=<big>Recovering from a CBHC brick</big>=

==<big>Diagnosing a CBHC brick (skip to Requirements if a helper linked you here)</big>==
<big>A CBHC brick is when your console tries to boot to a missing title (the DS game that you used to inject Haxchi into). Here's what happens when you boot a CBHC bricked Wii U (in big lines).</big>

#<big>You press the power button</big>
#<big>Wii U goes through all of its boot stages</big>
#<big>Wii U tries to find the set "home" title</big>
#<big>No "home" title found</big>
#<big>160-0101</big>

<big>And here you are now!... Let's get started for the guide.</big>

==<big>Requirements</big>==
*<big>Preferably a modded Switch or Raspberry Pi Pico (see [https://github.com/GaryOderNichts/udpih/releases supported devices] on the UDPIH page)</big>
*<big>A PC (preferably Windows but I think you can use any OS)</big>
*<big>An SD Card compatible with a Wii U (the one that you should have</big>

==<big>Files to download</big>==

*<big>UDPIH for your appropriate device (see [https://github.com/GaryOderNichts/udpih/releases supported devices])</big>
**[https://github.com/GaryOderNichts/udpih/releases <big>https://github.com/GaryOderNichts/udpih/releases/latest</big>]

*<big>If you are using a Nintendo Switch, please download it using this link instead.</big>
**[https://github.com/GaryOderNichts/udpih_nxpayload <big>https://github.com/GaryOderNichts/udpih_nxpayload/releases/latest</big>]
*<big>recovery_menu</big>
**<big>https://github.com/GaryOderNichts/recovery_menu/releases</big>
**<big>If you don't get any TV output during this guide, please download <code>recovery_menu_dc_init</code> instead and rename it to <code>recovery_menu</code></big>

==<big>SD Preparation</big>==

#<big>Put the downloaded <code>recovery_menu</code> on the root of the SD Card.</big>

==<big>Flash UDPIH to your device</big>==

===<big>If you are using a Pi Pico / Pico 2 / Any supported device that isn't a Switch</big>===

#<big>Flash the appropriate file to the appropriate device. '''This part of the guide will be focusing on the Pi Pico 1 and 2 but any Linux based device with USB emulation should work.'''</big>
#<big>Hold the BOOTSEL button of your Pico while plugging it into the PC. It will show up as a flash drive with the following name: <code>RPI-RP2</code></big>
#<big>Drag and drop the correct .uf2 file inside of your Pico. Disconnect it and it will reboot. '''Do not turn it off from now on.'''</big>

===<big>If you are using a modded Nintendo Switch (vulnerable to RCM)</big>===

#<big>Open any RCM injector of your choice (the most popular ones are TegraRCMGui, JTegraNX and CrystalRCM).</big>
#<big>Put your switch into RCM mode</big>
#<big>Choose the .bin file for your Nintendo Switch and hit inject.</big>
#<big>A new screen should pop up with multiple buttons from a list. To select something, press Power. To navigate around, press the volume buttons.</big>

==<big>On the Wii U</big>==

#<big>Put the SD Card</big> <big>containing the <code>recovery_menu</code> at the root of it. It must be formatted in FAT32. [[Formatting an SD card|Follow this guide to format it correctly]].</big>
#<big>If you are using a Nintendo Switch, it is now time to Run the UDPIH gadget.</big>
#<big>Power on the Wii U. As soon as you see the Wii U logo, plug in the UPDIH device. It may take multiple tries, be patient.</big>
#<big>As soon as the light is purple, you should be good to go. The menu should've loaded but if you get a distorted screen or even no TV output, retry it. If still nothing, download <code>recovery_menu_dc_init</code> as said in the 3rd step of Files to download.</big>[[File:Main menu of Recovery Menu by GaryOderNichts.png|thumb|Main menu of Recovery_Menu.Credits to GaryOderNichts for this screenshot.Click the image to zoom!]]
#<big>Unlike in the minute menu, to navigate, you should use Eject and Power to select/choose an option.</big>
#<big>Select the <code>Set Coldboot Title</code> option.</big>
#<big>You should now see multiple options to set as your Coldboot title (which basically means what you want to boot to).</big>
#<big>Select the Wii U Menu of your appropriate console region:</big>
#*<code><big>Wii U Menu (JPN) - 00050010-10040000</big></code>
#*<code><big>Wii U Menu (USA) - 00050010-10040100</big></code>
#*<code><big>Wii U Menu (EUR) - 00050010-10040200</big></code>
#*<big>If you are on an Australian console, select the European Wii U Menu.</big>
#<big>Confirm the selection if it hasn't been already confirmed.</big>
#<big>Once you're back at the main menu, shutdown the console.</big>

