[MOD] [ROOT][KK] Updated Boosted speaker
New KitaKat method scroll down to bottom
First of all all credits go to sil0 and freebee269. This mod is originally for the LG G2 but it works for the G FLEX. Please visit the original thread posted by sil0.
This mod will increase your speaker volume considerably. As with anything else only you are responsible for any bricks.
Lets start with the mod.
First of all you must be ROOTED.
Downoad any root explorer of your choice. In this case i used 920 text editor from the play store. Its free.
Make sure you have root permission in your explorer and navigate to system/etc/snd_soc_msm. There you will find a file named snd_soc_msm_Taiko. Open it. You may need to choose text editor if you are using a different file explorer.
On 920 text editor navigate to line 5521. 60 is the default percentage for speaker volume, you may change this to your liking. Personally i have it set to 67, its loud without being distorted. I dont recomend anything over 85. Now do the same for line 5530.
If you are using any other file explorer navigate to:
Comment "speaker Rx device"
Scroll down and you will see RX7 Digital Volume' :1:60. 60 is the percentage output on you speaker.Change the value to your liking. Scroll down and you will see another RX7 Digital Volume line and change the value to match the value you chose earlier.
Save changes and restart your device.
Tip: A soft reboot did not apply my setting please do a normal restart.
For all the kitkat users, the procedure is pretty much the same.
Find etc folder in device
click on mixer_paths.xml
Find "<path name="speaker"
Raise the number on the RX7 Digital Volume
Save settings and restart the phone.
I have mine set to 68, pretty loud i even have to turn it down with some songs.
if this was any help.
