mafranklin:

The firmware file you have is correct for N810 WiMAX Edition.

Where/when did you get your N810WE? If it is a "pre-production" model, the "COMBINED" firmware will not load to it. You'll need "LEGACY" version, which I'm afraid is not available for general public...

EDIT: It is actually other way around... If you did have pre-production model you can flash the firmware, but on final release device it will not work due to bootloader being incompatible with the hardware ID. New firmware release is expected soon to fix this.
