    Hardware Wii U Fan Wires Color Diagram (Help)

    No idea if this will help anyone but I just fixed mine by replacing Q5. It's marked with B2, with a line above the B. Not sure what exactly it is as I was able to scavenge the part off a donor board.

    Tutorial How To: Upgrading / Rebuilding Wii U Internal Memory (MLC)

    Hi all, wanting to use this to fully rebuild a system's MLC, but have one important question: is the RPi Pico removable after this process, or does the new MLC depend on the modchip being permanently installed?

    GCN Possible GameCube IPL exploit vector?

    I'm just a fan of the idea of softmods in general, where anyone can hack a system without actually physically modifying anything and it's completely easily reversible if you want to sell it on later. Stuff like the GCLoader is neat since it's easily reversible, but there's just something cool...

    GCN Possible GameCube IPL exploit vector?

    Exactly, this is the kind of exploit I was searching for. Unfortunately, most of the memory card reading code seems to be quite robust and I couldn't figure out a way to exploit it besides that one switch case oversight.

    GCN Possible GameCube IPL exploit vector?

    I'm talking about softmodding here, where you can run homebrew and everything without having to open up the console or solder anything. I know that installing modchips and such is fairly easy but softmodding has always been of interest to me.

    GCN Possible GameCube IPL exploit vector?

    I'm new to security researching but have always been interested, so I recently dove in to try to reverse-engineer the GameCube's IPL and see if a gameless softmod is possible. Even though I don't have much experience in this, I managed to find something that could be exploitable, though I don't...

    Hacking Decrypting/re-encrypting MLC to "clone" donor Wii U's MLC

    Unfortunately trying to inject files tends not to work on mine because the allocated space for them is too small (or something, it's been a while).

    Hacking Decrypting/re-encrypting MLC to "clone" donor Wii U's MLC

    Oh hi, glad to see you here! It's unfortunate we don't yet know enough about the filesystem to be able to achieve what I want. I couldn't figure out how to inject files manually when the file it's trying to replace is corrupted or just gone from the filesystem, so I thought maybe a brute force...

    Hacking Decrypting/re-encrypting MLC to "clone" donor Wii U's MLC

    Finally got back to this project, and yeah that command seems to work for decrypting it, at least partially. It also "decrypts" the blank 00 bytes into garbage data, so I'm guessing that's screwing with re-encryption, or at least part of it. We really need to figure out how wfslib determines...

    Hacking Decrypting/re-encrypting MLC to "clone" donor Wii U's MLC

    If you're on Windows, you can use the Visual Studio solution file... though I did I have to fix it to work on Windows 10. I can share my fork but you'll have to get cryptopp yourself and build/point to it, since the latest version isn't on nuget anymore: https://github.com/Sierraffinity/wfslib

    Hacking Decrypting/re-encrypting MLC to "clone" donor Wii U's MLC

    I actually fixed that issue in my local fork, but I don't want to traverse the filesystem itself, so that shouldn't matter. Or is the encryption on a file by file basis and there's no other way to do it?

    Hacking Decrypting/re-encrypting MLC to "clone" donor Wii U's MLC

    Yeah, unfortunately it's not a thing I can do in the system's current state. Thanks though!

    Hacking Decrypting/re-encrypting MLC to "clone" donor Wii U's MLC

    Oh yeah, forgot to mention, the Wii U wasn't fully bricked before I reset it, so I was able to dump everything (but the MLC, which I got through the hardmod eventually). So having the keys to decrypt both MLCs isn't the issue, thankfully.

    Hacking Decrypting/re-encrypting MLC to "clone" donor Wii U's MLC

    Hi all, So, bought a Wii U from eBay, came with the wonderful 160-0103 issue (not from CBHC though, the MLC itself is corrupted). Reset it to stock and now it's completely bricked, as booting goes straight to the same issue. Well, since it's already broken, I guess I can't break it any further...
