So recently I'vd bought an o3DS with 2.1.0 fw. I followed the steps from the bottom of this site: https://github.com/Plailect/Guide/wiki/Browser-OTP The first problem I faced was the dissapearing of my Health and Safety app during the injection of fbi in part 4. I figured it was not that big of deal because I could still run fbi through the HBL. But when i proceeded to the step 5 I couldn't get the A9LH installer to work, it only makes my screen turn black, that's all. Could you please help me with that as I am a total hacking noob. I've no idea what might've went wrong. Thank you in advance.
