Reset lockscreen pattern, forgot original

Is there a way to reset the lockscreen pattern if you have forgotten the original pattern? I'm currently using fingerprint to unlock so it's not an issue to get into the device, but I just realize that if my finger print scanner should stop working for whatever reason then I'd be locked out. I normally used a set pattern but I remember I had some issues after I installed the CM rom so I did a factory reset and reinstalled stock ROM but now the pattern I have been using for years is not being recognized and I have no idea what pattern is stored now. Of course trying to reset the pattern requires the current pattern. Is there any way around this?

    If you are rooted, you can use a root capable file explorer to navigate to /data/system.

    From there, you can delete the files "gatekeeper.pattern.key" and "locksettings.db" and then reboot.

    That should do the trick and allow you to set up your lockscreen security afresh. That said, you do so at your own risk and detriment.

    Please do a backup beforehand.

    I may be wrong but...I think the only way is with a factory reset...yuk

    and make sure you know the google account that was on the phone before the reset because resetting a locked device triggers the kill switch and the only way back in is using the Google account that was in use on the phone before the reset.

    You could try Android Device Manager.

    Find, lock, or erase your lost phone or computer - Accounts Help

    Login and set a new lock password.

    Best of luck.

    This hasn't worked since Android Lollipop.

    To clarify a little, device manager apparently doesnt allow you to change the lock screen anymore if there is already one active, it simply says that one is already active and so the new one is not needed.. You are still able to lock the device remotely but it simply activates your current lock screen settings

    When a number of malicious apps began to abuse that function, google patched it so that some of the ransomware at the time could not lock the device by setting a new pin.

    While it means less ability to bypass the lockscreen when you forget the pin, it is better than leaving a security vulnerability in place.

    Glad to hear it.

    On this phone, it is a known issue with doing nandroid backups and restores with screen security enabled. Sometimes the password/pattern/etc gets corrupted so that your existing password/pattern/etc no longer works. Luckily, it is easy to fix.

  • I have a similar problem, but I was using a password instead of a pattern.  Is there a similar solution?

    Also, I'm not rooted, what's the easiest way to do that?

    Thanks in advance.
