Hacking Successfully dumped WiiU EMMC nand with hardmod.

[QuarkTheAwesome]

Where do these diagrams come from? I have a shitty soldering iron and lifted two solder points from the board. Are there any alternative solder points?

If you're like me and lifted one of the important ones in a way that means you can't get a connection to the eMMC, enjoy your brick. I messed up CLK after trying to cut it (why tf is that the advice we're giving people?) and after a bit of searching I couldn't find another point between the recommended pad and the eMMC.
If you can still hook up to the motherboard side, you may be able to recover this with an existing dump, though it's a ridiculous idea I had after ruining my board...

Oh wait. You also put the nand chip with a diagram. Thanks you rule! I lifted RB2 and RE

 

[Kafluke]

So I soldered everything up according to these pics leeful posted earlier. There wasn't any instructions on these diagrams for where to solder gnd on the teensy so I just attached it to a ground point.

When I plug the teensy into my computer I don't get any detection. It doesn't ask for drivers or nothing. I even tried powering on the Wii U while it was connected. Nothing.

Spoiler: pinouts

Does your teensy work on its own with nothing connected to it? Have you installed the drivers and loaded the teensy with the correct hex program.

So I should see it detect even if nothing is soldered to the teensy? No it doesn't.

I tested it straight from the packaging with a USB cable and it didn't detect in windows. Device manager stands still when plugging and unplugging. Tried 3 different cables. Tried 2 diff computers and all USB ports.

Tested again after soldering the voltage regulator and cutting the trace. Same result.

I can't install drivers if it doesn't detect

Even tried hitting the little button on it a couple of times.

Does the LED flash on the teensy when it is plugged into the pc? Maybe you need to install the USB serial drivers first.

It's been a while since I set mine up but I'll ty and help. Try looking at these sites here and here.
First make sure your teensy is working properly by loading the LED blink programs on it with the 'Teensy Loader' program.

When you know how to load programs onto the teensy then use the NANDway_SignalBoosterEdition.hex with the WiiU. (You will need to know which port your teensy is running on.)

Did you flash the bootloader to it? It seems like I needed to do that before the teensy was detected.

How do I flash the bootloader to it if windows won't detect it? I guess I need to do more research.

awesome, I'll try this and report back. Missed your post for some reason.

So I desoldered every wire from the teensy and then tried plugging it in. No dice. I double checked the voltage regulator. Here's the one I soldered on:
https://www.digikey.com/product-det...CP1825S-1802E-DB/MCP1825S-1802E-DB-ND/1636132

Everything checks there too. No lights on the teensy, no detection in windows. I tried running the loader and it tells me to push the button but it still doesn't detect. Weird.

 

[Kafluke]

I accidentally ordered the wrong teensy at first. I didn't get the signal booster edition. Just regular 2.0. I just plugged that into my computer and it lit up perfectly. Did I do something wrong when I soldered the voltage regulator?

 

[Leeful]

I few things you could try:

Install the usb serial driver here. Or/and install the Arduino and Teensyduino software here.

Desolder the regulator and solder the pads back together(the ones on either side of the track that was cut) to see if the regulator was at fault.

Yeah I'll try that next. I have the USB virtual serial drivers and they work with the non signal booster teensy that I have.

 

[Kafluke]

Ok. Got it to detect by removing the voltage regulator and rejoining the other two pads

 

[Leeful]

Looking again at the link for the regulator you used and it says in the description that it is rated at 1.8V. Thats could be why it was not being detected.
This one here should work as it is a 3.3v regulator.

Yeah I think you're right. I'll order a new one

Hello,
I'm going to dump the NAND of my Kiosk Unit this way. But I'd like to know if this "cut track here" only refers to the removal of resistor 26 or if I should also cut the track beneath it. (Why is there even a track beneath the resistor?)

And what's the name of these connectors utilized here?

EDIT: I have ordered a bunch of Arduino/Raspberry Pi jumper cables (m2m) and a solder less circuit board.
But still, I'd like to have the first question answered..

 

[Kafluke]

Okay, I got the correct voltage regulator and the correct soldering iron tip. However, I can't get the Teensy to load the drivers in windows. When I load the serial drivers I get this message:

So when I plug in the Teensy++ 2.0 the light on it starts to blink. When I press the button this shows up in device manager.

Any ideas? I have a Teensy 2.0 (non ++) and it just detects and works find when I press the button. I've tried on two different Win10 computers. Did I get a bum Teensy?

 

[Kafluke]

Just a note. This is after the voltage regulator has been soldered to the teensy. It works fine without it.
