Brains Dead after vex IQ 2.1.3 update

Ever since I update my Vex IQ brains to the newest version, the computer no longer recognizes them. When I plug in the USB to micro cord, nothing happens. If I plug in an un-updated brain, it says the it is connected and lets me download my code. I have 5 dead robots that I cannot use right now. Only the brains with the older firmware work. Any solutions?

Which programing environment are you using ?

One thing to try… after updating your Brains to VEX OS, you may need to go to “Settings” -> “Erase User Programs” on the IQ Brain to see if it can resolve the issue.

i have this same problem but my brain came 2.1.3
