I tried searching through other posts on this forum, but none solved my problem. I can't boot into sysnand anymore. The same error below keeps appearing. As I saw in some posts suggesting to update everything (atmosphere, hekate, etc.), I did that, but still can't boot into sysnand. The emunand continues to work perfectly. I also tried formatting the microSD and putting all the new files, but then both emunand and sysnand stop working (I had made a backup of the microSD before formatting, so I recovered the emunand, but still sysnand won't work in any way, and I don't have a backup of the original nand before this error). Does anyone know how to recover my sysnand from this error?
