Manitoba, CanadaIt works the same as on PC, but you have to time your jump presses to be as soon after you hit the ground as possible since we don't have a scroll wheel. If you don't know how abh works, you start by jumping backwards or turning backwards in the air, crouch in the air and stay crouched throughout, and tap jump right as you hit the ground, then continue timing your jumps to build up more speed. I don't know how to start an afh from the ground on xbox, but if you already have some speed like in the chamber 10 flings, the only difference between for afh is that you need to hold backwards on the movement stick to and look forward, while crouching and timing your jumps right after you hit the ground. I also like to bind my jump and crouch buttons to the shoulder bumpers so I don't have to use my thumb for both of them on the buttons. Join the discord to get even more help.
You're playing on the latest version of portal, so you can only rotate the radio on your first playthrough of the game because it changes the radios after you complete the game for the transmission received achievement. If you play on the old version used for high level oob (version 3420, not recommended), it will always have the rotatable radios because it was released before the transmission received achievement. Rotating the radio also isn't necessary for any trick.
from the game rules: "All runs HAVE to be submitted with some sort of proof in form of a video or demos. In case of suspicion demos can be requested by the mods. Videos have to show the full run from start to finish. Video must be hosted on a permanent video platform, such as Youtube or a Twitch Highlight. Temporary platforms such as Streamable or your Twitch VOD are not acceptable. If you are submitting Time without loads with only video proof, the video has to show Livesplit comparing against Gametime throughout the entire run". It's also advisable to install Source Unpack Version 2.4 at https://sourceunpack.gameabusefastcomplete.com/ because the newest steam version has some glitches patched. You should also probably watch the setup guide and how to submit a run in the guide section.
