Corrupted WiiU Nand or not

[fadafwet]

thanks for checking this out for me
It is a 32 GB model that I bought on launch day of the wiiu
So from what I understand it might be a hardware issue not just some file corruption
Do you haves guides on what the steps I should do next because I have no idea how to do the hard mod ou are talking about and really not comfortable on doing soldering

You would need to open up your Wii U (take care to not rip the Disc Drive cable) and solder thin wires to these vias: https://wiiubrew.org/wiki/File:EMMC_pinout_WiiU.jpg. You also need to cut the CLK trace between the two pads and solder a wire to each of the pads.
That's the hardest part. Then you either need a compatible card reader and a Micro SD to SD adapter to sacrifice. You would open the card adapter and solder the other end of the wires to it (using the CLK on the eMMC side). Then we can use that to dump the eMMC to the PC. The PC will see it as an sdcard. I like to use a raspberry pi instead of a card reader as it gives more control than a USB card reader.
Then you would remove the card adapter / raspberry pi and instead solder another micro SD to SD adapter to the Wires, but this time to the pins on the outside of the adapter and using the clk signal comming from the SoC. This will then act as an micro sd slot, where you can then put a 32gb micro sd with the written back and fixed image of the eMMC.

But the vias are quite small. You need to be careful to not damage them by heating to long. Use enough flux and don't heat them for to long. After soldering I would recommend to use hot glue or something like that for stress relief, so that you don't accidentally rip them out. I also used magnet wire, because it bends easily and therefore doesn't put much stress on the solder joins.
Maybe practice on something else first.

Also did you see what I added to my last post?

MEDIA ERROR, 32GB, launch day, hynix. Yeah you have won the bad eMMC bingo.

I do not have a rasberry pie
I think this stuff is out of my league
I will need to do much reading and watch many tutorial and test before give that a try
I think its too risky for a newbie like me

It is a shame that it broke like this, and I really take care of my consoles
thank you for your help

I mean it's already broken and micro soldering is a useful skill to have. And you never know if you can't do it before you try.
Using an old PCB you no longer need to practice a few times before is still recommended. The hardest thing is, soldering these 6 wires. Everything after that is pretty easy. We can guide you through it.
Tin the end of the magnet wire (takes a moment to burn of the isolation), put flux on the via, tin the via and then hold the wire to via and just heat it up for 1-2 seconds. There is no magic, only flux.

I just gona give you some advice,give it to someone who has soldering skills,atm its fixable,but if you never soldered,don't try it.
You just gona kill the system to unrepairable,its not a bit soldering,for this you need skills,simpy as that.
If you wanna try soldering,buy a broken pcb from some electronic device,but not try to repair a console that is fixable.
Maybe TheCod3r,he's on youtube,or voultar or some decent repair shop,but on y6our comments you writed here,you have not the skills.
Just ask what the costs are,you have to decide cause it will cost some money,much work and difficult.
