Homebrew [How-to] Load a fw.img for Any File Dumping + WiiUBru status update

[opendata]

I'm interested in the process.

same, if its not in the OTP where is it?

is rednand in its current state likely to brick my wiiu and how do you compile it (is it similar to how you compile this fw.img).

in its current state its not advisable to touch the leaked RedNand with the leaked dumper, not to mention its only useful to devs at the moment due to you not being able to install unsigned titles its basically like running the stock fw to the end user.

Rednand is fairly stable to a certain extent from what I know of, its the Nand dumper that was leaked that is unreliable and dangerous when used with RedNand.

Alright, I've got a stupid question.

Normally, if we want to use mods, we have to use either Loadiine or Cafiine to load them off the SD card. And on the Loadiine side of things, overwriting the "update" folder with whatever you want to change works just fine. So I got to thinking - what if we did this same process, but on the Wii U's version of the files?

I took a peek at the DLC folder on the Wii U using this client, and I noticed that everything is decrypted just like it would be in Loadiine. The md5sums for a file on the Wii U vs something decrypted using CDecrypt even match.

So my question is - can we use this utility to copy mods directly to the 0005000e folder on the Wii U, overwriting old files? What would be the risks associated with this (other than messing up the installation and having to redownload them)? Is there anything on the Wii U checking the integrity of the decrypted update files?

I actually gave it a shot once, but the game crashed, although it looks like some folders failed to copy, so I'm trying it again.

you would either need to sign the files or have the signatures checks of to do what you want to do I think

Yep, looks like it won't magically work the way I want it to . Whenever it tries to load something I've overwritten, it spits out a 150-3032 error, telling me to eject the disc and turn off the console.

I wonder how Cafiine and Loadiine get away with this without any catastrophic errors.

Cafiine gets away with patching files without raising errors by patching the game's memory directly. No errors are raised, because the files on the Wii U/disc itself remain unmodified. In order to install modified files on the console itself, we need to either find a Trucha bug or patch out signature checks using CFW, neither of which has been done yet.

Once we (I mean them) figure out how to patch signature checks, you should be able to enjoy installing your mods as DLC.

Interesting stuff. I figured it wouldn't be that easy.

But ahh, the Trucha bug. It really takes me back. Good times.

Do we know what this would do on a dev unit? Great job guys! ;P

Please help.
What's the cause?　pycrypt's error?

It's probably because you're using the wrong keys.

You can't ask for those here. Sharing keys is against site rules. Edit your post or the mods will do it for you. Google is your friend.

I edited it. I'm sorry about that and it'll never happen again.

I have an error when compiling IOSU. Can someone help me on this? https://imgur.com/a/UjKrC

Do you have Python 2 installed? If yes (Needs to be 2x, 3x doesn't work) go to your computer > system properties > environment variables > select PATH and click edit, then append ";C:\yourphyton2dirhere" without the scores. Mine is ;C:\python27

Open a new prompt and try again.

Also, after that likely your python will complain about missing pycrypto, so open another commando prompt, go to C:\Python27\Scripts and run "pip install --upgrade pip". After that run "pip install --upgrade pycrypto" or "pip install pycrypto".

I already added C:\python27 about 2 days ago.

I gave up after trying to compile iosuhax a couple days after this was released. Compiling anything for WiiU and 3ds on windows is just a nightmare for some reason.
I just found a precompiled version on that iso site and went from there. Maybe some day I'll properly set up a linux environment to compile with but I couldn't be bothered to do that for one file.

Open the Msys prompt and type echo $PATH. Python must show up there.

Yep, Python is there...

echo %path% on the normal windows prompt. If python2 is there and it still doesn't work then i have no idea.

Python2 is there in PATH. By the way, I'm using Python Version 2.7.11.
