Hi guys, I am on the second or third lastest firmware (last update was in august or september). I extracted my otp, got CIA, the arm9 loader and luma custom firmware running. Is it save to just update to the lastest custom firmware? Do I need to update luma first? It was installed in August I followed the github tutorial (https://3ds.guide/). I have no sd card nand, but I got hourglass installed.
