Nope, to use NTR, you use the 9.6/10.2 firmware.bin file, which have svcbackdoor, etc...
Oh, okay! So the patches that they're adding to Luma3DS to restore svcBackdoor are meant to fix it for vanilla Luma3DS with no firmware.bin?
edit:
wrong and right. the latest commits do fix it. but you dont have to compile it yourself http://astronautlevel2.github.io/Luma3DS/
Yeah, I found that like five minutes after I posted on a reddit thread. Thank you!!
