Sorry, I don't really know what I'm doing. I just tried do the browserhax by changing the date and time, but it just crashed. Or are you talking about something else?
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.
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.
