Hacking Wiiu Nand Dump

[crediar]

You also have to dump the 2nd NAND if you want to switch between versions since it is a dual 512MB NAND, one "side" for Wii U the other for vWii.
Dumping this NAND is a lot harder though.

Does it matter if I don't restore the vWii NAND? Would it brick the Wii U part?

 

[hashcheck1]

Is Vwii nand dump via Vwii nanddumper app? Also to confirm you have to backup both wiiu nand + Vwii nand together and flash both that are on same fw. Ie Vwii 5.4 and wiiu 5.4fw. And then Vwii 5.5 & wiiu 5.5fw

if someone can do a nandmod service in the U.S. for the wii u let me know

It can be dumped and restored using vwii softmods though.

Although of course, that won't protect people against vwii bricks. But theoretically it could still be restored from Wii U mode.

 

[crediar]

You can only dump the vWii side in vWii mode.

 

[hashcheck1]

If on 5.4fw and do vwii nand back up via soft mods and nand wiiu backup and then you update to 5.5fw.
If then downgrade wiiu nand to 5.4 backup and Vwii nand is on current 5.5 will you be able to boot into Vwii mode to downgrade that nand or will that cause issues. Assuming there's changes to isos in Vwii

Ok but how do you backup vWii? Where is the guide?


Also what about the contents of external USB drive? Are those affected during restore? Do I have to backup games updates or saves from external drive?

Moving all saves updates and games to external drive is a good move before backing up the NAND?

Wow... couldn't you atleast read the first page?...

In process of doing mine and install microsd and cardreader... will update with pictures soon

I'm asking for the vWii guide not Wii U nand.

 

[EmceeKerser]

Looks easy, are the SD readers as temperamental with this mod as they are for 3ds?

Heads up if good with soldering you can read and flash Vwii nand with a infectus chip.

An infectus will read and write just about any nand chip from my understanding, if you take the time to hook it up. People were dumping PS3 NAND's with it way before they were of any use to others. I think they did the same thing we're (or at least I am) trying here, to use what version you want. They ran into a problem with the syscon on PS3 though IIRC, which also knows what version the system should be on. It's been a while, though. But any how, those pinouts are for the original Wii, I'm not sure if the chips are the same or not. Crediar or someone would know more.

Infectus, you started in my life as a modchip for ps2, keep chugging! :beer:

 

[Adr990]

Well, I tried to do it like they did and I double checked with a multimeter, the connections are good.
But the card doesn't get detected.

On WiiUBrew they are using all Data points and bridge a 50k resitor between Data3 and VCC to get the card to detect.

Has anyone tried anything so far anyways?

 

[hashcheck1]

Like the new 3ds and o3ds emmc can be very picky with card readers. I use a Realtek chipset card reader and find its the most reliable. Checkout n3ds nand dump threaf

 

[FaTaL_ErRoR]

So, have any of you successfully flashed older nand firmware back to wii u yet? (from 5.5 to lower)

 

[VashTS]

I'm curious as well, who is going to be the guinea pig

 

[hashcheck1]

Hopefully 5.5fw exploit found one day. Have a 5.5fw nand backup but didn't know about nandmod until stupid wiiu updated. Will test downgrade once a new firmware is out.. if works like 3ds those with soldering experience will be able to easily keep exploit nand and latest nand and flash between

Could you link me which one you've bought?

--- Edit: ---
Ok, I've purchased this one:
Anker USB 3.0 Card Reader 8 in 1

Once I get it in the mail I can test it again.
Did you use the WiiUBrew method, or the one from Reboot.ms?

--- Edit 2: ---
Time for some pictures, while waiting for the new card reader...
I removed my old set up, which was a bit different, along with a lot of hot glue. But it was no biggy, gotta love hot glue.

Now I've set up the following new 'dual' set up: (WiiUBrew and reboot.ms method... no hot glue)

Spoiler

The hole in the shield was made so I could test the points with my Multimeter for the set up I had on the other side.. the one with a lot of hot glue.

The purple, white and brown wire are there to make the mod complete according to WiiUbrew.
Therefore there also is a 50k resistor connected between vcc and Data3 on the SD Card.

--- Edit 3: ---
Closing it up:

Spoiler

The wire is bit long, so to make the sliding cover I have to modify the case some more or think of something else to make it 'stealth'. (Like I actually had before)

--- Edit 4: ---
Where can I get a Infectus NAND dumper in the EU?
I would like to make/restore a Wii NAND dump too, to make downgrading possible?

@hashcheck1
I saw over here: https://gbatemp.net/threads/n3ds-nand-backup-possible-i-hope.381506/page-38#post-5589987
That you also used a similar card reader like I have in my pictures. I know there are a few variants of this one, I just wonder If you also have the Intergral version of it?

And, ofcourse, does it work for you on the Wii U eMMC?
