[RELEASE] Haxchi PC Installer (for 5.5.2 with SEEPROM backup)

image.jpeg

This tool is for v5.5.1-v5.5.2 only (because of the HBL loader). OTP and SEEPROM are required, so it is only for previously hacked consoles with backup of those files. (If you installed redNAND before you should be able to dump those files from your SD)
(If you don't have OTP you can take the OTP from someone else because the USB key is the same).

This tool is very experimental, USE AT YOUR OWN RISK.
This tool is based on WFS File Injector.
Credit for @FIX94 for the Haxchi and for @dimok WFS Block Injector for the inspiration.

Instructions: (READ FIRST)


Preparing the USB
  1. It is recommended to use a clean USB and format it for this process. The installer is expermintal and may corrupt the file system.
  2. Buy and install one of the supported DS VC games, and move it to the usb.
Installing
Choose one of the following methods:

Method 1: Direct install to the USB (faster but more risky)
  1. Connect the USB to your PC, and find out the drive index:
    Open PowerShell (WinKey + R, enter powershell)
    Run the command
    Code:
    Get-WmiObject Win32_DiskDrive
    Find the DeviceID for your USB (Example: \.\PHYSICALDRIVE3)
  2. Open command line with admin privileges (Start Menu -> Search for "Command Prompt" -> Right click wnd "Run as Administrator")
  3. Go to the directory with the tool:
    Code:
    cd <where you extracted the files from the zip>
  4. Run the installer: (Don't forget to replace \.\PHYSICALDRIVE3 with the correct device)
    Code:
    haxchi-pc-installer --image \\.\PHYSICALDRIVE3 --otp otp.bin --seeprom seeprom.bin
    And follow the instructions.
Method 2: Install on an image (safer)
  1. Dump an image of the USB device with tool like Win32DiskImager.
  2. It is recommended to backup the image.
  3. Open ccommand line (WinKey + R, enter cmd)
  4. Go to the directory with the tool:
    cd <where you extracted the files from the zip>
  5. Run the installer:
    Code:
    haxchi-pc-installer --image <dumped image file> --otp otp.bin --seeprom seeprom.bin
    And follow the instructions.
  6. Flash the image back to the USB.
Finishing
Now just connect the USB back to the Wii U. If you run the game HBL should be opened instead.
Now with HBL access it is recommended to move the game back to the NAND and reinstall haxchi again with the regular Wii U installer.

I'm pretty sure that this is an haxchi error...the exploit injection is fine...
Actually, it seems to either be trying to launch a payload that isn't there, or his SD isn't even in the Wii U.

Was your SD card in your Wii U? If not put it in. Haxchi also could be looking for an app that doesn't exist, like fw.img, or the Homebrew Launcher.

He means of course that haxchi-pc-installer.exe is not there (you can do it with wfs-file-injector.exe but the other one does it automatically)

Anyway @GrandZeldaGamer I uploaded a new version.
i found the command to make it work on my own with a bit of help from someone on another thread and it works

@GrandZeldaGamer can you share the command, thx
@yoppie what VC game are u using and what is your consoles region this info is needed
here's the command for European brain age and some info as well
READ THE INFO FIRST!
wfsdump --image usb.img --inject-file rom.zip --inject-path /usr/title/00050000/10179c00/content/0010/rom.zip --otp otp.bin --seeprom seeprom.bin

You actually need Haxchi rom.zip file, and also inject-path must be changed to fit your actual game and region.
