Wiiu solid blue but no video

MarcoC · Tuesday at 11:36 AM

Hello!

I have a Wii U that is not displaying anything on the screen.
I tried to install ISFShax, but I couldn't because the boot1 version was 8354.
So I upgraded boot1 img using a dump from another Wii U (just 64KB), but after that the console stopped booting and only showed a solid red LED.

I then soldered a Pico and installed de_Fuse, which allows me to boot into minute. I tried reinstalling the MLC and SLC using wafel_setup, but the console still won't boot.

What can I do next?

I tried restoring the 132K BOOT1_SLC.RAW, and with that I am able to enter Minute and boot without the Pico deFuse.

However, I still can't start the MLC reinstallation. It keeps showing the following error:

"ancast: IOS image might not be 5.5?"

You need to use ios_orig.img: here

Thanks @classiphil ! I successfully downloaded the ios_orig.img file and completed the setup of MCL and SLC.
Just a reminder for anyone using Defuse to initiate the MCL installation: make sure the drive is connected before starting the installation process.
