In case you, or anyone else that have problems, want to try again:
I use the same SD card and the first dump works well. The difference is before dumping NAND, instead of 22 GB (about 22,528 MB) I only created 20,020 MB FAT32 primary partition with default cluster size (like 16kb) by using the following command with in the MS command window (running with the administrator right):

Code:
diskpart
list volume
select volume x <-- replace x with the right number for your SD card shown in that volume list
delete volume <-- make sure you are deleting the right one
list disk <-- just for checking
create partition primary size=20020 <-- in MB
list volume
format fs=fat32 quick <-- default cluster size
list volume <-- just for checking again
exit

The reason I put about 19 GB instead of 22 GB because I saw the following part in the 0x10700000.s file from the code repository of iosuhax in github:

Code:
USB_BASE_SECTORS equ (0x2720000)
SLC_BASE_SECTORS equ (0x2F20000)
SLCCMPT_BASE_SECTORS equ (0x3020000)
MLC_BASE_SECTORS equ (0x3200000)
SYSLOG_BASE_SECTORS equ (0x6D00000)
DUMPDATA_BASE_SECTORS equ (SYSLOG_BASE_SECTORS + (0x40000 / 0x200))

The smallest base sector shown as 0x27200000 (the code may need to read starting at that sector in the SD card) = 0x27200000 (sector) / 0x2 (sector per KB) / 0x400 (KB per MB) / 0x400 (MB per GB) about 0x13 GB or about 19.56 GB (20,032 MB). And with a typically 1 MB offset in the creation of partition, to be on the safe side, I just put the size as 20,020 MB or about 19.5 GB. Hope this helps, and let me know whether this works or not for you.

Cheers.
Do you know which size would a 8GB Wii U require?

Wow that's gonna suck. The whole reason I love the Brazilian method is because I can play my games without going through the browser each time like with Loadiine
Was you in the 3DS scene before menuhax? We had to run the exploit throught Browserhax/MSET each time lmao. Throught this method, you can install ilegitimate DLCs and homebrews on your home menu.
+ I think coldboothax is being worked on

No, fortunately I came in after menuhax. By "install ilegitimate DLCs and homebrews on your home menu." you mean to RedNANDs home menu, correct? Cold boot sound great lol

Well, Smea's video shows his Wii U coldbooting into redNAND. Yup, I meant redNAND's home menu.

So, since I own a 8GB Wii U, is it possible for me to use a smaller SD Card, or is it hardcoded in the dumper?
It's hardcoded, so you'd need at least a 64GB card.
Tbh, I'd recommend waiting. Someone's currently working on better dumper. It will probably have better support for 8GB models than the current dumper.

Do I need to Format my SysNAND before using RedNAND?
No, nor would I really recommend to do that right now. There's currently no way to restore NAND backups to your sysNAND.
Also, if you format your sysNAND, you're going to have to format your USBs as well (if you're using any).

Thanks! I think I heard about SALT or WiiUBrew's dumper being 100% reliable so I guess I'll wait.

Dang, seriously? Guess one wouldn't be able to use RedNAND and USB-installed games?

You can, but when you format sysNAND, it won't allow you to use your currently Wii U formatted USBs (on both sysNAND and redNAND) after the format. You'd had to reformat the USB after formatting sysNAND.
This means you'll lose your games and saves that are on that USB (unless you backed them up beforehand).
