He was able to fix it, so why wouldn't the OP be able to?
Well, that's dumb.Because Smealum had his OTP keys, if I recall correctly. Meaning he was able to decrypt his NAND dump, revert the changes to system.xml, re-encrypt and flash the fixed NAND.
OP doesn't have a copy of the OTP keys for his console.
He doesn't have a backup of his sysNAND from the NAND chip. He only has a dump of the NAND on his SD card from redNAND.That's what I meant. If you have a backup from before you did any changes to system.xml, what changes do you want to revert? The system.xml in that backup should be alraedy okay.
I'm honestly not certain. I haven't researched whether or not the NAND dump from redNAND is clean, and the fw.img holds the patches, or if the NAND dump gets patched and the fw.img is only responsible for loading in to it.I haven't read into redNAND much. But isn't the process like dumping original NAND, then inject patches into it. So at some point there should be an unaltered backup, that can just be flashed back. About the three files, I thought the WiiU had two NAND banks, one for Wii, one WiiU. I don't know where the third comes from, but they should be flashable seperately.
I'm just curious, because I only used my teensey2++ on PS3 before...
@QuarkTheAwesome - Wait, from what I understand (could be wrong), the OP has a backup of his NAND from before he made any changes. So why would he need the keys? He could just flash that backup to NAND. From my understanding he only needed the keys if he didn't make a backup beforehand to dump, decrypt, repair and re-encrypt.

Even if he found a way to merge the 3 IMGs created by SDio into one proper IMG, whose to say the console would even play nice with a modified NAND like that.
seting default title to something not in internal storage - in the USB instead. but the wii u can only mount (access) USB when wii u menu loads, but instead the game / title from USB was gonna load.... you get the idea.But what was the reason of bricking? Did you write something wrong besides the correct number in Region_Game? What does Brain Age have a connection with the brick? I couldn't get it..
alright big papaYou may have a point.
I'm unfamiliar with the formats and such redNAND uses; so I can't say for sure exactly what's behind those files.
What I will say is that if the names of the files are to be believed; each one is a dump of a physically separate chip on the Wii U; thus you don't need to merge them since each one is for a different chip. If you're lucky you'll only need to flash the SLC file to fix system.xml.
There are a few prerequisites:
These conditions met and with confirmation by someone familiar with redNAND you may be able to use a Teensy to flash your SLC.
- The .img is correctly encrypted with your console-specific key OR you have an OTP dump
- The image is a complete dump of the whole chip and is not corrupt.
- The image is clean; with no fake titles or patches.
I also meant to tag @Sans-Serif in the last post; somehow messed that up :3
