I have a 3ds (old one) with 7.1.0-0E firmware. However, it was 3.0.0-0E before I upgraded via a 3ds game. Problem is, I couldn't access the internet browser without an update. So I decided to update, but not completely (as some people said that would make the browser appear). I had a 2 day warranty on the 3DS, so even if it was bricked, I could return it. So I let it upgrade till around 60% and then shut down the 3ds, that worked. I got the internet browser while remaining on 7.1.0-0E. However what I didn't take into account, was the internet browser version. It's on the latest browser version: 1.7610 which patches the browser exploit. I don't have gateway, however I do have SupercardDSTWO. Is it possible for .CIA files to be installed, using a .nds program? So without getting gateway, sky3ds or cubic ninja. Is there any way for me to make my 3DS CFW?
