There is no file specific to my box model. It has an s905X3 CPU, but all dtb files for it don’t boot. The S905X2 CPU has very similar specifcations what is probably the reason, why the g12a-x96-max.dtb file is working.
I wish manjaro team would provide a file for my device
We do not really work on tv boxes. It is the community users who work on it when they have a tv box which they think can work with existing dtb.
I have no idea which box you use and what chips are used inside, nor anyone have a sample device to play around with.
You can ask manjaro community users who might have the exact same device to debug things on manjaro and get manjaro working on it.
I hope someone from the community would be able to help you with manjaro for your device. This is cause the device is already discontinued so only those who already have the device can test it and report back the issues.
I know it has been a long time but I tried installing Manjaro on my T95 max plus like you did. The box is already “SD-card-boot-enabled”, as Emuelec starts flawlessly from a microSD.
So I downloaded the same Manjaro-version like you did, burned it with Etcher, changed uenv.txt to use meson-sm1-sei610.dtb…
But every time I try to boot with the SD card entered, the box boots into Android.
