Ok so I finished setting up dsiware and I have partially downgraded my 3ds by downgrading my kernel and firm version to 2.50-11 (AKA 10.4 Firmware). I'm trying to use sysupdater to downgrade to 9.2 just like I did on my other o3ds (just did this 2 nights ago) using the same files. My problem is that every time I run sysupdater made for 10.4-10.7 I get a black screen and it wont bring me to the sysupdater menu. I tried getting plaisysupdater after this. It loads the menu, but whenever I try to downgrade it gives me the error "did not get am:u handle... attemtping svchax..." and then it just sits there forever and nothing happens. So my problem is that whenever I boot sysupdater it goes immediately from red (bottom screen) to a black screen (both screens) instead of flashing many colors and booting up to the menu. Does anyone know a fix? I am 100% on the 2.50-11 kernel/firm version so this should be working. Could any files on my sd card interfere with the sysupdater homebrew app? My "updates" folder has the correct files for 9.2 as I just used it to downgrade my other o3ds 2 nights ago.
