I tried getting help in a few other threads but It's probably easier to sort this out in one thread and explain my situation to prevent further confusion. Exactly a year ago I've wanted to install CFW on my 3DS to play Monster Hunter Cross. I used an old version of the guide hosted on github and I did almost every section except for installing arm9loaderhax, because I was anxious to play the game and thought I didn't need it. Fast-forward to the present, the 11.3 system update came out and I installed it so I can play online on Monster Hunter Double Cross. However I didn't realize that Cakes ver. 138 wasn't compatible with 11.3 (I initially thought that the rainstorm outside corrupted the update). Now my emuNAND doesn't boot up and I don't even have a recent backup. I've come to the conclusion that this is probably the best procedure to get my emuNAND back up and running normally 1.) Install arm9loaderhax 2.) Update my CakesFW to the latest version I hope doing so might make my emuNAND boot normally and everything is back to normal. The thing is, I've gotten really confused when people give me answers on how to install a9lh. They say that I must follow the whole guide to install it but that can't be right. I've done the whole thing a year ago so I just need to specifically install a9lh like I was supposed. I can't install Luma since I need to re-access my lost stuff on the emuNAND and I don't think following the guide from the start would be that safe for a 3DS that already has homebrew and all of that crap. I'm just asking for how to install arm9loaderhax itself and that's it and also how to get everything back to normal too. I need helpful instructions and pointing to the main guide like it's the Bible is not going to help. This whole ordeal is having an effect on my mental health and I need to get it out of the way of my life before it takes its toll.
