This guide was created when the browser exploit was unreliable on anything higher than v5.5.1. Since that's no longer the case, this guide is probably useless for >99% of people.

This guide is for people who want to use the internet browser as their primary entrypoint because they don't want to pay for Haxchi. If you plan on buying a DS game and installing Haxchi or CBHC, then there is no reason to follow this guide. Haxchi users can go ahead and update normally to v5.5.3/v5.5.4.

Note from Cyan : Since PokeAcer is banned and deleted his website's guide, here is a new one from Lacius.

Guide from Lacius

Update: There is a browser exploit for the v5.5.2/v5.5.3/v5.5.4 browser, but it is unreliable. If you already installed the v5.5.2/v5.5.3/v5.5.4 browser and you plan on using homebrew on a regular basis, you can use the exploit to install Haxchi. If you're on v5.5.1 or lower (particularly if you don't have Haxchi), it is recommended that you not update your browser to the v5.5.2/v5.5.3/v5.5.4 version, since the v5.5.1 browser exploit is very reliable.

• This guide is for Wii U systems on system versions too low to use CFW. This guide is also for people who want to update to v5.5.3/v5.5.4 while keeping the v5.5.1 browser for its reliable exploit.
  • If you have Haxchi or plan on installing Haxchi, it is safe to connect to the internet and install v5.5.3/v5.5.4 instead of following this guide. You should immediately block updates after you're done.
  • If you plan on using the internet browser as your primary exploit because you don't want to spend money to install Haxchi, this guide is for you.
• Your Wii U needs to be on v5.3.2, v5.4.0, v5.5.0, v5.5.1, v5.5.2, or v5.5.3 for this guide to work.
  • If your Wii U is on v5.3.1 or lower, you will need to update to v5.3.2, v5.4.0, v5.5.0, v5.5.1, v5.5.2, or v5.5.3 using a game disc before you can use this guide.
  • If your Wii U is on v5.5.2/v5.5.3/v5.5.4 already and you have the v5.5.2 browser installed, then there's no reason to follow this guide. You can connect to the internet and update to v5.5.3/v5.5.4 normally.
• If you use my title lists, this guide will update your console to v5.5.3/v5.5.4, but it will update/keep the browser version at v5.5.1 in order to retain the reliable v5.5.1 browser exploit.
• Do not disable your DNS filtering after updating, or the browser will update itself to the latest v5.5.2 version!
  • In addition to the using the proper DNS filters, you can also follow this guide to delete the update folder on your NAND to block updates. Using both methods (DNS filters and deleting the update folder) to block updates is recommended.
  • Never remove your DNS filters. If you need to use the eShop or update games, just use NNU-Patcher.
  • If you don't block updates and Nintendo releases a new system version, your Wii U will automatically download and install the update, potentially removing your entrypoint and/or CFW. Block updates!

Required Files
Everything except Java and the common.key file can be downloaded at the bottom of the thread.

• OSTitleDownloader
• wupinstaller_y_mod_without_blacklist
• Java
• common.key (find it yourself)

• USA title lists (only for USA consoles)
• EUR title lists (only for European consoles)
• JAP title lists (only for Japanese consoles)

Instructions

Install OSv10 (000500101000400A) last, as it will freeze your Wii U (this is normal).

1. Extract OSTitleDownloader.
2. Download and extract the title list for your Wii U's version and region. Alternatively, you can make your own title list.
3. Put your title list into the folder with titledownloader.jar and rename the title list as LIST.txt
4. Find common.key online and put it into the folder with titledownloader.jar and your title list.
5. Open a terminal/command prompt in that folder and type: java -jar titledownloader.jar -l LIST.txt
6. Once it’s done, copy the install folder to your SD card.
7. Extract and copy wupinstaller_y_mod_without_blacklist into your Wii U apps folder on your SD card.
8. Run WUPInstaller Y-Mod from the Homebrew Launcher using the entrypoint of your choice.
9. Select all titles except OSv10 (000500101000400A) and hit install to NAND.
10. Once all titles are installed, install OSv10 (it will freeze, and this is normal).
11. Reboot.

Your Wii U should now be on v5.5.3 or v5.5.4 if you used one of my title lists, but the browser will still be on the reliable v5.5.1 version that can launch the Homebrew Launcher consistently.

Offline and official updates

You can also update offline using a game disc. It doesn't involve homebrew at all.

Games containing the v5.5.1 update:

• Cars 3: Driven to Win
• Darksiders: Warmastered Edition
• Just Dance 2017
• Minecraft: Story Mode - The Complete Adventure
• Paper Mario Color Splash
• Shantae: Half-Genie Hero
• Skylanders: Imaginators
• The Legend of Zelda: Breath of the Wild

Spoiler: older guide from PokeAcer

I have migrated the guide to GitHub, with version data lists etcetera.
It is now accessible at https://pokeacer.github.io/WiiU551/

There is also a potentially new and improved method, at https://pokeacer.github.io/WiiU551/NewMethod

The old version is below, incase anybody wants it.

Spoiler

Have you left your Wii U off, and now cannot upgrade to 5.5.1 because 5.5.2 is out? If so, this is for you!

WARNING: You could potentially brick if your Wii U powers off before all update titles are completely installed; I am not responsible if this occurs!
Do not use a NUS Title List that is not from your region!
Please note this copy of WUPInstaller has no security checks; if you install the wrong title version, again, I am not responsible!​

You will need:

• The 5.5.1 update files
• My unsafe version of WUPinstaller, downloadable here
• A lot of patience
• A PC

Obtaining the 5.5.1 Update files:
Remember, these cannot be legally obtained without going to NUS or dumping from your own discs; they are copyrighted content.

