I get " Failed to boot 4; Starting RSD Mode" and that's it... I have pulled the battery several times, tried to do the reset where you hold down the volume down button and hit power, but the phone just turns off after about 30 seconds. The only way I can get it to stay on is plugging it in on the USB cable and then it goes to this error. HELP! I got the message that there was a software update available and now it's dead dead dead!
