Here is the proper file for 4330 and 4334
Bluetooth can't get it to work yet, I don't know if it depends on a new dtb file or the kernel. Or just need to add the driver, but I could never get it to work.
Anyway, my tvbox 99% works, everything works perfectly except the Bluetooth and being able to install Libreelec in the internal memory.
I hope the developers can help us here.
