The way I used to do it was tedious and was quite complex, however with the v2.0 release of the wafel_setup_mlc plugin, region changing has become much simpler.

It is identical to just rebuilding the MLC, but this has region changing specific notes added.

This does not change the region of the Gamepad, however you can still use an out-of-region gamepad with Aroma, which can be loaded with a Stroopwafel plugin, so you don't need to worry about getting a gamepad from the region you are changing to.

Following this guide will wipe the MLC. You should back up any saves you care about before following. Its possible to do it without wiping the MLC, you just skip the Erase MLC and Delete scfm.img steps, but you will have to remove the old titles with this wupclient (Right Click -> Save As).

Keep an OTP and SEEPROM backup. Nothing should go wrong, but it is better to have the most important backups and not need them vs. need them and not have them.

I AM NOT RESPONSIBLE IF YOU FAIL TO FOLLOW INSTRUCTIONS PROPERLY.

What you need

• Install isfshax. This is a requirement. You cannot region change without it. (You can also use de_Fuse, but at that point you probably already know what you are doing.)
  
  • Stop at the "Booting" section.
• The release of the MLCRestorerDownloader for your OS.
• The latest release of the MLC setup plugin.
• The latest release of the Payloader plugin.
• The latest files for Aroma. (If you already have it, you do not need to recopy it)
  
  • Read and tick the 4 boxes -> Click on Download Payloads and Download Base Aroma

Downloading the MLC Titles

1. Extract the MLCRestorerDownloader you downloaded.
2. Copy the otp.bin into the extracted folder.
3. Open a command prompt / terminal and run the application (ie .\MLCRestorerDownloader.exe for Windows users).
4. Type in 1 the for MLC titles.
5. Type in the number for the region you want to change to (ie 2 for USA).
6. Wait for it to finish downloading. You can do part of the next section while you wait.

SD Setup

1. Copy the wafel_setup_mlc.ipx to sd:/wiiu/ios_plugins.
2. Copy the wafel_payloader.ipx to sd:/wiiu/ios_plugins.
3. Copy the two wiiu folders from the Aroma .zip files to the root of the SD.
4. Copy the root.rpx from sd:/wiiu/environments/aroma to sd:/wiiu.
5. Make a folder called wafel_install on the root of the SD and copy all 52 MLC titles here.

Region Changing

1. Boot the console.
   
   • If it does not automatically go into minute_minute, go install isfshax.
2. Navigate to Backup and Restore.
3. Select Erase MLC and then press EJECT to confirm.
   • If it tells you MLC Erase not allowed, go install isfshax.
4. Select Delete scfm.img and press EJECT to confirm.
   • If it gives you a warning about bricking the console, do not continue and install isfshax. It's not playing around.
5. Go back to the main menu and select Patch (sd) and boot IOS (slc).
6. Wait for the LED to start blinking blue, this means the setup has started. Wait for it to stop blinking, that is when the setup has finished.
7. Shut off the console and put the SD back into your PC.
8. Check the wafel_setup_mlc.log file on the root and make sure there were no errors (everything should have 00000000, except for SetInitialLaunch, which will have a 1).
9. If everything looks right, delete the wafel_setup_mlc.ipx file from sd:/wiiu/ios_plugins.
10. Boot the console again, select Patch (sd) and boot IOS (slc), and you should be greeted with initial setup. Success!

Manually fixing the sys_prod

You only need to do this section if the MCP_SetSysProdSettings returned error FFFBFFEE, if it returned a 0, then you can skip this section.

1. Install Python on your PC.
2. Download this wupclient.py. (Right Click -> Save as..)
3. Edit the IP Address on line 140 with the Wii Us IP. Do not change the port.
   • You can get the IP by looking at your router settings.
4. Make sure the console is booting into Aroma and is on the AutobootMenu.
   • Hold + on the Gamepad while booting to get to the AutobootMenu.
   • Aroma should automatically load with the wafel_payloader plugin.
5. Open a terminal where the wupclient.py is.
6. Run python -i wupclient.py.
7. When it successfully connects (should have a 0x0), run w.dl("/vol/system/config/sys_prod.xml").
8. Open the sys_prod.xml in a text editor, and change product_area and game_region to the new region.
   • JPN - 1. USA - 2. EUR - 4.
9. Save the file, and then run w.up("sys_prod.xml", "/vol/system/config/sys_prod.xml").
10. Run exit() on the wupclient window, and then reboot the Wii U.
11. If you did everything right, loading the Mii Maker in the User creation should not crash.

After Region Changing

You can keep isfshax installed, or you can uninstall it. I would keep it, so you can load Aroma on boot without needing to install PayloadLoader, or as some form of 'brick protection'.

You can region change the Gamepad with DRXutil, but no instructions will be given here. Use at your own risk!

Damn this console knows how to disappoint

No helping signs, no nothing, just error code 150-3032
The all-knowing internet gave me a clue of - memory. I do have a usb drive in a Wii U rn, should I unplug it?

 

[Lazr1026]

150 indicates theres something wrong with the FS. removing the USB drive may help, but it probably wont.

If it doesnt change anything, go to Backup and Restore -> dump crashlogs from slc, compress the dumped logs, and then post them here.

 

[TheChel98]

Yeah, the problem was the USB, I'm now officially on the first setup screen.
Thanks for all the help, appreciate it!
I think that's kinda it, yeah?

 

[Lazr1026]

yeah thats it

Aloha, Followed steps, In Region change section, got to :
10. Boot the console again, select Patch (sd) and boot IOS (slc), and you should be greeted with initial setup. Success!
However, instead, I get a MINUTE Main Menu, and select Patch (sd) and boot IOS (slc) and some text, and a Wii U screen, then black text over the white WII U menu splash screen, and then the white text again (some kind of boot loop). ( Don't see option of how to upload a picture or video on this thread). Anyone have any ideas on a possible step I missed or how to go backwards to reset the WIi U (I have the backup of the SLC.raw and SEEPROM and OTP). Thanks.

 

[Lazr1026]

put the PayloadLoaderPayload back into the sd:/wiiu folder.

 

[unqone]

Thank you!

Hey, also a quick question. After the installation of EUR region it seems as the TV button on the controller doesn't really work, just does a screenshot and swap between screens. Any reason why he does that?
