I accidentally turned my Wii U off during a system update

LAGO · Apr 4, 2022

I need help. I hooked my Wii U up for the first time in forever and it started doing a system update. Which I thought was weird, and took the absolute worst course of action and turned it off. Not my finest moment. You know when they tell you not to turn off during a system update? They mean it.

Anyway, I can turn the Wii U on and it gets to the Quick Start menu. Anything I click gives me the You turned the power off screen and once I click OK it gets to Please Wait screen and freezes after 2 - 20 seconds.

A few years ago I did the Brain Games Haxchi mod but honestly I have forgot everything about it. Didn't actually do anything with it either, which is a shame.

Anything I can do? And thanks for your help. I truly appreciate it.

If you have a backup of your NAND maybe you can restore it.

Did some google on this. Is there a way to do that without doing a hard mod?

Assuming I have the backup. Not sure if I do honestly.

Nope hard mod is the only way if you got a brick with a NAND backup to restore with

The worst part is, the latest Wii U update doesn't even break any cfw or homebrew. You'd have been perfectly fine to update and not even have any headaches to deal with from broken mods or anything like that when it would have completed.

My console starts fine and runs homebrew no problem. Is there a way to restore a NAND backup without hardmod? It's only fault is that it crashes when I try to open the settings app

You could also reinstall system settings. Which I would recommend before you try a nand restore.

1. Download system settings from wupdownloader. Just type in the titleid for your region.
2. Place its files into SD:/install/
3. Launch udpih recovery-menu
4. Press install wup

After that systemsettings should no longer crash

Many thanks, I'll try once the Raspberry pico arrives, hopefully tomorrow.

I could try using my switch, but seeing as I soldered a microcontroller to the mother board to act as an internal payload dongle, I don't wanna risk any blown fuses or such.

I'll keep you posted if this works or bricks the console, I already bought and modded another WiiU, just in case.
