So I did initially use the CBHC exploit to softmod my Wii U, but I uninstalled it in favor of tiramisu when that released. Believe it or not, my Wii U bricked during a system update!
Unfortunately I'm away from home for a couple days so I can't test out game updates right away
The error did print on two separate lines, yes. My apologies for the incorrect formatting
I used your copy of rednand.ini and the same error messages came up
I can confirm that I do have an NTFS partition on my SD Card
When I attempt the Patch (sd) and Boot redNAND step, I get this ERROR in rednand.ini Line 0 No mlc partition found message. I have double checked the instructions and I have seemingly followed every step correctly, but I can post screenshots and/or files of my SD card if need be.
