Howto disable Emergency call button on lockscreen - Android CyanogenMod

‘Emergency Call’ button on the pattern lockscreen is really annoying for me, so I decide to remove them. I’m using CyanogenMod and I was able to find place in source code, where is defined.

Patching was pretty simple:

• start with CaynogenMod Developer Resources page and figure out, howto build your own custom ROM
• synchronize your repository with repo sync command
• build your first custom ROM witg brunch command (it will take about 1 hour on fast computer, 8+ on slow computer)
• push your custom ROM to your phone and functionality
• remove class EmergencyButton.java
• remove reference to EmergencyButton object from EmergencyCarrierArea.java - commenting out whole protected void onFinishInflate() method is the simplest way
• remove XML tag from keyguard_emergency_carrier_area.xml
• rebuild your custom ROM
• you are done
