Inserted usb flash into TV and started update using source / pwr button.
Still waiting as it reads "SW upgrade - upgrading - Do not detach USB equipment"
I made sure the USB Flash (2GB) was formatted to FAT32 first so wondering now what to do... its taking too long seemingly....
I left the 1007 file loose on the USB flash drive as well as putting another copy in the folder (just in case).
This time (second time around) the turquoise update bar came up. The TV went off and the red LED just blinked at me repeatedly. I turned the set on and checked the firmware version in the Menu>Setup>System and its still 1006....
