Hi guys. I have got a problem when downgrading my old 3ds. So it is an EU version old small one, with a 5.1.0E ofw. I have got it from a friend who didn't play it for like 2 years or more. So I have checked tons of the posts/guides. Most of them are telling me that I do not need a flash card(or gateway/r4) then I used the method without it. The problem is when I put the newest Launcher.dat in my 3ds' SD card root, and then try to open go.gateway-3ds.com. It freezes every time, sometimes with a red Launcher.dat loading__________, sometimes just a gray bottom screen then completely frozen. I have tried reset 3ds, clean cookies/history turn wifi on and off, restart 3ds. I can not get into the gateway menu. So any idea what is going on about my stuff?
