How to bypass the security pattern lock on your Android device

Trend

Having protection and security on your Android device is one essential thing you should take into consideration, especially if there are people who tend to snoop around your device without your permission. The possibility of actually forgetting the pattern you’ve set to unlock your device is not that high, but it may happen. What’s worse, your friend may have messed around with your Android device and set a completely different unlock pattern, leaving you stumped when you try to unlock your device.

In situations like that, you could lose all hope and start bickering with the perpetrator (either your friend or yourself), not realizing that there is a way to go around that misfortune. Thanks to XDA Developers member m.sabra, an easy way to regain access to your locked device has been made for your perusal.

In this guide, learn how to bypass the security pattern lock on your Android device.

Warning

  • The instructions in this guide reportedly work for both rooted and non-rooted devices.  Root privileges, however, make this guide work in most cases.  Several users have reported that the guide does not work in certain non-rooted devices.
  • The information in this guide is provided for instructional and educational purposes only. There is no guarantee that these instructions will work under your specific and unique circumstances.
  • Use these instructions at your own risk. We shall not hold any responsibility or liability for whatever happens to you or your device arising from your use of the info in this guide.
  • Read and understand the whole guide first before actually performing the instructions.

Requirements

  • Any Android device with USB Debugging enabled, preferably rooted; or, if not rooted, the device must be running a kernel that grants root access to the adb shell.
    • To enable USB Debugging on devices running Android 4.0 and up, go to Settings > Developer Options. Check the box beside the USB Debugging option.
    • For devices running on older versions of Android, go to Settings > Applications > Development. Check the box beside the USB Debugging option.
  • A computer with ADB installed
  • Your device’s USB cable
  • Make sure your device’s battery is charged 75% or more to avoid interruptions during the process.
  • Backup all personal data on your phone to make sure you have a copy of your personal data (e.g., contacts, SMS, MMS, Internet settings, Wi-Fi passwords, and the like) in case the procedure in this guide erases such data.

Instructions

  • Connect your device to your PC using the USB cable.
  • On your computer, open a terminal window (or command prompt on Windows-based machines).
  • Type in the following commands at the terminal or command prompt window. Press Enter after every line:
    • adb shell
      • The prompt should display a # rather than a $.  Otherwise, enter su to switch to the root user.
    • 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';
    • .quit
    • exit
    • adb reboot
  • After your device has rebooted, enter the following commands at the terminal:
    • adb shell
      • The prompt should display a # rather than a $.  Otherwise, enter su to switch to the root user.
    • rm /data/system/gesture.key
    • exit
    • adb reboot
  • Your device will reboot.  After it reboots and asks for a security pattern, you can use any pattern and the device will still unlock.
  • Once you regain access to your device, make sure to change the system security settings to re-select another unlock pattern.

    • Congratulations! You have successfully bypassed the pattern unlock on your device. You don’t need to panic anymore because you now know that there is a way back into your phone after you’ve been locked out.
