Hacking DumpsterU - Wii U Harddrive Dumper

[jeannotte]

Hello ,

@ GaryOderNichts:

I congratulate you on your hard work.

I just tested version 1.0.1, it works very well for me.

fast, clear and precise transfer

Great work. Something i would suggest to add is an option to pack the files to installable format (after transfering the unpacked files) and delete the original files afterwards. All you will then need is the tickets for restoring your hdd.

This would be a great idea! To make backups of our games!

Also batch backup function

Nice work.
About modifying the file system - I actually got pretty far in researching the file system (I am looking into it from time to time). I figured out how the blocks allocator work, all the internal structures and allocating code. But the part that I haven't figured out yet is the journal (which apparently this file system has). Maybe it will work to modify the file system without updating the journal but I am not sure if it is a good idea. There is a lot of code related to the journal so this is why I haven't completed my research yet (and I haven't looked into it lately)

Oh hi!
You're still alive
Thank you again for all the research you have done.
That sounds awesome. Creating new files would make many more things possible.
Maybe I can help you with some stuff?
I'm not sure if I could help that much though, since I have many other projects and personal things I'm currently working on.
I'm most active on discord (Gary#4139).

From the screenshots it seems that titles have to be dumped one at a time.
I believe that an option to dump the entire filesystem would be useful too. That would pave the way for using a fat32 formatted hd via mocha_fat32.

 

[XDeltaOne]

Can somebody further develop Mocha fat32 or make it faster?

 

[SuperDan]

This is pretty fucking cool !!!! thanks alot i will be using this !!!!!!

You can dump the entire filesystem using wfs-extract:

There isn't a GUI for it though.

Is there a way for my PC to detect my Wii U hard drive? For some reason, my PC won't detect it without formatting it.

Excellent app, thank you very much for this amazing tool

Is there a way for dumpster U to detect my otp.bin and seeprom.bin because for some reason it won't detect it! It says "Error, Not a WFS Device or bad key."

Hello,

GaryOderNichts said this about his tutorial:

==> You need a OTP and SEEPROM backup from the console the harddrive was formatted with. You can get the backup with Wii U NAND Dumper.

Is it possible to use this to dump encrypted games ready to install with wup installer?

 

[The Real Jdbye]

Surprised I haven't come across this thread until now. This is a really useful and much needed tool since there were only very limited dumping options for WUFS before. Surprised to see any devs still working on the Wii U, but it's a good thing.

 

[GaryOderNichts]

No since you can't dump tickets from a hard drive.
You can repack them fakesigned with NUSPacker though.

I have an older Wii U formatted USB drive which content I'm trying to dump, but couldn't succeed. Also the Wii U – where this drive was formated – doesn't recognize it. Could this be because the Wii U system was factory reseted in the meantime? Does that affect USB storage encryption?

Yes. The SEEPROM changes every factory reset. I think that it is just a sequential increase. So if you can dump the current SEEPROM, you can recover the previous SEEPROM.

you have to decrease the value of that byte by one.

there's a two-byte change with the seeprom with every dump, which I don't understand. I'm aware of the sequential change, but this doesn't really make sense to me. I don't know what the two bytes do, but those are the only changes.
