If you have root access and TWRP on your device it's quite simple:

  • You have to boot up into TWRP than start the (TWRP's) built-in file manager, navigate to /data/system and delete password.key and/or gesture.key and reboot.

If you have root access but TWRP not installed and you can access to FastBoot mode you can boot up into TWRP recovery with this:

  • fastboot boot twrprecovery.img

But it is just a temporary method.

Or if your device isn't rooted or there is no way to install TWRP on it, you have to hard reset (HR) your phone from the original recovery mode* or if you have an active internet access on your device and you activated ADM (Android Device Manager) you can add a new password to your lockscreen:

  1. On a computer or other mobile phone, visit: google.com/android/devicemanager
  2. Sign in using your Google login details that you also used on your locked phone.
  3. In the ADM interface, select the device you need to unlock (if it isn’t already selected).
  4. Select ‘Lock’
  5. In the appearing window, enter a temporary password. You don’t have to enter a recovery message. Now click ‘Lock’ again.
  6. If it was successful, you should see a confirmation below the box with the buttons Ring, Lock and Erase.
  7. On your phone you should now see a password field in which you should enter the temporary password. This should unlock your phone.
  8. Now, before you go on with your life, go to your phone’s lock screen settings and disable the temporary password.

*: If you do this all of your data will be purged, of course security reasons. So it must be your decision.

Have you tried a hard reset? If not, I would recommend trying that via the recovery. If you cannot, try using adb to reset it.

  • I think he can't even boot into recovery mode to do a HR. But if his phone is rooted there's another way too.
