I went to the web site. After I hit enter my screen seemed to freeze and nothing happened. I hit select like the instructions said. I waited a bit and rebooted by holding power button down. Now when I hit power the blue light comes on but screen is black. Also in a9lh on sd card I dont see OTP.bin. Please help.

edit: I removed sd card and it worked but everytime I go to the github site my 3ds freezes

edit 2: I got it working. Not sure what the issue was but its working now.
