Several people found it hard to gather all scattered information in this thread to install 1300R63 (Trophy release) on a MG4 SE 2022/2023.

Risks involved:
I’m deliberately not providing an overly detailed step-by-step guide because I want users to fully understand what they’re doing.
If the procedure outlined below seems unclear, it’s a sign that you might lack the necessary knowledge to perform the upgrade safely. Feel free to ask questions, but avoid attempting anything without a clear understanding. Proceed only if you’re confident in your abilities.
Be aware that this update is entirely outside of MG’s official procedures and is not covered under warranty.
Filesystem structure:
When running a SE Release:
Place the update file (usb_ota_update.zip) at the root of the USB stick.
When running a Trophy Release:
Place the update file in a folder named AVN_MPU.
To avoid confusion or repeated file handling, you can place the update file in the AVN_MPU folder and also copy it to the root directory of the USB stick. This way, the file will be ready regardless of the release you're working with.
Procedure to update to R63:
while on a SE release
- Go to the engineer menu / Select Upgrade AVN-SOC (This updates the MPU to 1300R63).
- Upon restart, validate both system and navigation
- Go to the engineer menu / Select Upgrade Infotainment System ECU (This updates the MCU to version 68.4.3.0; the latest version is unfortunately not available).
- Upon restart, go to system > privacy policy and swipe down to enable navigation and online music.
At this point, your system should be operating normally, excluding navigation and built-in voice recognition. There should be no issues with AA/CP.
I currently do not have the VR files, so it is not possible to make the voice recognition functional.
Installing maps:
If you try to install the latest maps straight, it will fail.
I've found a workaround, but it's a wee bit of a hassle as it involves installing several maps in a sequence.
The process involves:
Installing Australian maps as a bootstrap
Installing European 22Q2 maps, it's an older version of the maps without an MD5 check.
Updating this version to 2023Q4 maps, which is the most recent version available.
The Australian maps are quick to download, unpack, and install. After installation, reboot the system. These maps are not expected to work, and you’ll encounter an error message if you attempt to launch the navigation. The purpose of installing these maps is that they reliably complete the installation process and generate a success flag, which is required to proceed with using maps.
Next, install the 2022Q2 maps. Around 95% of the way through the installation, the update will fail during the file verification step. To avoid displaying a failure flag, do not acknowledge the error. Instead, press and hold the Home button for 10 seconds to reboot the system.
this process lasts about 45 minutes
After the reboot, navigate to the app, and everything should function correctly (though the maps will be outdated).
To update to the latest maps, once 2022Q2 maps are working, you can install 2023Q4 maps. Again, the update will fail toward the end during the MD5 check. Simply reset the system by pressing and holding the Home button, and that’s it!
That's another 45 minutes worth of your time by the way!
After rebooting the system, check the version in the navigation options to confirm the update.
