need original "audio_policy.config" file for huawei G6

hi guys
i have a huawei g6 rooted , i had a problem with voice and video call in Line and viber and ...
so i find a guide in xda that can edit the audio_policy.config and the problem solved.
after that i flash my phone and this time i replaced the audio.config file with an edited version in that post . after that my Bluetooth has a problem , i can pair it with all devices but when i want to transfer audio to them , my phone will crash and reboot :(
is there any body there that can give me the original audio_policy.config file of his phone . :eek:

you can fine it in device memory-> etc -> audio_policy.config

and i think you need a root explorer and root device .:rolleyes:

i need it very much plz help;):good: .
