I had to figure this out myself but basically if you bricked (lost access to) your 3ds emuNAND by updating to 11.3-11.5 there are no worries, you can transfer to b9s and luma CFW much easier than you thought. You might have checked 3ds.guide and thought you had to use a guide for your emunand version but actually you should do the steps in sysNAND. The sysNAND version is 9.0-9.2 with rxtools. I could paste the text from 3ds.guide to here but that would be unnecessary since there's probably only a few people who didn't check gbatemp before continuing to use rxtools (that's me ). so use the guide from here and I'll add some extra steps to do when you are in this situation. You need to make sure you are in sysNAND (of course) and have selected the guide for 9.0-9.2 which will be the soundhax guide. then you will have to disable menuhax by either changing your theme or removing the menuhax from your SD card (menuhax is outdated, don't use it) make sure you have plugged in your charger make sure you do follow the 3rd step (which is to copy the contents of starter.zip to the root of the sd-card, make sure you replace the old one) because it is updated and the old homebrew starter kit doesn't load .3dsx files correctly, and crashes often! when you have followed the guide to the point where you have to update your system, do this first and foremost if you want to move the contents of your emuNAND (including all cias and saves) to the luma sysNAND CFW !! do the last steps of the original guide and voilà! you can now be part of the gang!
