Wii totally bricked

I have a WII with 3.2E and no Modchip. I have HBC.

I deleted by mistake the IOS30 through WAD Manager. I know, I f*** up...

Now the WII is totally bricked and I can only see a back screen.

Can you help me to unbrick my WII? Will the SaveMii work or no?

Savemii will not work. Your last hope is Infectus, Bootmii and Betwiin. If that's too hard, then try Nintendo's repair.
