Well, what now?
I don't have cIOSCORP for obvious reasons, and Krafter said that I need to install a modchip and run a custom disk to launch the Multi Mod Manager, is this the only way I can unbrick my wii?
Ok, that's sweet, but, is it any hard to flash the NAND? I mean, it is something that all wii hackers should know how to do?
There are only a very few people that can do that and I was almost being sarcastic when I said that because I already told you that your only chance to save your Wii is a modchip, but ya it is possible to recover it by flashing boot2 if the Wii is compatible. It will be much easier to use a modchip and that is why I didn't mention it.
If you are curious look here and the Infectus nand flashing guide.
And the modchip option, is that something well known among wii hackers?
And, what are the risks of installing the modchip? and how much $$ does it cost aprox.?
If you get a solderless chip there isn't much risk at all if you are handy with a screw driver and have some mechanical common sense. If you want at chip then look for a Wasabi DX or a Wiikey Fusion. They very quit at bit in price but you should be able to find one fairly cheep. I think I paid $35-$40 for my Wasabi DX. Besides the chip, you will also need a triwing screwdriver to open the Wii. You can get those from eBay or Amazon.
Oh well, and what does the chip does exactly? and, is there a chance that my wii stays bricked forever? (wish that doesn't happen.)
Well you are softmod so there is a very high chance that it can be fixed. For Example, the chip will allow you to load a custom disk to launch MMM. Once in MMM the System Menu can be reinstalled to fix your Wii. But as I said before and I should mention again, that all depends on you having an older drive that is capable of loading DVD-R disk. The newer Wii will not do that.
