I decided to do two different install methods, an easy method and a more advanced method.
The easy method ONLY allows you to use the MG4 Control application, the more advanced method opens up the path to sideload more applications.
You do not need to keep the USB plugged in post installation.
SE owners see notes at bottom
For the easy method you will need the following file:
MG4 Control: https://github.com/SliDeeN/MG4Control/releases/download/v2.6.0/MGControl2.6.0.apk
Copy this files onto a USB stick (A type, left port on the car)
Then start car, plug into the car and watch this video: https://photos.app.goo.gl/E1Qro4qAkR3tVzSt9
For the advanced method:
Download the following files
MG4 Control: https://github.com/SliDeeN/MG4Control/releases/download/v2.6.0/MGControl2.6.0.apk
MG4 Swipe_NovaLauncher: https://github.com/Tommasov/MG4_Swipe_NovaLauncher/releases/download/1.2/MG4_NovaLauncher_Swipe_1.2.apk
Nova Launcher: https://teslacoilapps.com/tesladirect/download.pl?packageName=com.teslacoilsw.launcher
Copy these files onto a USB stick (A type, Left port on the car)
Then start car, plug into the car and watch this video: https://photos.app.goo.gl/jyUNEAwnPckBKcus5

I better suggest that modifying your car could affect vehicle software update compatibility and warranty. Use at your own risk.
With that said the process to uninstall the application/s is easy and if people want to know the method I can do a video on that also.
My car is a MG4 XPOWER, if you are using another version of the car I believe the app will still work as it supports SWI131, SWI165, SWI69, SWI133 and SWI68.
If you load this onto your car and you get a "Unknown Firmware Version" warning, accept it and test using the different SWI versions, one might be correct for your car or most/desired options will likely work. Feel free to DM me if this happens.
P.S. Sorry for the poor lighting, poor focus, poor narration.. I am not a youtuber and don't have good kit for doing this
If anyone is local to me I am happy to do this for free if it seems too intimidating, unfortunately it is not something that can be done remotely.
