Thanks for this awesome guide! I just got Haxchi and HBL successfully installed on my 5.5.2U. I used Brain Age and despite all the warnings about unstable 5.5.2 exploit, it worked on the first try for me. Some noob questions before installing CBHC or any games: - Is it safe to connect to internet, play online, and update games on CFW? Any reports of NNID bans like on 3DS? - If I'm planning to use USB Helper and WUP Installer to download/install games and updates on a USB HDD, do I still need to load CFW to play them if I'm not installing any DLC for that game? Do all the games still show up on both original sysNAND and sigpatched sysNAND (Haxchi CFW)? - If I later do install DLC for a game, does the whole game then become unplayable on original sysNAND?
