Metro M4 Grand Central not working
I managed to upload two different sketches to my Grand Central M4 (ordered via DigiKey) and it now cannot be recognized by my computer. Resetting it doesn't work and I've verified that it is not the cable or my computer. Any advice on how to solve this?

Can you double press the reset button to get into bootloader mode and see the BOOT folder?

I can do that, yes! Though I'm not sure how to restore it to its original state (before I uploaded the offending sketch)

Leave it in bootloader mode and try uploading a basic Blink example sketch to it.

Re: Metro M4 Grand Central not working
Cool. Glad that worked. This can happen sometimes. It's generally something with the last sketch that was uploaded, which then does "something" and prevents the board from being reset from the Arduino IDE to accept a new upload. So the work around is to manually go into bootloader mode and upload a known working sketch, like Blink. So if it happens again, that's your recovery process.
