@Scrooge69 Welcome to the armbian world and your first post in the forums.
I unfortunately don't have much information in response to your questions. balbes150 who created the builds referenced in this thread has moved his focus to other projects (the StationPC M1 and P1 boxes). I don't own a rk3328 based device so I have no personal experience with them. If you look at the recent activity in this thread there isn't anyone actively engaged currently supporting boxes like the one you have. The best I can recommend is to try using the images linked in the thread and try things out. Since you are puttimg the images on an SD card it won't hurt your device to test and experiment. (I wouldn't recommend installing anything onto your emmc memory however).
A test version of the image Armbian for TV boxes on the basis of RK3328. Tested on MVR9

All basic functions work. For running. Download. Unpack. To record on the SD card. Connect the SD card to TV box, connect a keyboard and mouse. To turn the power on the TV box. The system should start within 2-3 minutes. You must perform the initial configuration of Armbian.
The system of choosing the correct dtb has changed.
Please note, now it should be done on a different principle (files do not need to be copied).
To select the desired dtb, you need to change the line in the text file "/extlinux/extlinux.conf". In the line "FDT" you need to change the name of the file that the system will use at startup. The list of available files (names to specify in the configuration) can be found in the "dtb"directory. If you do not know exactly what file you need , you can enter all available names in turn and check the operation of the system. In accordance with this, the system installation script in eMMC has been changed. The steps to install the system on the eMMC remain the same.
Added a utility to full backup and restore the entire eMMC "ddbr". Checked mode the backup MVR9. Now if you try to check the recovery mode.
The order of installation in eMMC.
1. Download, unzip and burn the image to SD card.
2. Start Armbian on the TV box and perform the initial setup of the system.
3. If the system works correctly and you are satisfied, run the utility "ddbr" and create a full backup of eMMC (this is a prerequisite).
4. Rename the file "/boot/mvr9-uboot.img" in "/boot/uboot.img".
5. Run as user "root" script "/boot/create-mbr-linux.sh"
6. To run the script "/root/install.sh"
Pay attention to the correct operation of the installation procedure need to comply strictly with the order of the steps.
