Description

This module removes the screen lock data files to remove the unlock mechanism. If the device still has a lock, the password will be blank.

The file which are removed:

  • /data/system/password.key

  • /data/system/gesture.key

Verification Steps

  1. Start msfconsole

  2. Get shell or root access on an Android device

  3. Do: use post/android/manage/remove_lock_root

  4. Do: set session [session]

  5. Do: run

  6. You should be able to unlock the device without a password or gesture.
