I have an Android phone with password, but I don't remember it. I have access to the phone through Android Device Manager. I tried to change the password with it, but when I set the new password, Android Device Manager says:

The phone has a password, the password you just entered will not be used

How can I change the password? I have not logged in with Samsung and adb does not recognize the device.


I solved the issue by installing ClockworkMod, and Aroma file manager with a sdcard, then I removed the next files:

  • password.keypattern.key
  • locksettings.db
  • locksettings.db-shm
  • locksettings.db-wal
