Hacking [RELEASE] WFS File Injector

[EyeKey]

After @dimok released the WFS Block Injector and was able to install haxchi with it, it occurred to me that there is no need to allocate new file system blocks or change the directory tree to install haxchi (which is why I haven't add full modifying capabilities yet).
So I added to wfslib basic editing capabilities. You can change the content and the size of any file, up to the already allocated size of the file on the disk.
wfs-file-injector is a tool that wrap this capability and allow you to inject files.

In the next few days I hope to release an automatic PC haxchi installer, but right now you can do it manually with this tool, just inject the correct rom.zip

WARNING: It is very experimental, and may corrupt your file system. Use at your own risk and make sure to backup the image before.

Usage: wfs-file-injector --image <wfs image> --inject-file <file to inject> --inject-path <file path in wfs> --otp <opt path> [--seeprom <seeprom path>] [--mlc] [--usb]
Allowed options:
  --help                produce help message
  --image arg           wfs image file
  --inject-file arg     file to inject
  --inject-path arg     wfs file path to replace
  --otp arg             otp file
  --seeprom arg         seeprom file (required if usb)
  --mlc                 device is mlc (default: device is usb)
  --usb                 device is usb

Example:
Inject rom.zip

wfsdump --image usb.img --inject-file rom.zip --inject-path /usr/title/00050000/101c3500/content/0010/rom.zip --otp otp.bin --seeprom seeprom.bin

Amazing work, props to you and @dimok

 

[dimok]

Nice work again @EyeKey! My tool became obselete very quick .

I created an automatic tool to install haxchi: https://github.com/koolkdev/haxchi-pc-installer
I will open a thread on it once I will know that it works. Can anyone test it? I tested the wfs modification, but I can't try the usb on my WiiU right now.
Usage:
haxchi-pc-installer --image <wfs image> --otp <opt path> [--seeprom <seeprom path>] [--mlc] [--usb (default)]

Nice job

So to use this I need the otp.bin, seeprom.bin dumped from before I updated to 5.5.2, correct?

Anyways nice work!

Other than the usage message in the program, a minimal test seemed to work properly. Thanks!

Here is how I tested, since it wasn't a perfectly clean test (but probably good enough for what you're testing here):

Inserted a small (256MB) flash drive into my WiiU 5.5.1 US console
Allowed the WiiU to format it
Ran existing Haxchi sysmenu
Opened HBL channel
Used WupInstaller Y Mod to install fake-ticketed Kirby CC (USA) to USB
Shut down WiiU
Imaged drive on PC using Passmark ImageUSB (probably better choices out there for that)
Removed ImageUSB header block from image using hxd
Ran haxchi-pc-installer with parameters per your instruction
Kirby was detected and confirmed
Copied the image back to USB with ImageUSB
Booted WiiU with USB inserted
Ran existing Haxchi sysmenu (for sigpatching)
Ran Kirby
HBL started

This is great, especially for those with slow internet connections (like me) that struggle to handle ftp transfers. I'm on 5.5.0 right now, i already have haxchi installed, i would like to update but don't want to lose homebrew access. just in case my haxchi ever become corrupted, will i be able to re inject it back once i'm on 5.5.2 or do i need something else?

You need your otp and seeprom. The injection isn't tied to any OS version since it's done on the PC. Dimok's injection worked on 5.5.2 so this logically should as well.

I see. Considering that i have haxchi, should i back it up now, or update first?

Get the backup now, and don't update unless you have a good reason to.

ok thanks, i got a little confused and thought that with this tool was safe to update

it's safe anyway if you have haxchi/cbhc

OK, I'm on vanilla 5.5.2, but I have my seeprom, OTP, etc. backed up to my PC. What steps do I follow to test this out?

EDIT: I'm attempting to build the image for my USB but I'm getting a [Unexpected WFS version (bad key?)] error. I've also tried fixing the SLC and SLCCMPT files using NANDfixer, which creates new "fixed" files but I'm still getting the same error with those. Anything else I can try?

Also I'm a bit foggy on what I need to do with the .nds files. I have a purchased copy of Brain Age I can use but I'm not sure what to do with the files that are in the /data folder (if anything.)

Thank you for testing.


And for those who downloaded this tool, I found some bug that may cause corruption to the file in some rare cases (probably didn't happen to anyone), so it is recommended to download the latest version. (Hopefully I got it right time time)

It is possible to install a game from pc, like it were installed by WUP Installer? Kinda like you can do with Wii Backup Manager on the Wii?

I am getting a similar "Not a WFS Device or bad key" error message after selecting the opt.bin & seeprom.bin which I got from my SD card after using Nanddumper. Any suggestions on how to proceed?

 

[SDIO]

what is the command you are running?

 

[punkjah007]

I was following this guide. I didn't run any commands.

 

[SDIO]

then how did you get that error if you didn't run any command?
