I attempted to upgrade my 9.2 N3DS (emunand) to 9.5 using sysupdater and the 9.5U cia files. As far as I know I had succesfully unlinked emunand and sysnand. Sysupdater ran and completed perfectly, no errors, but then began a boot loop that happened regardless of whether I was attempting to boot into sysnand or emunand. Anyone have any thoughts? I'm confident I had the right cia files for the correct region.
