how to crack unlock pattern lock of any android device0 Compatibility:

This guide (hack) works with any Android phone or tablet (running Gingerbread, ICS, Jelly Bean). It does NOT require rooted device. So, loosing warranty is not an issue.

Pre-requisites:

  • It is recommended to charge your device up to 60% battery level.
  • (Important!)USB debugging” option must be enabled in your device. Without this, you’ll NOT be able to crack the pattern lock.
  • Disable Antivirus or any security application installed in your PC.
  • In some cases, Root is required to make it work.
  • (Optional) If “USB Debugging” is disabled then you’ll have to install a Custom Recovery (like CWM) on your phone.

Procedure to Crack / Unlock Pattern Lock of your Android Device:

Update (20 Sep 2013): Please skip to method 3 if method 1 and method 2 don’t work for you. It’s a full proof method.

  • Download ADB & Fastboot Files from the link mentioned below:
  1. ADB & Fastboot files for Android
  • Extract ‘Fastboot.zip‘ (the one you’ve just downloaded) to any convenient location on your PC (may be Desktop).
  • After extracting the zip file, open Fastboot folder. You’ll find following 4 files inside it.
  1. adb.exe
  2. AdbWinApi.dll
  3. AdbWinUsbApi.dll
  4. fastboot.exe
  • Now connect your Android phone to the Computer.
  • On PC, in fastboot folder, hold shift button & right click on empty space (Check the image below).

  • Select “Open command window here” option.
  • In command prompt, type following command to ensure that if your device is properly connected or not.

adb devices

  • After entering above command, some random numbers will appear (Check the image given below). This confirms that your device is connected properly. Now there are two methods to crack unlock pattern. Choose one which is applicable on your device.

how to crack unlock pattern lock of any android device2

Method 1: (Applicable on Samsung Phones. May or may not work with other devices)

  • Now type following commands one by one (and hit enter after each command).

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’;
.quit

Method 2: (Applicable on non Samsung devices. May or may not work with Samsung Phones. You can try though):

  • If above commands don’t work then try with this one.

adb shell rm /data/system/gesture.key

  • After typing all these commands, restart your phone.
  • As soon as your device gets rebooted, you’ll see the pattern lock isn’t unlocked yet. Well don’t worry just enter any pattern & phone will get unlock automatically.

Method 3 (new):

  • It’s a quite simple method than the other two. By using this method you can crack / unlock both, pattern lock as well as pin / password lock. But before you use this method, your device must have a custom recovery like CWM installed on it. Note that you may also require to root your device just in case if it doesn’t work by having CWM only (it’s a far rare case though). It should work with CWM Recovery alone.
  • So, lets get started: firstly download a Lockscreen bypass file from the link given below:
  1. Pattern / Password Bypass for Android
  • Copy the downloaded zip file on your device’s internal / external memory by any means.
  • Now, boot into recovery mode on your phone / tab. Note that, each device has a different method (key combinations) to get into recovery mode. If you don’t know how to boot into recovery, you can Google it or ask us in comments below (include your device model along with the comment).
  • After getting into recovery, select install zip from sdcard followed by choose zip from sdcard. Navigate to the file you’ve just transferred on your phone. Hit Power button to select the file and confirm the installation by selecting ‘Yes – Install LockScreen_Security_bypass.zip’.
  • As soon as installation gets completed, select ‘reboot system now’ to restart the phone.
  • Once the phone gets rebooted, you’ll see that the pattern / password lock is still there. But don’t panic, just enter any pattern / password and it will get unlocked by itself.
