I was finally able to get RxTools to at least boot on my Old 3DSXL. My SysNAND is 4.4.0-10U. I am currently using Gateway running EmuNAND 10.4.0-29U. I can successfully boot to RxTools using the internet hack, and can load RX3D 10.4.0-29U. Successfully replaced the Health and Safety app with FBI on both SysNAND and EmuNAND, but I have to boot into RxTools and go back to SysNAND before it will work in SysNAND. Works fine in EmuNAND. Using FBI on both SysNAND and EmuNAND, I can install CIA files, but they crash in both SysNAND and EmuNAND. I've installed the patched AGB jank after deleting the previous one, and have tried booting into DevMode from RxTools, but it still shows me OFW 4.4.0-10U, and GBA games refuse to boot. When I tried to install DevMenu 6.2 on SysNAND, it installs, but hangs at the Nintendo 3DS screen. Been at this for hours now and am at wit's end. I'd very much appreciate any assistance anyone could offer.
