The other day I bricked my again, no big deal I though since I got bootmii and an infectus.
Went into bootmii and restored a NAND backup which I created (and tested) before, but after selecting the System menu or HBC the screen stayed black.
Then I used infectus to flash an image, which I flashed like 20 times or more and it has always been working, but this also didn't work.
So I took a dump of my non working NAND and I could see that the SFFS tables were 'cleared' the only things left were the root folders and the /sys/uid.sys file. I took a look at boot2 and indeed when ISFS_GetStats returns an error (except -104) it happly calls ISFS_Format way to go nintendo what a good idea!
I tried multiple images and so far none worked boot2 always formats the image.
so does anyone have any ideas?
