I've got an iPhone 2G with the recovery mode loop, tried everything to get it to work but everything fails...

I think I know what causes the problem, but I need someone to explain a part of this iRecovery log:

I think it has something to do with the bold part. Is someone able to explain me what it means?

DFU mode is possible, so is the beginning of redsn0w until the program on the computer says "done" and the iPhone is uploading the ramdisk infinitely (spinning thingy).
