Ok, I finally bought an already hacked O3DS. As I'm in Peru, it costed me almost an entire paycheck, but it was worth it.
I have some issues with it, though, and I would love that you guys help me as I know next to nothing of the 3DS scene. All of these questions are product of my 2-day research on it, I haven't touched the WiFi switch at all.
1) It came with EmuNAND and RXTools. As far as I understand, RXTools (and EmuNAND itself) are outdated and it's recommended that I actually install ARM9 and Luma into the SysNand. Would I have any problems if I do that? The SysNAND firmware is 9.2.0.
2) The seller insisted that the 3DS should came with the leaked Pokemon Moon .cia pre-installed as a bonus in EmuNAND. I'm not sure if it is the leaked version or the actual FreeShop version. To be sure of it (and due to the recent banwaves), I want to delete it as soon as possible and resume my game later, but I don't want to lose the save data (I found a legit shiny Yumgoos). What's the process to backup savedata from EmuNAND and restore it into the new shiny Luma SysNAND?
3) It came with FBI, and that installs .cias, right? Haven't tried it yet, but I'm assuming is similar to the Wii's WADManager? I read something about TitleKeys.
4) Right now, when I turn on the 3DS a few buzz-static screens appear and a "CFW selector" with the words "Yakareando" shows up before auto-loading the EmuNAND. From what I infer, the seller followed a tutorial to install RXTools from a colombian website. The only way to load the SysNAND right now is to turn on the 3DS with the SD card removed. As far as I'm reading, for the Luma install guide I need easy Access to the SySNand, so how do I turn off the AutoBoot? Even better, what files should I delete? I'll post a pic of my SD folder later.
5) In the guide of the Luma install, I don't understand the 4th step in the "Install Arm9loaderhax" part. What exactly am I backupin'? The guide says that before doing this step I should transfer my EmuNand content to the SysNand and ignore step 1, so after that should I do step 2?
6) My endgoal is installing FreeShop. In all of these questions, what are the bricking risks?
I know I'm asking alot but this little machine costed me quite a handful (I'll be in debt for the entire next year) so I'm pouring all of my heart onto it. Thanks in advance.
