Hey there GBAtemp, First foray into CFWs since the good ol' fat PSP days, and am looking for a little guidance. I'd just like to start off by saying that I am only here as a result of finding partial or inconclusive information, and resorting to asking the community here for an answer. I was interested in doing this with my JP N3DS a few months before the N3DS launched in America, however, as you may recall there was no public guide on how to install a CFW back then (at least to my knowledge) To give you some background on my setup and tools: device: Japanese N3DS (small one) sysnand: 8.1.0-0J emunand: GW3D 10.6.0-31J cards: Gateway Red Card (updated to 3.7.1), Sky3DS (blue button model) What I am hoping to do: Install a (U) emunand on my JP N3DS. What I have managed so far: - Used my Sky3DS with a Cubic Ninja (J) rom to boot into Gateway (this was due to the N3DS forcing an update request on the 8.1.0 FW whenever I wanted to launch the browser, regardless of configuring the DNS or date) - Backed up my sysnand - Created my emunand, and updated it - Did the nvram install so I could boot into emunand through the DS profile exploit What I've skipped: - Anything regarding the Gateway blue card, due to getting kicked out of booting it since it reads out as a (U) game I think? - Installing browserhax or menuhax due to the aforementioned browser hangup. From what I understand, I need to use something called CIA to replace a bunch of J-designated files with their U variants, and then perform a system format? I guess my main misunderstanding is how do I go about this within the context of my setup, and if there is in fact a guide for doing this that I have clearly missed in my searching. Thank you all in advance.
