I installed menuhax using the v2.2 installer included in the starter kit for 3ds homebrew (detection type is type 0) and it won't work. Idk what to do. I'm using an O3DS 10.3. Any help?

Sadly I can't download it as the tablet I use to get apps and things is bricked now. Also there was theme management data on my sd card so should I reinstall it?You need to have viewed the themes at least once to make the exploitable theme file for menuhax to install.
Also I highly suggest checking out A9LH instead of keeping with Menuhax

Fair enough.Sadly I can't download it as the tablet I use to get apps and things is bricked now. Also there was theme management data on my sd card so should I reinstall it?
I installed everything again and didn't delete the extra data and everything and it still didn't work. Surely I'm doing something wrong.If you haven't viewed the themes, simply view them and it will make create the files in the Nintendo 3DS folder for your themes. From there, just run the Menuhax installer and it should work.
I reinstalled again and it turns out I needed to NOT create theme-management data OR visit the Home Menu, otherwise I have to install everything again. Now I have to use HANS to open games and stuff.I installed everything again and didn't delete the extra data and everything and it still didn't work. Surely I'm doing something wrong.
