Hi, im not sure, if it works on Your TV, but if You want boot from external source, You need enter commands in bootloader prompt from u-boot menu (BOOTROM DEBUG SESSION), not in debug console ([ TOP Debug Menu])- as You made. Steps 5-8 are not needed for booting from USB exept command line on step 8.
To enter bootloader press ~ (shift+` on keyboard) and power on TV. Look on
Wiki. After You see "Hit any key to stop autoboot: 3-2-0" you must quickly pres Enter. You should see smth like:
Code: Select all
U-Boot 1.1.6 (Dec 12 2008 - 15:55:34)

SELECT COMMAND:
press "0" and here, just here You be able to enter command (from Your step 8) to boot from USB. I cant say is that command line good for booting Your TV, i bootet my B653 with it, everything was ok. But i don`t know if is god for Your TV.