==<big>Uninstalling CBHC after recovering from a brick</big>==
<big>You may tell yourself why you couldn't use the CBHC uninstall guide on the main page.</big>

<big>Well, basically, there's no HBL anymore.</big>

#<big>Navigate to system settings and Data Management.</big>
#<big>Go to wherever Haxchi was injected (generally your internal memory)</big>
#<big>Uninstall the app. '''It is completely safe to do so as you are not automatically booting into CBHC anymore.'''</big>

<big><br />
And there you go! You've successfully unbricked your Wii U and uninstalled CBHC.</big>

<big>You can now format your SD Card following [[Formatting an SD card|this guide]] to delete any CBHC traces. Don't forget to backup anything important.</big>

Wii U:Common key

2025-09-11T10:44:55Z

Acer51: /* macOS / Linux */

=Using a Common Key (Wii U)=

==What is a Common Key for?==
The common key is a key in hexadecimal that is the main way of decrypting things. Every Wii U has a unique one that '''can't''' be changed or modified in any way. It is located in the OTP.bin you are supposed to save once you've made the backup to all your important files.

==How come it is ''that'' important?==
Well, as said before, it is one of the many keys used to decrypt console files. If you find '''any way''' to modify it, you're basically locked out with the wrong key to decrypt your console's contents which means you got a hard brick. That can't be recovered. The OTP is a 1024B file that contains '''all''' the keys to your Wii U console.

==Where is that key located on the motherboard?==
The OTP ('''O'''ne '''T'''ime '''P'''rogrammable key) is located in the SoC ('''S'''ystem '''o'''n a '''C'''hip) of the console which somehow is easily replaceable but you can't write to it... Thanks, Nintendo.

==Any other things I should be aware of?==
In a short way, yes. In a long way, there are multiple other part of the SoC like the SEEPROM, SLC, SLCCMPT and things like that.

In my knowledge, the SLC, SLCCMPT and '''''maybe''''' SEEPROM is writable. There's also the MLC but it is not part of the SoC. It is part of the NAND.

==Why would I need this key?==
Why? Because, for some tools that don't already have a self extracting tool to get your Common Key when redownloading for exemple, System Files (I'm watching you JNUSTool), it can be useful to have it!

Here's non-exhaustive list of all the software that uses the Common Key:

*[https://github.com/stuff-by-3-random-dudes/UWUVCI-AIO-WPF UWUVCI] - Useful for making Wii Virtual Consoles Injects
*[https://github.com/Maschell/JNUSTool/releases JNUSTool] - Useful for redownloading system files

(yes I only got 2 in mind)

==But, I don't know how to extract/get it!==
Calm down. There are 3 main ways for you to get the Common Key.

#Use [https://github.com/GaryOderNichts/WiiUCommonKeyExtractor GaryOderNicht's tool] (Windows only)
#Use [https://github.com/acer51-doctom/commonkey_extractor Acer51's tool] (Windows, macOS and Linux)
#Manually.

===GaryOderNicht's tool===
To use GaryOderNicht's tool, when you open the app, you must click on the Open button, go too the location where your OTP.bin is, select or double click it and your Common Key will appear.

===Acer_51's tool===
To use Acer_51's tool (acer51-doctom on GitHub), it depends on the platform you are on.

====Windows====
Double click the executable. In an explorer window, drag and drop your OTP.bin into the Command Prompt window. You can also manually enter the path to it. Then, press Enter. Once you are finished, press Ctrl+C to quit. '''It will NOT automatically copy and paste.'''

====macOS / Linux====
To execute it, you must open a Terminal window in the same directory as the executable. Then, you must execute this:
chmod +x commonkey_extractor && ./commonkey_extractor
What does this do? Well, the chmod +x is to make something executable and so that you "own" it. && means to do something after this is done. and ./commonkey_extractor is to execute the common key extractor.

