    I've felt like I need more volume from the speakers, so thanks!

    I'm having issues with opening the mixer_paths with root explorer, however - I cannot open the entire file because it says it's too big. I'm also unable to find the file through the file manager that comes stock with the phone.

    It's already fixed mate..
    Thanks for your support

    When I see the OP it says this

    . backup your original mixer_paths_qcwcn.xml (copy to sdcard, rename to mixer_paths_qcwcn2.xml, etc, etc)
    3. open mixer_paths_qcwcn.xml

    Your two posts stating the correct path is

    The correct one should be mixer_patah_qcwcn.xml

    Trying to do this hack. But as you can see, the file you are telling me to edit does not exist in my phone. Now what?

    Try editing the mixer_paths.xml

    I'm using International D855
    And try to change the speaker value to 90
    If it works just let me know

    I will change the OP for D851 version guide
    If it works could you send me your mixer_paths.xml



    i don't have this file , mixer_patah_qcwcn.xml
    but i have this file, mixer_paths_qcwcn.xml and upon checking the lines of those "green" which we have to edit they are the same.

    Yeah that's my autocorrect fault

      I made a flashable zip to make ur life much easier

      Im having the same issue! I did it step by step but after I tried to reboot I'm stuck at the Verizon Splash screen.
      Can anyone please Help, I need my phone lol
      My phone is rooted but do not have a custom recovery installed.
      Thank you.

      (Great! all for wanting louder sound! lol)

      you need to download and install LG Tool, then restore your phone to the original factory state using this tool, then root again etc.

      didn't your mother tell you not to play with fire unless you have nandroid backup?

      Okay so I had to give 920 editor root permissions and it worked.

      Also, the AT&T D850 version requires you to change the mixer_paths_qcwcn file, not the other one. Rebooted and now it's working perfectly as intended.

      If only NYC trains were quieter, I wouldn't need to do this!

      Hi, I've had the same problem and just wanted to ask, How do you run text editor as root user?

      using 920 text editor -> preference -> other -> try to run as root
