I am attempting to load a UF2 file into an EV3 robot, however when I plug everything in, nothing appears. Windows recognises that a device has been plugged in, and it even appears in the Device Manager, however it doesn't point to a file folder.
This is from https://makecode.mindstorms.com/troubleshoot
Check that you have the newest firmware; on the EV3 brick:
Go all the way to the right to the wrench tab
Go all the way down to the menu called 'Brick Info'
The information dialog that appears should say something like:
Brick FW: v1.10E
If you have a version which is less than this, then you need to upgrade. Unfortunately, this can only be done from the very buggy EV3 Manager at https://ev3manager.education.lego.com/
