Very good, Phantom_p3, you did the correct command and i checked that you flashed the file and the file is stored exactly where i supposed.
You did just one mistake: you saved a screenshot while we need the complete log next time. To save the complete log in text format you need a software like teraterm or hyperterminal (on these tools there is a dedicated function to automatically save the printed text to text file).
But this note was just for the future.
Do you have a working unit? if yes, open it and weld the internal serial line. then hit the following command in order to dump the uboot file to ascii:
md.b 0x81080000 0x48000
Note: the md.b command should be available only if you hit ESC while the unit is booting.
Take the saved text log file, compress it to zip format and upload it somewhere in order to allow me to download it.
Then I will convert the file to binary format and I will send it back to you in order to allow you to flash the broken LB.

Consider that the following may occour:
1) the unit may power off automatically while it is printing the data. Before to do it it will inform you with a beep sequence. At that moment you should connect the joystick and move the lever in order to avoid the automatic power off.
2)some of the printed characters may be wrong due to bad data transmission on the serial line.
In order to avoid such problems it is better if you repeat the process 3 times by saving 3 files, in order to allow me to compare the 3 obtained files and eventually correct some wrong bytes.
