On android 8 I found the dtb in resource.img
On android 9 I can't find the file resource.img
The original ROM of h96 max + is bad, I found a good one but it is for another device having the rk3328 chip.
I need an android dtb of h96 max + to works the onboard wifi and onboard bluettoth on this rom.
I managed to reassemble the rom with the dtb of my h96 max + the rom starts up and works but they don't work onboard wifi and onboard bluetooth, I'll try other solutions.
The easyb dtb works well with powerled indicator, ethernet, usb wifi, usb bluetooth, hdmi sound,
CEC: not tested, the video is not very good. I will confirm if the video is better with other dtbs
