IR Remote media buttons not working!

[hornet]

Hi guys,
I hope to find help here..I searched almost every post about this, but I did not find a solution that works.
I have a problem with media buttons on the ir remote control, do not work.

Device does not detect any KeyEvent (Tested with KeyEvent Displays from GooglePlay) when I press forwarding, play, pause, stop...All other buttons work perfectly.


What's interesting is that I have another device with another firmware (Android is the same on both 4.4 ) where everything works smoothly. I can send pictures of another device.
On the other device, when I press the button "KODI" the app is running.

I can upload the firmware from both devices, if necessary.

I've tried:
- Compare and copy all different files ( \system\usr\keylayout ) from a device where I have no problems with media buttons.
- Copy kernel ... And repack frimware.

But this did not solve the problem.

Does somebody know how it is programmed this buttons... If I want to run another program when press "KODI", how to change it?

Thanks in advance. Sorry for my English.
