I have all of that done. Do I plug back in the Wii U at this point and start up?

Now that your SD Card is properly setup we can go ahead and start the rebuilding of the MLC. Like I previously said this is going to wipe the internal memory of the Wii U and will start fresh. So if you don't have your backup for your save data you should make that before proceeding.

Put the SD Card back into the Wii U

Turn the console on and blind steps are this:
1. Press power button 2 times
2. Press eject button 1 time
3. You should hear the disc drive spin
4. look at power LED, if its blinking blue or orange this means its working
5. Walk away for 20 minutes
6. Check on power LED if it is solid blue or orange, that means its complete. If its still blinking wait longer
7. pull AC adapter out of console to power it off.
8. post log on your SD Card Wafel_setup_mlc.log for review
9. Remove wafel_setup_mlc.ipx from your SD Card.
10. Put SD card back in the Wii U and power on the console
11. Press power button 2 times, followed by eject button 1 time If everything works you should get the initial setup screen for the Wii U console.

LED is just remaining purple, no disc drive sounds aside from initial boot...

@RollingBox

My apologies I didn't proofread what I wrote and for some reason the first step is actually the second step. No worries no harm was done. Let me correct this and you can try again. What was missing was the push power button 2 times step in order to move to the proper item in the menu. It should work now. Try it again 

Yes! We have blinking blue and disc drive sounds!

As for the restarting after removing wafel install the "press button 2 times, followed by eject button 1" did not provide any changes in LED (still purple), and no visuals. There was however some brief disc drive noises

Well given the state of your eMMC I am not entirely surprised. Doesn't look like you will be able to do this with a screen output. You need a NAND-AID. That being said once the NAND-AID is installed the process to rebuild the MLC is nearly identical, there are only a couple additional steps. So doing it blind won't be all that bad. 

Just out of curiousity, if you power cycle the console and you follow the last step again: Push power button 2 times, followed by eject button 1 time does it do anything different?

Also what firmware version is on the console?

I unplugged and tried three times to the same result, my firmware is 5.5.3 U

I've been looking at several of the circuit board images and trying to take very careful note of what's getting cut and what number will connect to where

Might as well download the SLC files using the MLCRestorerDownloader and put those on your SD Card in the same directory as the 52 titles.

My full guide for the NAND-AID is here and there is a video that shows everything being done. The only part you are cutting is trace R26. Which version of the NAND-AID will you be installing? 

(Just checked supplies and I didn't get flux so I guess soldering is tomorrow night    )

I have done that before, where I went to repair a console and I was out of flux and forgot to get some. Not going to be doing any soldering work without it, that is for sure.

And I did try it again with the SLC folders in with the MLC ones to no avail. Thanks for all the help this weekend, my flux should be here before I get off work tomorrow.

You are welcome. No harm in trying again. I knew it was a long shot and my gut told me it was unlikely to work. The logs you provided show a very badly degraded eMMC. When you rebuild the MLC its writing data to the eMMC, that data is the firmware/OS the Wii U console uses. If the data cannot be written due to a bad eMMC than rebuilding will not work.

That's what I get in the long term for buying a console day one.

But I also had a thought, that maybe I downloaded the MLC parts wrong? I dropped the otp.bin file in the root of the MLCrestorer folder and I'm not sure if that was correct way to go about it?


But also, probably just that bad off and needs that NAND-AID. (Thanks Nintendo)

Unless something has changed without the otp.bin file the downloader should not download the 52 titles and it would throw an error. Also its not just owners who purchased the console on day one. I have repaired I believe 41 of these consoles to date and several of them (I don't remember the exact number, but I am pretty sure it was 5 or so) were sold in late 2015 and had bad/failing eMMC.
