As the title mentioned, I now own a Japanese N3DS It already has the gateway exploit , and I already backed up a copy of the Sysnand, formed Emunand. I'm trying to update it to 9.0 for themehax for coldboot but I have no browser for using additional exploits. The 9.2J install files, RxTools 3.0 (but can't install/use), a DStwo are available. Attempting to use the RXtools using MSET results in a crash (but not gateway) But no cubic ninja copy and the lack of Cubic Ninja is hurting the set up process a bit. If ReiNAND has something similar to Devmode should I use that instead? Any advice would be helpful. and links to appropriate threads would be much appreciated. (The threads I've found are outdated or inapplicable) PS. Sorry for formatting, it's late here.
