(Bad english warning) I'll try to make this as short as possible: I'm a noob at all this homebrewing stuff, but I found out that my O3DS XL could be downgraded to 10.4 to 9.2. I was very happy, since I've been wanting to use CFW's for quite a while now. After a lot of trying and reading, I managed to downgrade it sucessfully. The thing is, after that, I tried to install some CIA's on my console, there is a Netflix program that I wanted to try out. I did so much stuff that I don't even remember what I did. I know I "installed" (don't know the correct term) an emuNAND and Rxtools too, but I couldn't install CIA's no matter what. Now, I want to undo everything I did and start it all over again, starting with a "pure" 9.2 console and a clean SD card (my console still works normally, btw). What exactly is the best thing to do? 1-)How do I undo all the sh*t I may have done? 2-)Which CFW's, Homebrews, EmuNANDS or whatever are the best to install? What do they do? 3-)How to install them? 4-)I have a few Legit CIA game files somewhere in my computer. Would I be able to install them? Play online? Use Eshop? Update software? Sorry if this got too big, I looked all around for answers like this, and I'm not stupid, but this thing is just way too hard for newcomers like me, and I wanted this thread to help other people like me as well. Please help. Just link me to the right places if answering is too hard or tedious. Thank you.
