#2. Unlock Lock Pattern using Command Prompt

This is the second way and its confirmed by many online website's that it works great, so lets just hop into the tutorial on how it actually works.

  1. Connect your Android Device to your PC.
  2. Now open Command Prompt as an administrator.
  3. Now type below code into it and press enter.

    adb shell
    cd /data/data/com.android.providers.settings/databases
    sqlite3 settings.db
    update system set value=0 where name='lock_pattern_autolock';
    update system set value=0 where name='lockscreen.lockedoutpermanently';

  4. Now you will some screen like below and then you can reboot your OS and now when your device boots up again try unlocking your device using any lock pattern and it will work pretty fine.
  5. If you face any problem repeat same steps but instead of the above code try using adb shell rm /data/system/gesture.key and press enter and now try rebooting your device and see if it works.

#3. Unlock Lock Pattern using Hard Reset Option

So this is the third method and even developers this works like a charm too, well we will be using the inbuilt Android feature that's Hard reset (every phone has this feature) and this will delete all the user's data which will unlocks the device.

Note This method will remove everything from your device except stuff on your SD Card, so make sure you attempt it only if none above method works and you seriously need to unlock your device.

  1. Shut Down your Android Device.
  2. Now we need to hold few buttons combination in order to get our device booted in, well every phone can have different combination so normally its Volume UP + Power button so try that else use below from popular devices.
    • Nexus 7 - Volume Up + Volume Down + Power
    • Samsung Galaxy S3 - Volume Up + Home + Power
    • Motorola Droid X - Home + Power
    • Now these were the popular phones I know, but you have any other phone and above combination is not working then you can Google your phone combination keys and you will get something for sure :)
  3. So now as soon as you see your phone's logo you can release the Power but you should keep holding the Volume Button till you get into the Recovery Mode.
  4. Now you will see some screen like above just navigate to wipe data/factory reset using volume keys and then press Power button to activate it.
  5. Now you will get the Yes and No option (Google is creative in this isn't it) so slide down to that Yes -- delete all user data option and press that.
  6. Now it will wipe clean your device and will remove all the restrictions and now you can once again login to your OS. Well you can see below video tutorial too for easier access to your recovery mode.

So possibly these were the three methods I think that can be used to unlock your lock pattern on Android Device, well if you think you have some other easiest way then do comment below I will add that method too :)
