Unlock Pattern lock of any Android phone. If you own an Android Smartphone then you must be well aware of the security related stuff available in your phone system.
Moreover, there are various types of lock screens provided to protect and secure your phone’s data from unauthorized access. Among all the different ways to password protect your phone, the most popular one which comes with every Android device is the Pattern, Pin or Password Lock.
But what if you forget the pattern lock or the password lock? Then you’ll have to log into your Google account which you’ve already set in. Besides, if even this method doesn’t work then there is no other option than wiping or factory resetting your phone.
This will wipe out your entire phone data along with the pattern or the password lock which you’ve set. Besides, This method is not effective as it wipes your phone data completely.
Hence, to overcome this, I am unveiling some of the major methods by which any user can bypass, unlock or crack the Pattern, Pin, or Password Lock of any Android Smartphone.
Moreover, this article is particularly for those Android users who have forgotten their Android Pattern, Pin, Face, or Password Lock and want to reset that without factory resetting, wiping, or using their Google account.

- Make sure your device has at least 60% battery level.
- Enable USB debugging mode in your phone settings.
- Temporary disable all the security-related applications on your PC.
Method 1: Regain your Original Pattern Lock back (Without Data loss)
Pattern lock is a set of gestures that an Android user performs to unlock his/her Smartphone. It seems to be complicated, but actually, it is not. It can be entered by the user joining points on a 3×3 matrix. Since Android 2.3.3 this pattern must involve a minimum of 4 points (on older Android versions the minimum was 3 points) and each point can only be used once. Moreover, the pattern circles can be numbered starting from 1 to 9 from the upper top-left corner to the bottom right corner as shown in the figure.
For example, if we select a number 7415369, then the pattern would look like:
Furthermore, this pattern is encrypted with a SHA1 hashing algorithm. So the SHA-1 hash for 7415369 will be “F56A6DF0A85F5B0EB1E661B5836ED423542AFA86”. This SHA-1 hash is placed in a file called gesture. key which is stored at a location /data/system folder in Android’s internal memory.
When a user sets the pattern lock, the phone automatically hashes the lock code with SHA-1 and saves the result into the file. While unlocking, when the user enters pattern lock, the phone compares its SHA-1 hash with the stored one and decides whether to give access or not.
Unlike patterns, Password Lock can contain characters, numbers, or special marks such as $, #, @ etc. Because of such complexion, the SHA-1 hash file number grows tremendously.
- Download and extract the adb.zip file on your PC. After extracting you’ll find the following files in it:
- Now connect your phone to PC using the USB cable.
- Open the ADB folder which you’ve just downloaded. Now press and hold the shift button + right mouse key simultaneously on a space in that folder. Refer the image:
- Select the ‘Open command window here’ option.
- As soon as you click on it, a black colored command prompt window will appear.
- In this command prompt window, type the following command to make sure that your device is properly connected to the PC or not.
- After entering this command, some random numbers will appear. This will confirm that your phone has connected properly.
- Now we have to copy the gesture.key file from /data/system folder located in Android’s internal memory to your PC. For doing so, we need to use the command ‘ADB pull’. So type the following command in the command prompt and press enter.
adb pull /data/system/gesture.key gesture.key
- This command will pull out the gesture.key file located in /data/system/ folder to the ADB folder.
- As that you have the gesture.key file, you can close the command prompt window. You can open the file using any text or hexadecimal editor. Here we use the File View Pro software. So download and install this software from the link provided above.
- Launch the File View software and open this gesture.key file in it. You’ll see something like this:
- The code ‘F56A6DF0A85F5B0EB1E661B5836ED423542AFA86’ is important here.
- Now download and extract the Android OS gesture.key dictionary on your PC.
- Open that dictionary and search this ‘F56A6DF0A85F5B0EB1E661B5836ED423542AFA86’ code in it. You’ll see something like this:
- Besides, smartphone encrypts the pattern of 1234 not as a string ‘1234’, but as a sequence of bytes 0×01 0×02 0×03 0×04. In other words we have a 0×01 for the first point and 0×09 for the last one. Then Android uses SHA-1 and places it in a gesture.key file. Here the gesture.key file contains 0xF5 0x6A 0x6D 0xF0 0xA8 0x5F 0x5B 0x0E 0xB1 0xE6 0x61 0x83 0x6E 0xD4 0x23 0x54 0x2A 0xFA 0x86 bytes value.
- Additionally, using the dictionary we can find out that it corresponds to 0×06 0×03 0×00 0×04 0×02 0×05 0×08 values, which means that we have a ‘7415369’ pattern.
- Try this pattern on your device and yes it will be successfully unlocked.
- You can use the same method in case of password lock. This is the most simplest and effective method of all. But remember that your device must be rooted.
- This is the most simplest and effective method to unlock your forgotten pattern/password lock of any Android phone.
Method 2: Reset the Pattern lock using ADB Commands
- Download and extract the ADB.zip file on PC.
- Now open the Command prompt window and type command ‘ADB devices’ to check whether your device is properly connected to PC or not. (Refer Steps 1 to 5 of method 1)
- Now type the following commands one by one. Don’t forget to 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
- If the above commands don’t work then try with this one.
adb shell rm /data/system/gesture.key
- Now you need to reboot your phone.
- After restarting, you’ll see that the pattern or password lock is still there. Don’t panic, just enter any random pattern or password and your phone will get unlocked.
Method 3: Flashing zip file from CWM recovery
For this method, your phone must have a custom recovery like Clockworkmod (CWM) installed in it.
- Download and copy the zip file on your phone’s external memory. You may use a memory card reader for that.
- Switch off your phone completely until it vibrates. You need to boot into CWM recovery mode now. Note that every device requires different key combinations to enter recovery mode.

Method 4: Using Aroma File Manager
This method does not require USB debugging as well as root access.
- Download and copy the Aroma File manager.zip file to your memory card. Remember not to extract it.
- Now switch off your phone completely until it vibrates. Boot the phone into recovery mode. Different phones have different ways to enter recovery mode. If you don’t know how to boot into recovery, you can Google it or you can also ask us in the comments below.

- In stock recovery, there is no option to mount partitions, so navigate to the apply update from sd card option and select it. Now navigate to the Aroma File Manager zip file and flash it.
- In Aroma File Manager, click on the menu option and then go to settings and select Mount All Partitions. Now, exit from Aroma File Manager and re-flash it.
- (For both Stock/ CWM recovery) In Aroma file manager, navigate to the /data/system folder.
- Note: If you have sd-ext mod to increase internal storage, go to /sd-ext/system/
- In /data/system/ folder delete the following files if they exist:
gesture.key (for pattern lock)
password.key (for password lock)
- After deleting, exit the Aroma file manager and restart your phone.
- If the pattern/password lock still exist then don’t panic just try any random pattern/password and the phone will get unlocked.
