Lovely, thanks for log conversion!
(see, not all of us can afford a msword installarion...)

Now, for the logfile;

1.) First when the device is booted, it copies the menus cpio archive correctly from your mmcblk0p1 so at least that is not corrupted.

2.) The device is booted in maintanance mode, (usb attached) so it exports the partitions out of the device over usb. According to the logs this looks to be OK.

3.) After about 10 seconds you plug the usb cord off, and you should then reboot the device.

Now, can you tell me what did you observe in the computer side of things, did you have some problem mounting the exported partitions or what?
