Can't get 2G in DFU mode and it keeps rebooting
i have a serious problem with my iphone 2G (it's currently on 2.2.1). i can't get it in DFU mode. i have already jailbroken an iphone 3G so i know how to do it but with this 2G it won't work.
I also can't get to the menue screen. there is no slider for unlock just for emergency calls.
Another thing is that everytime i unplug it from Itunes i can't switch it off it just keeps on rebooting. And i can't turn it on once it is unplugged.
Everytime i try to get it in DFU mode it switches to the black screen but it won't stay black, the aple log just reappears.
Do you guys have any idea what might be the problem or is it just broken?
