Hey Guys,

i have replaced the communications board in my iphone 2g, because the old board is defect.

Now, if i try to start the iphone, the display is staying black.
Also if i connect it to the PC, nothing happens.

BUT: I can boot it into DFU mode and restore it until i get the error 1601 in itunes. This is with every firmware.

What can i do?

Sorry for my English
