I do an unbricking service. I will remove the nand chip and program it externally. I have unbricked well over 200 wii's. As anyone on this site will tell you, I am the man to send your wii too if you don't want to purchase an infectus or if you don't have shit for soldering skills and tools.
Unfortunately, if your wii has a samsung nand flash chip then it MUST be removed from the wii's motherboard to be able to program it. That requires a hot air station.
