Well, for lack of knowing where else to ask, I present you with my little cfw-fuckup: (complete and utter noob here)
TLDR below.
~2 years ago, I got ninjhax1.6 up and running after updating to 10.something by accident.
That should be arm9loaderhax, right?
Yesterday, I updated to 11.3 after 2 years of almost not touching my 3ds. ( i didn't remember anymore that i had ninjhax as an entrypoint and homebrew stuff on my 3ds)
And then went through with this : 3ds.hacks.guide/get-started
It all worked out fine(the whole setup, and installing freeshop and trying it out)
But now I do encounter a problem that makes my system unusable, though not bricked.
3ds boots up normally; however upon arriving in home menu, lower screen is unresponsive. the console "tries" to do the following by itself: open home menu-settings. or more likely, the touchscreen is bugging on that top left corner, because it keeps "flashing", as if I would be tapping there.
Can't navigate anywhere by touch, arrows sometimes work. (Both with and without SD card inserted)
If i can get over to Lumaupdater(or anything else for that matter), i can run it. As long as the app does not need touch-inputs.
What i tried:
to run LumaUpdater 2.2 Restore: --> CTR-NAND error ("something critically wrong C8804478")
Sysnand restore in gm9 did work but didn't do anything. ( I did that first)
Presumably, my failure in upgrading AL9H to B9S, and instead upgrading like I did not have anything installed, caused this.
Now the question is: is this right and if so, how do I get that shit working again?
My next take would be 3ds.hacks.guide/troubleshooting and the TWL_firm.cia part.
Is that the solution? Q_Q
TLDR rundown;
-*probably* had a9lh (ninjhax1.6, installed 2016)
-did the straight upgrade to luma (b9s) *without* al9h to b9s
-installed freeshop cia, downloaded some themes.
-deleted those themes
-tried out anemone(came with luma setup) and installed a theme there.
-powered 3ds off and went to sleep
-touchscreen is bugging out on the top left corner, kind of incapacitating the system
Thank you for reading this and helping me out :>
