Take Backup Before installing:

Replace this line "X:\platform-tools\Backup\mixer_gains.xml" With the Backup folder you created before

            adb pull "/vendor/etc/mixer_gains.xml" "X:\\platform-tools\\Backup\\mixer_gains.xml"

Replace this line "X:\platform-tools\mixer_gains.xml" With the exact location of the new "mixer_gains.xml" file inside the in.Call.Fix.By.KEMOZ.zip

            adb push "X:\\platform-tools\\mixer_gains.xml" "/vendor/etc/mixer_gains.xml"

Make sure to not pull the old mixer_gains.xml into the platform-tools or it will replace the new mixer gains file you extracted instead Make sure to pull into the backup folder you created to avoid replacement

Done.
