Flash without USB

Hi guys, need some help

How do I flash a box without a USB chip.

Box wont read any USBS, tried all the formats ,different types etc.

I read here before and tried a method where you install the data somewhere in the duo and reboot the box?

Im currently booting up with the old software but flash with new.

Any Hels appreciated.

Thanks

Thanks, i kept looking and found an easier way. I knew I read it here once before!

Simply load you new image to the backupimage folder on HDD or USB and restore image.

Thanks anyhow.
