    Corruption happens, you cant just assume its a hardware fault so easily.
    I agree, I'm not assuming it to be a hardware issue I just said I might lead towards that direction. It's odd that this happened without any sofware changes (Yes, I realize corruption happens I'm just trying to think of all possibilities). I thought of the system menu coming up intermittently just like recovery menu as you mentioned however I don't think the OP is really even attempting to get to the system menu at this point. It was also stated that specific games which did autoboot when the brick first happened are not autobooting anymore.

    I guess for me it's really simple to swap a wi-fi module just to rule it out. I realize it's not so easy for others since they don't have a stockpile of parts just sitting around.

    Just try to autoboot a game for start, use wii bootme to set the game to autoboot. Then try to autoboot your mario Kart without doing anything to it except patching it to autoboot. If the Mario Kart will not boot, but other games do, then your Mario Kart iso is no good, dump it again (somehow). You should not need to do anything to the Mario Kart iso except replace the wad in the installer partition, patch the game to autoboot, and patch the installer partition to ios36 or 250. You don't need to save the crypted partition and then import it, this does not fakesign the crypted partition. But you can't do anything if you can't get Mario Kart to boot.

    Mauifrog- I must have a different version of wiiscrubber then you but the one I have absolutely does sign it when you extract and import the crypted partion. I'll send it to you if I have to but i'm 100% positive about this. I say this because it doesn't automatically patch and i'm sure others have copies of the one I have. Been through hundreds of dvds with this program.

    It should not sign it, what if you want to import an official partition? Say an update partition? There is no need for it to sign the partition when you import it, the partition has not been modified. It only needs to be signed when the partition is altered. I am using 1.4, same one found in my guide. When the partition is modified, it fakesigns it. It signs it when I replace boot.dol, it signs it when I replace a wad, with anything extra. When I import an officialy signed partition, it does not fakesign it, unless I modify it after the fact.

    Also, when you run iospatcher, it signs it again.

    OK, so when wiicruber 1.4 replaces any file, it fakesigns the tmp in partion.bin for that partion. When wiiscrubber imports a partiion, it does not sign the tmd in partion.bin of that partition.

    Here is the test, using wiiscrubber 1.4 and an officially signed dump (that I own) of NSMB. I opened up NSMB in wiiscrubber and extracted the partition.bin from the data partition and saved it as partition.bin, then I replaced the main.dol with MMM boot.dol and extracted partition.bin and named it partition1.bin. Then I extracted partition.bin from the update partition, and named it partition2.bin. I then save the update partition as a crypted partition, then imported the crypted partition. Again I extracted the partition.bin from the update partition and named it partition4.bin.
    I then ran my 4 partition bins through md5summer, results below-
    45272955053cafa14b6575a182b69214 *partition.bin
    0071bb269c2197d649b8c149e0e2641e *partition1.bin
    b6741fc87f7a04cf600a256eb4eeb872 *partition2.bin
    b6741fc87f7a04cf600a256eb4eeb872 *partition4.bin
    Notice the partition.bin and partition1.bin are different, they have been modified. Also notice that partition2 and partition4 and the same, they have not been modified.

    Does the security check verify the MD5? As you show in your example the first two bytes are 0 so that would indicate the trucha signature however I thought the security checked the SHA-1 hash. For my tests, the tmd isn't trucha signed when swapping out a file in the partition however it does change the value. I was checking the SHA-1 hash and not the MD5 though so I'll have to do some more testing using MD5summer this time. I highly respect what you say however, I know if I make the Mario Kart fix disc, it doesn't work unless I export and import the partition. I will conduct all this testing tonight and repost. I'm not out to prove anyone wrong here, I just have a great interest in this stuff.

    FYI: Any change in the partition will change the value of both the MD5 hash and the SHA-1 hash.

    I don#t know what it is changing in the TMD, I just know it changed because the md5 value changed. I have also waisted 100s of disks messing with this game and others, if you change a file in the game, it will not load, unless it is being loaded by a patched ios. If you take a game, extract the main.dol and then replace it with the same, it would not load without a patched ios. It should work, with just replacing the file and loading with a patched ios. This has worked for me, and many others who have fixed their 003 error Korean wiis this way.

    I don#t have any wii friendly disks left, so I can#t test anything ATM, but it should be working.

    You can read the TMD hash value with trucha signer if you didn't know that. Also, md5summer doesn't read the tmd, it calculates the hash value of a file on its own.

    Also, to correct you. You can extract the original main.dol from a partition and reinsert it into the partition and run the disc without a patched IOS. If you want to test it out, you simply remove the tmd before extracting the main.dol then reinsert the main.dol and then reinsert the tmd. I don't know if you will be able to do the test since you say your wiiscrubber will automatically resign the partition but you can check to make sure the tmd hash stays the same by checking the tmd in trucha signer and then check to see if the MD5 of the partition has changed or not. If the MD5 value stays the same then the disk wasn't trucha signed. I can post a video demo of this later if you're interested.

    OK, so my next attempt will be to set my MarioKart iso to autoboot and trying to load it to confirm that I can at least load this game. Again note that the real game doesn't boot but maybe a autoboot patched one will.

    If it doesn't boot, I will redump it using USB Loader GX and repeat the autoboot patch only.

    Stay tuned.

    That would work, cheater.
