    Sounds interesting. In the case of a full brick where the system menu ios was deleted, what would it use to launch things? Are you referring only to semi bricks I assume? What system menu did you do this on? I'll be following your updates. Best of luck!

    Lots of testing still needed however the idea is to be able to autoboot this disc with a modchip and unbrick just like UUDv4. The difference is that I will most likely keep dop-mii as the unbrick app instead of wad manager. The best part about this disc is it doesn't require any softmods or custom IOS (edit: it does require patched system menu IOS to be installed to run.) This means it should be able to recover just about everything including full bricks as long as the recovery menu can be accessed with an autobooting modchip installed. I will keep this post updated during testing and will post back with all results. The initial testing was done on system menu 4.2U.

    **EDIT: After testing on three other consoles, I found that it only worked on one other and failed to work on the other two so I did all the cvs reports and compared. I regret to post this but I think that I did in fact get ahead of myself here as it seems that both the Wii's it worked on had a patched system menu IOS. After removing the system menu patches I've found that the disc will not load. This doesn't make much sense to me since I have not trucha signed any of the files in the partition or on the disc at all for that matter. Also, I have made many other versions of this and non of the others worked at all until I patched the main.dol with the correct encryption. e.g. If you just insert the non patched dop-mii dol file into the game partition, it does not work even though the system IOS was trucha patched.

    Sounds unlikely to even be possible, as by changing anything in the file you are going to make it fail Nintendo's checks, unless you have a Trucha IOS.

    But happy to be proven wrong.

    Believe me, I've been told that by a lot of people during this process and have had much failed attempts. However, the wii recognizes the file change because the partition has its own title key. This key is stored in the partition, in the ticket.bin. The wii checks all the files in the partition against this key which I used to patch the dop-mii main.dol. I then injected the patched main.dol into the decrypted partition and encrypted the entire partition with the common key which is used to encrypt all wii games. Current programs like trucha signer and wiiscrubber all ready use the common key to decrypt a wii iso.

    I'll get the main.dol and instructions up tonight. I can use some help testing this. The only other thing I can say is that it does load dop-mii as described and I didn't trucha sign anything. I will check all the ios on the wii to make sure there are no trucha patches present. This wii came to me with nothing but a black screen at boot up.

    Happy to test anything, I have plenty of Wii's I can setup in various states of bricked/system menu/etc and can recover even if it all goes wrong.

    Bad_Ad - Go for it, I need all the help I can get.

    On a bad note, I Just tried it on another bricked wii and so far no luck getting it to work. Sh**!! Here's a video of it working on my other wii take a look. I completely softmodded from this disc.

    Here's the patched main.dol to replace the existing main.dol file in the game partition on NSMB.

    Just get NSMB iso if you don't all ready have it.
    Then use Wiiscrubber to replace the existing main.dol with the patched one in the main game partition.
    Then right click on the game partition and click on unencrypted partition and then click save
    When that finishes right click on the game partition and click on unencrypted partition again and then load. Load the partition you just saved back into wiiscrubber.
    Once everything finishes burn the nsmb iso to a dvd-r disc. (I used a sony dvd-r)

    I will post more detailed instructions once I get all my testing finished. I also need to find out why it's not working on this other Wii.

    Looks very promising, well done. I never imagined something like this would be possible but here it is in front of my own eyes! Perhaps this is something we can consider using to recover all those error 003 wiis...

    Keep us updated, & once again well done!

    Still sounds to me like you have trucha IOS's on the wii it worked on. The fact that you were able to use an IOS in dopmii straight away shows you have old/patched IOS's.

    If you didnt, dopmii would complain and make you downgrade IOS 15/36.

    This is exactly what has already been done in the korean 003 thread, but again it relies on you have patched/old ios's.

    I will test what you said on a freshly formatted wii with 4.1 installed from a disk.

    Maybe you should run syscheck & post the report here just to make sure you don't have any trucha IOS. I'm not being sceptical or anything, but maybe it might be a good idea just for the sake of confirming or proving wrong our fears.
