Boost LG G3 Volume

How to Boost LG G3 Volume

Once the device is rooted, you need a root file manager to make some changes on your system files. We recommend you to install the root browser on your device.

Step 1. Now run the root browser application on your phone and navigate to /system/etc directory and open it.

Step 2. Now look for the following XML file depending on your phone model:

>> mixer_paths_qcwcn.xml (D855)
>> mixer_paths.xml (D851 and other US Models)

Step 3. You have to make some changes in these files. So first take the backup of your file and save them in some safe place. In case the mod does not work for you, or you wish to restore volume value to stock later, you can copy the original files back and fix file permission.

Step 4. Now tap and hold the XML file and select Edit option.

Step 5. Change this red value to your liking
