Yes, you have screwed up. The guide even told you to make sure that you were in emuNAND before you updated. EmuNAND9 can only be accessed on a 9.2 sysNAND, iirc. The only way to get Luma3DS now is to either get a hardmod or find someone else with a CFW'd/A9LH'd 3DS to do the Fieldrunners aka DSiWare Downgrade exploit.Guys, I probably messed up...
I've tried to use this part of the guide: https://github.com/Plailect/Guide/wiki/Part-3-(RedNAND)
At the very end I've tried to run Luma3ds and update it - turns out that my SysNAND was updated to 11.0.0.33-E.
I've installed menuhax and am able to access homebrew launcher (used browser+website to access it) but I cannot access EmuNAND9 to restore the backup of 9.x to sysNAND.
Did I screw up very hard? what can I do now if I want to install luma3ds?
