Actually, diags has a different menu item for changing board id and serial number. Perhaps when the code broke from a missing ENABLE_DIAGS file, it jumped into the code that changes the board id and serial number, without requesting user input.

I really wish that uboot was a little smarter and if bad board id, it would give you a serial port option to enter a board id, or choose which board type to initialize from a menu. Of course, the uboot INSTALLED on a k4nt should DEFAULT to initializing it as a k4nt. IMHO...

Even better if diags did not shoot itself in the head when it gets confused...

EDIT: No time to deal with this now. It has the serial port brought out through a slightly lifted spot under the flexible back cover. Later, I will try patched uboot that defaults to hardware init for "k4nt" board type. I did notice that the gpl download .tar.gz files for 4.0 and 4.0.1 have different file names, but both have same size and same md5sum. I just ordered another k4nt so I can continue testing my code instead of wasting time trying to debrick this one. Anybody want to buy a bricked k4nt (serial number and board id both "1"), with serial port?
