Forgot security lock pattern on Jelly Bean device with Wifi and 3G data turned off

I forgot my security lock pattern and my Wifi and 3G connections are switched off. I can hard reset the phone (Galaxy Nexus) from recovery mode, but that would wipe all my data. ADB is also turned off so I cannot recover my data unless there is a way to turn on ADB while the phone is locked. I understand that ClockWorkMod recovery turns ADB on automatically when it is installed.

• Do I need to root the phone to install ClockWorkMod?


• If yes, can I root the phone while it is locked?


• Is there any other way to recover the data from the phone before I reset it?

Since the FBI cannot bypass the screen lock, I guess you will not. Check out http://wired.com/threatlevel/2012/03/fbi-android-phone-lock
