Arduino UNO Not Working!

Hello! I'm having a lot of trouble with my Arduino UNO. I tried to make it work like an Arduino Leonardo, but that backfired on me. Now the board doesn't work as a Leonardo or an UNO. Is there a way to factory reset an UNO? Thanks!


I looked but didn't see anything like that. Here's the site link:

There are a few links in the REPLIES over there. Some of them have RESET instructions.

Best option might be to re-load the bootloader.
