How to Bypass Android Lock Screen? [100% Working]

What is Android PIN ByPass?

Android PIN bypass refers to the process of bypassing the PIN code that is used to lock and secure an Android device. This can be done through various methods, including using third-party software, exploiting software vulnerabilities, and using physical methods.

One method of android PIN bypass is through the use of third-party software. There are various programs available online that can be used to bypass the PIN code on an Android device. These programs may require the user to connect their device to a computer and run the software, but they can be effective in unlocking a device. However, it is important to note that using third-party software to bypass the PIN code on an Android device may void the device's warranty and can also potentially damage the device.

Another method of android PIN bypass is through exploiting software vulnerabilities. This can be done by identifying and exploiting weaknesses in the Android operating system or in individual apps on the device. For example, a vulnerability in the lock screen app could be exploited to bypass the PIN code. However, this method can be difficult to accomplish and requires a certain level of technical expertise.

A physical method of Android PIN bypass is through the use of specialized tools. For example, a "jumper" tool can be used to short-circuit the device's power button and allow the user to access the device without entering a PIN code. This method is highly technical and may damage the device if not done properly.

In this guide, I will demonstrate how we can perform an android PIN bypass on an android penetration testing lab that we had learnt how to set up in an earlier guide.

 

Requirements

1. PC running on Linux.
2. Running android penetration testing lab.
3. Target device(The device is created within the Android pentesting lab).

It is important to note that bypassing the PIN code on an Android device can have serious consequences. It can void the device's warranty, and it can also potentially leave the device vulnerable to hacking and other forms of cyber attacks. Additionally, bypassing the PIN code on a device that does not belong to the user is illegal in many jurisdictions. We recommend you set up an android penetration testing lab to test the android PIN bypass.

 

Installing virtual device

The first step to performing an android PIN bypass is to set up a virtual target device in our virtual lab. To create the target device, we launch android studio, navigate to the android virtual device manager and install a virtual device we want to work with as explained in the guide to set up an android pentesting lab. After installation is complete, we can access and use the created virtual device. As shown in the image below, the device has no screen lock enabled.

 

Setting pin lock

After we are done with installing our target device, we can navigate to the security settings from where we will set the screen lock pin. We can try locking and unlocking the device after setting the PIN. As shown in the image below, the device now requires us to provide a PIN to unlock the phone.

 

Connecting to the target device via ADB

For us to perform an android PIN bypass, we need to connect to the target device via ADB. To view if our target device is connected via ADB we run the below command on the terminal.

adb devices

As shown in the image above, we can see a list of the connected devices. If we see the device is connected, we can now perform an android PIN bypass.

 

Android PIN bypass

Android PIN bypass requires us to acquire the target device shell which we will use to remove the PIN related files on the target device which we already locked in the previous step. We run the below command to acquire a shell on the target device via ADB.

adb shell

Once we have a session running, we can now navigate to the folder containing the PIN files which we are supposed to delete in order to successfully perform an android PIN bypass. Using the below command we navigate to /system folder.

cd /data/system

In this folder, we are looking for and deleting any files with the words “lock” and “key”.We can use the below command to remove the related files.

rm gesture.key

rm locksettings.db

rm locksettings.db-shm

rm locksettings.db-wal

rm password.key

We can now restart the target device to check if the android PIN bypass process has removed the PIN lock successfully. Once the device has restarted, we have our home page as shown in the image below. No PIN is required to unlock the device. We have successfully performed an android PIN bypass.

 

Conclusion

In conclusion, Android PIN bypass refers to the process of bypassing the PIN code on an Android device. There are various methods of doing this, including using third-party software, exploiting software vulnerabilities, and using physical methods. However, it is important to note that bypassing the PIN code can have serious consequences and should only be done as a last resort. It is always recommended to use legal and safe methods to unlock your phone or consult the phone manufacturer for help.
