To downgrade, I used this guide: http://wololo.net/2016/01/04/3ds-system-software-downgrade-tutorial/ Then I attempted to use this guide to install rxTools: https://gbatemp.net/threads/tutorial-installing-rxtools-custom-firmware-3ds-and-2ds.390867/ However, when I attempted to launch homebrew through Ironhax, Ironfall stays on the 3DS loading screen (with the red 90 degree angles) forever when trying to launch. Thankfully, I can just use Menuhax2.1, right? Wrong. Every time I attempt to load it up, it just goes to the home menu screen like normal. Among other screwy things, the Internet Browser method fails and I can't load up Super Smash Bros for 3DS on my SD card without receiving an eternal black screen. How can I fix this? I wouldn't mind losing homebrew at this point if it means I can have a functional 3DS with all my saves and purchases, but I ideally I want to be able to launch rxTools.
