It fails to me.
The device tree named "gxbb_p200_2G_m8s+_k3_pro.dtb" it must be only for the KIII PRO that has an s912, it doesn't make much sense though, I'm not sure if this build also works in s912 devices.
No s912 Versions Here At LE.
I think Merziyas might have to Flash AceMax Android Firmware then do what you have done.

Hi jmartinez, I think I have the same device as yours. Which dtb.img file are you using? Because I didnt manage to get any of them to work for my device with the newer builds. Could you please share your dtb.img file with me? Thanks in advance.
