[Help!]Brick/Damaged

My wii i got a few years ago, i soft modded it (4.2u) and i finally got it downgraded (3.2u) but i accidently put in a 4.2u theme and now it doesnt do anything. !!I DIDNT MAKE A BACKUP, I DONT KNOW WHAT TO DO, AND NOW I AM DOWN TO SEND IT TO THE SOURCE AND HAVE THEM FIX IT. As people knows 4.3 is out and it is 100% un moddable and i dont want them to add the 4.3 update and they will anyways. I asked if they could fix it but keep it at 3.2u or 4.2u but NOT 4.3u and they said they cant. This is the last Modding place i know where to go and im stuck. Is there ANYTHING you guys can do for me? If it means i send my wii over.

That sound wasnt me, it was someone else.

Download the software, then save it on to your SD card (assuming you have an SD card).

If no SD card then their is not much you can do, and would make no sense why your wii is modded.

Ok nope it didnt work..

Shit man I'm sorry. I don't know what else to say, I will do a little more research on this.
You can't get to any menus or anything? If you can go to Wii Options (should be last page)
and restore it, this will wipe everything, including internal memory. So try this if it doesn't work
let me know. 'Reformat Wii System Memory'
