Hi there! I'm going through hell with all this rxTools stuff... Question is, I accidentally upgraded my sysNAND from 7.2 to 10.7 using a japanese o3DS XL (LL). I still have my backup of 7.2.0-12 SysNAND, is there some way to going back to 7.2 firm? (9.2 is what I'm truly aiming for of course) I know something about using Zelda OoT, but you need two 3DS's right? Nobody in Japan would lend me a 3DS for that, and their 3DS firm are 99% of the time upgraded to last version. Also heard something about Powersave Action Replay, but don't know how it works, if it works. And yeah there's also Cubic Ninja?, a game with magically the same price as a new 3DS! ^^ I don't know what to do anymore... Thank you very much for your help! Edit: Mamma mia... Still some problems for me! This time trying to use Powersaves on my japanese copy of Zelda OoT, thing is Datel Japan is closing, and is not longing supporting Powersaves in Japan, so I have some Powersaves soft (US) region problems detecting my Zelda OoT (J) copy, http://www.neogaf.com/forum/showthread.php?t=1006237 | https://www.reddit.com/r/PokemonPlaza/comments/2f9p7n/japanese_powersaves/ Looking at this http://www.gamefaqs.com/boards/997614-nintendo-3ds/69081951 I wonder if that 'Cyber Save Editor' would work? http://www.amazon.co.jp/dp/B00LBSLQ...lid=3CRL2SOQVE6WX&coliid=I3PRFCLODTKHS7&psc=1 Even if it works, it costs more than two times the price of Powersaves, plus I already bought Powersaves... Edit 2: Powersaves US works with JPN Zelda OoT3D, can't access cheat codes but you can do what really matters: backup your save file and hax it to access homebrew.
