How Force load the factory (or any other) bin file....

Load the factory bin to your usb stick.
Insert the stick and shut the box off from the rear switch.
While holding the "Menu" button in on the box, restart from the rear switch.Hold the "Menu" button for at least 5 seconds when you boot from the rear.
This will put the box in USB mode and you can use the buttons on the box to navigate and force load the file.When your in usb mode,"USBL" will be displayed on the the box.
Restart as normal and load the current file for your box .
If your on component video, you'll need to downgrade to standard video (yellow output) to see the Usb mode screen.

Good luck,
