I installed arm9loaderhax today. I successfully did part 4 of the guide on the GitHub, and got my otp, and followed part 5, step by step. when I got to the safea9hl installer in sysnand. Then, the app told me it installed successfully, and it told me to press any button to reboot. I did, and it rebooted with just the blue light on. then I tried turning it on again, unsuccessfully...help!