Disc Method:

Spoiler

If you already have a Wii U with 5.5.1, or a friend with one, you can use WUDump and extract the update partition using VGMToolbox. Follow the VGMToolbox instructions on how to open a WUD, and then extract the partition starting with "UP" - please note that you will be installing titles you may not need to reinstall, so I suggest NUS method.

NUS Method:

Spoiler

Go to the ninupdates page for your region: PAL, NTSC-U, NTSC-J, and look for titles that have updated since your version. For example, if you are on 5.4.0E and you have seen that ErrEula is updated between 5.4.0 and 5.5.0, install the 5.5.0 version. However, Internet Browser was updated in 5.5.0, and 5.5.1, so you want to install the version 5.5.1 has - if you install a version to just update it again, you will waste your time. This method is now a lot simpler!
Go to the NUS List (Scroll down a bit) and find your version number and region (It has to be your region!). There will be a list of title IDs and the versions to download. Use a tool that can download encrypted from NUS - JNUSTool and NUSGrabber both work.
If you use NUSGrabber, the command syntax is: "nusgrabber.exe TITLEID versionumber".
If you use JNUSTool, the command syntax is "java -jar JNUSTool.jar TITLEID vVERSIONNUMBER -dlEncrypted"

Steps:

NOTE: It is advised that you install the OS title last (OSv10 000500101000400A), as it may freeze your Wii U​

1. Make sd:/install/ and put in the contents of one of your title update's folders, and install to NAND.
2. Delete contents, delete title you've upgraded from your PC, use next folder, repeat.

Yes, this is tedious, however I am not personally able to do anything about this. If a Wii U dev wants to help out, they simply need to alter dimok789's WUPInstaller to add a feature that scans a folder, and installs all titles in the folder. You will also need to change L297 of src/main.c - where it says "0", change to "1". If someone does this, please inform me!

Credits

• @Kafluke for inspiring me to try this (This sounds snarky but I'm being serious, he genuinely made me want to try)
• @trololo for testing this, and providing the 5.4.0U -> 5.5.1U update list
• @Ryccardo for JPN lists and EUR lists

Help Me Out!
I clearly don't want donations, but I do need help. I need:

• USA update lists for <5.3.2, 5.3.2
• JAP update lists for <5.3.2, 5.3.2, 5.4.0, and 5.5.0

 

[Ryccardo]

-Y Mod doesn't iirc as the dev never did want to implement it; that's not an issue except last I remember after every title it seemed to relaunch into the Wii U menu - if someone wants to try and use -Y Mod and it works, please let me know!

In my experience it depends on the entrypoint, it reloads before and after every title on browserhax but not if using the HBL channel!

Basically it's just permission stuff (Mii Maker doesn't seem to have enough permissions to install a title, so you just launch menu that has enough permissions, https://github.com/dimok789/wupinstaller/blob/master/src/main.c#L326-L327, in the hbl channel case, you already have enough permissions, so no need to launch the sysmenu)

Thanks for this, I have been having a hard time with my 5.3.2U wiiu updating it. I downloaded a bunch of system titles that were different but I couldn't find a WUPInstaller that would let me install anything. I think I'll wait though until a list is made but I think I may have downloaded all the correct stuff.

The lists are on my website; if you go there, you can save them and use the New method to do it.

Right on, this one right? https://pokeacer.github.io/WiiU551/NewMethod I'm just waiting for the 5.3.2 USA list and I'll be good.


If I were to attempt to make a list would you be able to proof it. I checked the titles I downloaded and they seem to line up.

--------------------- MERGED ---------------------------

Actually my list is almost identical to this one https://pokeacer.github.io/WiiU551/lists/VersionData/540U.txt but for '0005001010041100' I have v496 instead of 560. Also I have an extra title which is 0005001010040100 and version 213

^^nvm I get it, that's the version data title I dont think I could downgrade it otherwise it would be easy to just update with a disk.

No no, as in use the old method's copy of regular WUPInstaller_Unsafe

 

[TheOneDemon]

So I used the old method last night from 5.3.2E with ONLY VersionData but it updated to 5.5.2E in system settings and is auto detected on Loadiine.ovh and 5.5.2 and always get the error when trying to do it, tried on 1.3 and 1.4 launcher and on 5.5.1 and 5.5.0 on the site.... Also tried the link you gave but same thing. So I just bought another Wii U with 5.5.1 already on it and just going to use that.... So yeah not safe even with just doing VersionData.

Before you blame the safety:
If you typed the version wrong (did you see how NUSGrabber and JNUSTool take the version parameters DIFFERENTLY?), it will have downloaded 5.5.2 stuff.
There is a reason we're going to the New Method.

Before you blame the safety:

I only used JUNSTool and WUPInstaller_Unsafe... It doesn't say anything about NUSGrabber, you only say to replace the "LINE" from the JNUSTool command to the ones from VersionData file individually and then use WUPInstaller. So no idea what you're talking about.

Why, when there's tools like Maschell's titledownloader that will work correctly?
If @C0mm4nd_ fixes his bug in his fork of Y-Mod, the new method will replace the old one.

If you upload the files there will be less user errors and the guide will be easier. Do what you want .
