I still stick to the fact that at a minimum you only need the keys.bin... and DeadlyFoez, lol.
First of all, if you can't access bootmii or priiloader to fix the brick or restore a nand dump, then you're going to need to use a nand reprogrammer one way or another to recover. So not having a dump of boot1\boot2 is immaterial because u can get it after the fact (and the same can be said for the setting.txt; i.e. wii serial #).
Secondly, not knowing which blocks are bad blocks isn't an issue if DeadlyFoez is repairing your Wii, he can just swap nand chips with his wii and run bootmii to dump the nand and determine where the bad blocks on the bricked nand are, not to mention he's got nand chips lying around with 0 bad blocks that he can use if wanted to. That's probably even unnecessary as Foez could just fix the underlying issue while the bricked nand is running off his tech wii (after using betwiin) using homebrew apps or whatever then make a working nand dump, then use betwiin again with the "bricked" wii's keys.bin to convert the working nand dump to work back on the wii it came from originally. I might not know all the details, but I'm pretty sure DeadlyFoez could explain exactly what to do to get around the problem of not knowing which blocks are bad even if u don't have his tech-wii or spare nand chips with 0 bad blocks.
My point is the keys.bin is the minimum that is required to unbrick a Wii. I may not personally be capable of repairing a fully bricked Wii with just the keys.bin (hell, I probably couldn't do it if I had a full nand dump! lol), but I am definitely capable of shipping my Wii to someone who is capable, like DeadlyFoez.
