    Here is another method

    You will need some electronics experience tho, it basically involves a diy nand hardware programmer and some soldering:

    Do you have bootmii installed as boot2 or ios only? If only as IOS then you can brick your wii with a restore. However you can always flash it using a hardware programmer.
    If you have it in boot2 then you can always flash it again

    Restoring a NAND restore with Bootmii/IOS is dangerous. One error and you have a full brick with no way to fix. Better to fix the cIOSCORP fail problem, at least that way you'll have a working Wii, rather than one that doesn't work.
    Not really doing much Wii stuff these days.

    Hey erikie, I've got my infectus 2 rigged up to my Wii as we speak. I have another Wii which has boot2v3 on it but cannot install bootmii to it.

    Do you have any dumps with Bootmii installed I could 'borrow' to fix mine? Please PM me if you wish.

    In regards to reading/writing with infectus... I'm getting a bit of ground bounce. I've doubled the Gnd wires & also made sure all my Address & Data wires are short and tidy, but I'm still getting some.

    Also, which part of the NAND is responsible for the Recovery Screen? Can you not just flash another standard boot2 from a working machine, then boot to the recovery screen and run the UUD disc?

    The trick here is to flash bootmii into the nand. You cannot do anything else to unbrick a wii if you have no nand backup and you need boot1b in your wii for it to work. No exceptions. If you still have ground bounce try a third ground wire or extend the wire to Q on the infectus (WE signal) I use one that is very long and it always works.

    Yes I understand about the Bootmii as boot2 (thanks for your email, really appreciated)

    I have checked the file you sent against the NAND backup i took from the bricked Wii & everything matches EXACTLY.

    In regards to ground bounce, you're saying just use a long wire for the 'Q' point? Could I lift the pin and solder straight to that? (Wii will not have access to WE pin)

    Just take a longer cable. Gives the same result without risking of braking anything on the nand chip. I use a wire that is about 4 times longer. And I use 3 ground points.

    Just been reading up, you can reduce ground bounce with decoupling caps - maybe this could be a future mod for my infectus?

    From what I've read, attach decoupling capacitors (0.1uF or 0.01uF) between the data lines and Gnd should improve signal quality by up to 70%

    Think I might try attaching a small cap between point 'Q' and GND see if that clears the random byte inserting (damn infectus)

    Another thing to put on the 'to-do' list
