To add the new created names you've to edit your locales language, for example, in case this you use Dutch the file is nl.json, for Italy is it.json, and so on. The locales files are located in /locales-obj/(your language).json of the Launcher's app. In my case of nl.json, open a text editor (Notepad++ on Windows, any editor on Linux), then find the line |-> {"$i":"airplane-mode","$v": <-|

Now take a note at the begin of the bracket { to the end of the bracket } including the comma, in my case this is: {"$i":"airplane-mode","$v":"Vliegtuigmodus"}, then create two new options (change "Trillen" to your language for "vibrate", in Dutch), then

then we place them like this:

To better understand all this, just watch this video:

After enabling vibration shortcut (read above) come back here. This is what we are going to get at last :

• Long press # button = silent mode on

• Long press # button, then switch on vibration shortcut = vibrate only mode

• Long press * button = silent mode off

Proceedings

1. Get a copy of the system.gaiamobile.org application's folder from the system:

adb pull /system/b2g/webapps/system.gaiamobile.org

2. Open the /js/sound_manager.js file in the application.zip using a text editor. Use a website like beautifier.io to read javascript in a more understandable format.

3. Search for "hash", you will see this line:

window.addEventListener('holdhash', this);

add this new line below it:

window.addEventListener('holdstar', this);

4. continue the search, you will see this:

case 'holdhash':

below it you will see this :

this.toggleVibrate();

change this.toggleVibrate(); like this:

this.enterSilentMode('notification');

5. Now just copy these lines from "case 'holdhash' :" to "break;" and paste those lines just below "break;"

it will be look like this:

now change holdhash to case 'holdstar': and change this.enterSilentMode('notification'); as like:

this.leaveSilentMode('notification');

Check attached images if you have confusion.

6. Push the app and its folder on the data partition, exactly in /data/local/webapps using a temporary root access:

adb push system.gaiamobile.org /data/local/webapps

7. Get the webapps.json file:

adb pull /data/local/webapps/webapps.json

And change the value of the system.gaiamobile.org app

• "basePath": "/system/b2g/webapps",

in this way

• "basePath": "/data/local/webapps",

8. After this change push the webapps.json file in its place and reboot the phone:

adb push webapps.json /data/local/webapps/

adb reboot
