"Media Drive Is Not Responding" problem

Sorry, I forgot to mention in my original post that I did the factory reset but it didn’t solve anything. I’m wondering if this was a bad firmware upgrade (not the firmware itself, just that the device didn’t take it well.)

I tried to put the firmware file back on the device hoping it would reinstall it, but it doesn’t because it’s the same version number. Not sure how to force it to reinstall. If I put the previous version file in there will it downgrade?
