I came across a Wii U console at goodwill. The console was sold as not powering on, but in my experience many of the consoles I have purchased from a goodwill store are rarely tested properly and often not at all. For $10.00 its worth the buy because either the console is fully functioning or I get to make a video repairing it. For this particular console, it turned into a video and became the perfect console to showcase how to use defuse to repair a Wii U console.

This is only the 2nd console I have come across that required Defuse to diagnose and repair. I often get comments asking about how to use defuse, and the reason I haven't been able to make a video is because in my experience the consoles that require defuse to repair are rare. Luckily today we have just the console to showcase how to do that. The video of the full repair can be viewed below.

A couple things before we get into the video repair. This console was sold as not powering on. However upon getting it on my test bench it was found to power on without any problem. The console would freeze at the Wii U logo screen. Additionally during testing I realized the fan was bad and I replaced it. When attempting to use a UDPIH to get into the recovery menu & load ISFShax the console had no video output and exhibit a strange blinking LED behavior that wouldn't let me install ISFShax. Without ISFShax defuse is required to repair the console.

I have attached the log files for this Wii U console.

Correction: I state in the video that you have to use the power and eject button on the Wii U console to select yes or no in the minute menu. This is inaccurate. You can use the letter P for yes/continue and Q for no/quit on the keyboard to navigate the menu while using defuse. 

There is an error in this video about how to read the meta.bin using a hex editor in order to identify which log file is the newest. The hex editor gave us 000001D6 which converted to decimal is 470. We have to take the 470 and use a modulo 100 and find remainder which tells us the newest log file. You can use the modulo calculator  at this link to make it easy.
so 470 goes into the dividend box and 100 into the modulus box. that gives us 70. So log 70 is the newest log file. Coincidentally I actually did view it in the video, but I wanted to clarify how to get the correct log file. My mind doesn't remember everything and clearly as you can see in the video I was like huh what the heck is this. Also to clarify there is nothing wrong with the meta.bin file. My assumption that is was corrupt is incorrect.
