    Ok, FINALLY got good compare results.

    Stripped off all the wiring and cut some fresh from the reel.

    As I said, the file you sent me matches the beginning of my infectus dump 100%, but when I flash blocks 0-7 bootmii still doesn't fire up, although the fan spins and I can turn the machine on with the wii remote.
    I've tried 2 different SD cards, both of which I'm positive work (checked in another console)

    Should I be only flashing blocks 3 & 4?

    Also, does anyone know if the Willem supports the Samsung K9F4G08U0A? I have access to one...

    The file I emailed you contained boot2v2, you probably have a higher boot2 installed in your wii and then it won't work. I will send you the same blocks with boot2v4 installed. Try that one. That should work, if not then you should try a component cable.
    Happened to me before, kept flashing all kinds of bootmii nands and it turned out that composite out was broken.
    I will also try adding capacitors to data lines and ground will post back results

    As I said, the file you sent matches the NAND dump I took from the Wii 100%, so I'm guessing it's boot2v2. The NAND dump taken from my working Wii is Boot2v3 and has quite a few differences & doesn't have bootmii installed. But from what i understand, the Wii should load the Boot2 if it's equal or higher version.

    I'll give it another go. Thanks Erikie

    Thanks for the great tut and.. I have a problem :)

    Hi Erik,

    Since you helped my friend Ferid out so well, I hope you can give me some pointers as well

    Have a Wii here which has been 'intro-movie-bricked' (don't know what else to call it). Owner wanted a custom theme and all it does now is start up, you see the movie instead of the Health Screen and it crashes.

    So, I wired the infectus2 in and programmed the infectus2. Then did a few full dumps. I noticed the first blocks were all FF's. I tried a few more times (varying the time I grounded D0) until I got a few dumps which had no FF's in the start and does were both identitical.

    Compared it with a boot2v4 with bootmii I have. (I know it's correct, since Ferid used it on his). In your tut you say the first 200-400 bytes should be the same. Well.. they weren't, more like the first 48 were the same, then it varied a bit. Anyway, since I have a complete dump, I might as well toy around a bit.

    So I wrote that boot2v4 with bootmii according to your tut. Now, with testing (I hooked a lot back up) the drive doesn't respond, the led stays blue and the tv receives no signal (tried component and analog).

    Is this due to the fact that I have the wrong bootloader ? I thought that boot2v4 is always good ?

    Hope you can help me out. If not, no worries, still appreciate your tut very much

    Hi mate. Where abouts did you solder your infectus to? The VIAs or directly to the chip?

    If you're getting FF in random places, try as erikie suggested and use longer wires for the Q point & also use 3 or more GND points. This seems to have helped with mine. I didn't even have to GND D0 to get the dump. I have also attached capacitors between D0-D7 and GND to eliminate 'ground bounce' - these are 0.01uF ceramic caps (decoupling caps)

    I've also noticed on the underside of the Infectus 2 PCB there is a small GND tag - Try attaching this to the GND on the Wii motherboard. If you ever use your infectus as a modchip for the wii drive, this point MUST BE connected otherwise you end up with sync issues (drive won't spin)

    If the first bytes do not match then you have a different boot1 version and the bootmii injection does not work. Hence the blue light that stays on. Boot1 is not the expected version and the wii will not start any further. If the blue light flashes then boot1 is read and OK according to the hash in the OTP area.
    The only way to fix that wii is with a bootmii backup or another backup.
    Flash back the boot1 (first block of the nand backup) and your blue light should be ok again

    Hmm, that's a bummer. Since I only have a boot2v4 and I thought that was a one for all solution (guess not), do you think a boot2v2 would solve it ? (of course I can flash back the boot1 of the bricked wii dump, but that only brings me back to square one (for problem determination I can understand, but I'm going to take your word for it ).

    Thanks for the swift response !

    edit : the Wii is a LEF120xxxx series. Don't know if that is important (boot1 version ?).

    LEF120 is not fixable, boot1c is in there. Boot2 is not important.
    Boot1 version is the key. If boot1 is not boot1b then there is no option to fix the wii unless you:
    a) have the keys of your wii from the OTP area
    b) have a nand backup (working or not does not really matter as long as you have the KEYS of your wii)

    So your wii is good for spare parts or keep it untill some one finds a way to fix those too
    I have a stack of mainboards at home that have wrong boot1 version

    Ok, that clears it up then. Anyway, it was a good exercise, I never soldered that much to nands in the past and the fact that I succeeded (thanks Ferid ) the second time around is enough gratification for now.

    Your tut still stands !

    Thanks,

    Why not sticky this in one of the appropriate forum? ALOT of us have wii's with vulnerable boot1, and alot have a low-level brick wii.
