC. Both are connected but I noticed that the phone is powered off. It will not power back on while connected. It will once I disconnect it from USB cable. This leads me to believe that the phone starts to do what it is supposed to but somehow disconnects. Any ideas?
