So I have an old 3DSXL, version 7.2.0 - 12U. No flash cart, cubic ninja, or zelda. I followed this thread: https://gbatemp.net/threads/tutorial-installing-rxtools-custom-firmware-3ds-and-2ds.390867/ to a "T". I've accessed rxTools and injected FBI (all the way to step 4a, I even separated the nands). But it says I should have an FBI app on the homescreen and I do not. There are now 3 black squares where gifts were before and I can't access rxTools from emunand, it just freezes when the bottom screen glitches. This is so frustrating! I've been at this for some time now and just when I thought I was done, I'm not. Someone please help, any advice would be appreciated. Thank you!
