Flashing bios without usb cable


Recommended Posts

Is there a tutorial available that details how to flash the bios without using a USB cable. When I plug in the Harmony cart via USB my PC doesn't recognize the device. I've tried downloading the drivers and following the instructions from the forum, but it still doesn't recognize the cable. I'm asking because my cart stopped working a few months ago and I believe it's because the system was turned off while the cart was loading.

If the cart stopped working, you must flash via USB. Direct flashing from SD card requires a working Harmony cart.


You should try different cable, many are only meant for loading , but you need a data cable here.

Ok thanks,


I've tried 2 different ones but they are probably meant for charging only. Could you recommend a good data cable. It's kind of hard to find a tarnsfer cable with the outdated mini USB plug.
