When I try to update my firmware from v1.01 to v2.02 with universal control I receive the message within my title on the scribble strips. The window showing the update on my computer will actually complete and say it was successful, but it hasn't actually worked. I dont have any other usb devices plugged in. Thanks.

DFU is Device Firmware Update.

This can happen due to connection interruptions or bandwidth issues.

There isn't alot to go on, but if you update over a USB 3.0 connection and with good internet you should be able to remedy this rather quickly.

Restarting your computer can help. Also try different USB connections. Avoid HUBS and Extenders as well. They could cause interruptions in the Data flow.


If you continue to have issues Updating due to a DFU error It is recommended that you reach out to Tech Support for further Troubleshooting.

Update: After about a dozen tries and a few resets it seems to be working fine now. Figured I'd reply to myself incase anybody looks up this issue in the future who wasn't willing to try the same thing for hours hoping it would magically work like I did lol. smiley