After this, the executable with open. You can drag and drop your OTP.bin and the path will be put. No worries, even with quotes, it will still work. After, you can copy and paste the Common Key and press Ctrl+C to quit.

===Manually===
Download the hex editor of your choice. Open your OTP.bin with it.

At byte 0E0 or 0xE0, select the first 32 bytes. Spaces do '''not''' count.
WARNING: You hex editor might select 2 bytes per 2 bytes.

Just a reminder, one letter = one byte.

Copy and paste it and paste it in a notepad window for instance.

And there you go!

== But, I don't know how to extract/get it! ==
Calm down. There are 3 main ways for you to get the Common Key.

# Use [https://github.com/GaryOderNichts/WiiUCommonKeyExtractor GaryOderNicht's tool] (Windows only)
# Use [https://github.com/acer51-doctom/commonkey_extractor Acer51's tool] (Windows, macOS and Linux)
# Manually.

=== GaryOderNicht's tool ===
To use GaryOderNicht's tool, when you open the app, you must click on the Open button, go too the location where your OTP.bin is, select or double click it and your Common Key will appear.

=== Acer_51's tool ===
To use Acer_51's tool (acer51-doctom on GitHub), it depends on the platform you are on.

==== Windows ====
Double click the executable. In an explorer window, drag and drop your OTP.bin into the Command Prompt window. You can also manually enter the path to it. Then, press Enter. Once you are finished, press Ctrl+C to quit. '''It will NOT automatically copy and paste.'''

==== macOS / Linux ====
To execute it, you must open a Terminal window in the same directory as the executable. Then, you must execute this:
chmod +x commonkey_extractor && ./commonkey_extractor
What does this do? Well, the chmod +x is to make something executable and so that you "own" it. && means to do something after this is done. and ./commonkey_extractor is to execute the common key extractor.

After this, the executable with open. You can drag and drop your OTP.bin and the path will be put. No worries, even with quotes, it will still work. After, you can copy and paste the Common Key and press Ctrl+C to quit.

=== Manually ===
Download the hex editor of your choice. Open your OTP.bin with it.
At byte 0E0 or 0xE0, select the first 32 bytes. Spaces do '''not''' count.
WARNING: You hex editor might select 2 bytes per 2 bytes. Just a reminder, one letter = one byte.

Copy and paste it and paste it in a notepad window for instance.

And there you go!

Wii U:Common key

2025-07-10T12:19:18Z

Acer51: Final edit, finished the page

= Using a Common Key (Wii U) =

== What is a Common Key for? ==
The common key is a key in hexadecimal that is the main way of decrypting things. Every Wii U has a unique one that '''can't''' be changed or modified in any way. It is located in the OTP.bin you are supposed to save once you've made the backup to all your important files.

== How come it is ''that'' important? ==
Well, as said before, it is one of the many keys used to decrypt console files. If you find '''any way''' to modify it, you're basically locked out with the wrong key to decrypt your console's contents which means you got a hard brick. That can't be recovered. The OTP is a 1024B file that contains '''all''' the keys to your Wii U console.

== Where is that key located on the motherboard? ==
The OTP ('''O'''ne '''T'''ime '''P'''rogrammable key) is located in the SoC ('''S'''ystem '''o'''n a '''C'''hip) of the console which somehow is easily replaceable but you can't write to it... Thanks, Nintendo.

== Any other things I should be aware of? ==
In a short way, yes. In a long way, there are multiple other part of the SoC like the SEEPROM, SLC, SLCCMPT and things like that.

In my knowledge, the SLC, SLCCMPT and '''''maybe''''' SEEPROM is writable. There's also the MLC but it is not part of the SoC. It is part of the NAND.

== Why would I need this key? ==
Why? Because, for some tools that don't already have a self extracting tool to get your Common Key when redownloading for exemple, System Files (I'm watching you JNUSTool), it can be useful to have it!

Here's non-exhaustive list of all the software that uses the Common Key:

* [https://github.com/stuff-by-3-random-dudes/UWUVCI-AIO-WPF UWUVCI] - Useful for making Wii Virtual Consoles Injects
* [https://github.com/Maschell/JNUSTool/releases JNUSTool] - Useful for redownloading system files

(yes I only got 2 in mind)

== But, I don't know how to extract/get it! ==
