I'm trying to install Luma3DS, but I keep getting an error whenever I try setting up Decrypt9 with both methods. I'm using an old 3ds with firmware 4.5.0 and I formatted the sd card before starting.
For the non-browser method, it crashes and restarts when I go into the Nintendo DS Profile. The browser method crashes after trying to load one of the sites.
Double check you have the right files and clear cookies and history each time. That's all you can do I'm afraid.I've tried all of them. They all result in a crash.
