Alright so I was booting up my jailbroken 2g and I got to the white screen, i booted it up alot of times before. when I typed "go" in the command prompt it flickered and wasnt white anymore. Now I try to boot up again but when I try it doesnt even go into dfu mode. when i unplug it i hear the ding dong and also when i plug it in i hear it, and when I set it in dfu mode i heard ding dong but then "A usb device has malfunctioned" or something. thanks.
