Hi, can someone please help me with updating my 3ds' system version. I haven't used my 3ds for a while and it's on system version 11.15 with luma3ds version 10.2.1. I opened my 3ds yesterday and was trying to update the system to 11.16. The first thing I did was install the luma3ds 12.0 version using the universal updater app, which was successful but it caused my screen to freeze. I tried opening and closing my 3ds but the screen remained frozen (the theme bgm played so there was audio). After that I removed the sd card, put it on my pc, and manually replaced the 12.0 versions of boot.firm and boot.3dsx with their older versions from the 10.2.1 pack. My 3ds i back to working condition again but now I don't know how to proceed and I'm scared to make a mistake again. Should I install the 11.16 system version first and update to luma3ds 12.0 afterwards? What should I do? TIA.
