 adb remount
 adb push user.js /system/b2g/defaults/pref
 adb shell sync && adb reboot

 1. adb root
    adb remount
 2. Pull omni.ja from DUT
    adb pull /system/b2g/omni.ja
 3. Unzip omni.ja 
    unzip omni.ja -d Omni
 4. Find ril_consts.js in Omni/modules/
 5. Open ril_consts.js and update this.DEBUG_ALL = false to true.
    sed -i 's/this.DEBUG_ALL = false;/this.DEBUG_ALL = true;/g' Omni/modules/ril_consts.js
 6. cd Omni, zip all files

MMS debuging

• Add 'pref("mms.debugging.enabled", true);' to turn MMS debugging on

• Use the patterns above to change either the pref.js in the user profile or the user.js for the system: http://kb.mozillazine.org/Firefox_:_FAQs_:_About:config_Entries

• Real time turning wifi debug on ( you will need netcat ( http://netcat.sourceforge.net/download.php ; http://www.catonmat.net/blog/unix-utilities-netcat/ ) ). You will also need to work with a version that has the simple remote js console. Patch listed here: ( bug 723391 )

 adb forward tcp:9999 tcp:9999
 netcat localhost 9999
 navigator.mozSettings.createLock().set({'wifi.debugging.enabled': true})

• to turn it back off, just set it to false:

 navigator.mozSettings.createLock().set({'wifi.debugging.enabled': false})

Source : bug 806611

• to turn system system updates off; set gaia.system.checkForUpdates to false
