How To Unbrick Your Wiz (Retail Wiz - V1.1.0 Firmware)

Eh, I was hoping that wasn't the only option, that guide seems way over my head. Well, the thing lasted a good 30 minutes unless I can do something using only the included USB cable or if I can get my friend who is more used to getting physical with his electronics to help me out.
Thank you so much for responding quickly though. I might've tried that out though myself had I the appropriate equipment already.
