Any ideas about how to fix this.

The phone doesnt register on my computer when I plug it in. I already unlocked it, via a usb cable to run iBrickr. the phone works on my t-mobile, i can use youtube, safari, ect. but now that everything is complete, It wont charge off the a/c adapter or the computer. are there files i can replace or restore that run the USB. maybe they got corrupted? i was thinking a restore, but itunes can't see the phone. one other thing. when i go to put the phone in restore mode, it just goes black, i get an apple, blank, apple, blank. never any triangle.
my first thought would be to put it in dfu mode, is there a way to initiate that via putty or terminal or something?

I thought I saw another thread that talked about this. Problem is, you cannot search using just the letters "USB". You might have to manually look through the pages of threads.
