so. my smart brain recently decided to get myself a wii u, for hacking, and, y'know, to play games on.
because i decided to be extra smart, i decided to get a bricked (cbhc brick) wii u with nand backups, and then do the hardmod to fix the brick myself; which yes, is and was a fun journey, and i learned a lot both about soldering and nand chips, but it's kind of hard to quantify this into some objective measure of whether this was worth it or not.
on my initial attempts to install the hardmod, i ended up damaging some of the traces, which pushed me towards getting some actually usable soldering equipment and a few more materials in order to fix the traces while also still having to do the hardmod.
fast forward to me actually successfully repairing those traces and hooking up a teensy to the nand chip (both with quite a bit of trail and error), i managed to actually rewrite the nand backup to the nand chip.
in theory, this should have been the end of it, however, now the console won't output any video (and presumably also no audio, but i haven't set audio up at this point).
i know that the console was still perfectly capable of booting up to the error code that corresponds to the cbhc brick before i rewrote the nand, indicating that fixed traces were indeed working, and that i didn't accidentally damage something important somewhere without noticing at least up to that point.
even though there's no video(/audio?) now, the light on the front still turns blue when turning on, the fan spins, and the disk drive makes some disk drive noises, which i guess is all the clues i have to diagnose what might be the problem. i assume these mean i'm getting at least past boot0 and boot1, but then the console gets stuck somewhere (and without video and an error code to look up, it's kind of really hard to narrow it down further). the one final clue i have it that apparently, the wireless gamepad communication doesn't seem to get initialized, which kind of rules out that the video mode is just set up in a bad way (i only really have hdmi to work with :/).
i have also confirmed that yes, the nand image i wrote is indeed correctly on there now; with the exception of a few blocks that seems to more or less randomly change? i'm currently thinking that this is the os writing/rearranging some minor things on booting or something (at least it would fit with what i'm observing...)
currently, i'm just stumped with what could possibly be causing this; my current approach is to try to get the nand chip powered up without powering up the wii u to maybe rewrite the backup or something, but that's neither working yet nor do i have any good reasons to believe that will fix it.
i'm not necessarily asking for advice with this, as i don't think there's a lot of people who could give me useful advice on this (though it'd still be much appreciated if someone could), and i also just kind want to record what i'm doing here, just to get it off my chest.
