The situation when you forgot the pattern key on your smartphone Dexpcan unsettle any user. The mobile device becomes inaccessible, blocking access to contacts, photos and important applications. This is a common problem that owners of Android gadgets face, especially if a lot of time has passed since the last password change.
Fortunately, in most cases, restoring access is possible without contacting a service center. There are several proven methods for bypassing the screen lock, ranging from using Google account to a complete reset. The choice of a specific method depends on the version of the operating system Android, your model Dexp and the availability of preliminary security settings.
In this article we will analyze in detail all the current methods for solving the problem. We will consider both soft ways to save data and radical measures necessary in difficult cases. It is important to act consistently and carefully so as not to aggravate the situation and not to lose valuable information forever.
Using the "Forgot the key" function via Google
The easiest and safest way to unlock the device is available if the smartphone is connected to the Internet and linked to an account Google. After five unsuccessful attempts to enter a pattern key, the message “Forgot your key?” usually appears on the lock screen. or “Forgot your pattern key?” Clicking on this button puts the system into access recovery mode.
You will need to enter the login and password for Google accountthat was previously synchronized with the phone Dexp. The system will check the data in the cloud and, if verified successfully, will offer to set a new screen lock method or disable it completely. This method works without loss of personal data, which makes it a priority.
However, it is worth considering that in new versions Android (starting from 5.0 and higher) this function has been removed for security reasons. If you have a modern model Dexp with the latest firmware, this option may not be available. In this case, the system simply will not respond to entering incorrect data or will not show the recovery button.
⚠️ Attention: For this method to work, the phone must be connected to a Wi-Fi network or mobile data. If the device is locked and the network is disabled, try calling the quick settings menu from top to bottom (if possible) or reboot the device so that it automatically picks up a known network.
If you do not remember the password for your Google account, restore it in advance through a computer or other device at accounts.google.com before trying to unlock the phone.
Reset settings through the menu Recovery
If soft methods do not work, you will have to resort to a hard reset, known as Hard Reset. This procedure completely clears the internal memory of the smartphone Dexp, deleting all user data, including photos, contacts and installed applications. The device returns to its factory state, as it was immediately after purchase.
To enter recovery mode, you must perform a certain key combination with the device turned off. Most often for smartphones Dexp you use the volume up button and the power button pressed at the same time. Hold them until the brand logo or menu appears Recovery.
Navigation in the menu Recovery is carried out using the volume buttons (up and down), and selecting an item using the power button. You need to find the section Wipe data/factory reset. Confirm the action by selecting Yes -- delete all user data. The process will take a few seconds, after which you should select Reboot system now.
☑️ Preparing to reset via Recovery
⚠️ Attention: After resetting the settings on modern devices, protection will work FRP (Factory Reset Protection). When you boot for the first time, the phone will require you to enter the login and password for the Google account that was synchronized with the device before it was blocked. Without this data, the phone will be impossible to use.
The recovery menu interface may differ depending on the version. Android. On some older models Dexp the menu may be blue with text commands, on new ones it may be graphic with a black background and orange or blue highlights. The principle of action remains the same: search for the reset point and confirm.
Deleting a key file through a file manager
This method is suitable for advanced users and works only on older versions Android (up to 5.0), and also requires root access an installed file manager with access to system folders. The essence of the method is to delete the file in which the hash of the graphic key is stored.
The file responsible for blocking is usually called gesture.key or password.key and is located along the path /data/system/. If you have access to this directory through a file manager (for example Root Explorer or ES Explorer with superuser rights), you can simply delete this file.
/data/system/gesture.keyAfter deleting the file and rebooting the device, any entered pattern will be accepted by the system, or the lock will disappear at all. This allows you to keep all data on your phone Dexp intact. However, on modern devices with disk encryption, this method is ineffective without full decryption, which is impossible without the old key.
Alternate path for the PIN code
If you have forgotten the digital PIN code instead of the pattern key, look for the password.key file in the same /data/system/ directory. The principle of deletion is similar.
Unlocking through the Find My Device service
Google provides an official tool for remote control of devices under control Android. The service Find My Device (Find Device) allows you not only to track the location of a lost phone, but also to remotely erase data from it, which automatically removes the screen lock.
To use this method, you will need a computer or other smartphone with Internet access. Go to the official page of the service, log in to your Google account and select a blocked device from the list Dexp. In the action menu, select the "Wipe device" option.
The command will be sent to the phone as soon as it connects to the network. The process is similar to reset via Recovery: all data will be deleted, but you will receive an unlocked device. This is a great option if the buttons on the phone itself do not work or you cannot enter the recovery menu.
| Method | Saving data | Internet required | Difficulty |
|---|---|---|---|
| Google "Forgot" key" | Yes | Yes | Low |
| Hard Reset (Recovery) | No | No | Medium |
| Find My Device | No | Yes | Low |
| Removing gesture.key | Yes | No | High |
The Find My Device service only works if the geolocation and remote control function was previously enabled on the phone in the Google settings.
Using the ADB utility to unlock it
Tool ADB (Android Debug Bridge) is part of the Android SDK and allows you to control the device from a computer via a USB cable. This method may work if the phone Dexp has previously enabled USB debugging in the menu For developers.
Connect the smartphone to the computer, install the drivers and open the command line in the folder with the ADB utility. Enter the command to access the device shell: adb shell. If the connection is successful, you can run the command to delete the key file without superuser rights on some versions of the system.
adb shell rm /data/system/gesture.keyAfter running the command, reboot the device. If the method works, the lock screen will disappear. It is worth noting that on modern versions Android this vulnerability is closed, and the command may not perform the action without rooting the device. However, it's worth a try, as this is the only chance to save the data without resetting.
⚠️ Warning: Interface and debugging capabilities may vary depending on the shell installed on your Dexp. If the command returns the error "Permission denied", then you do not have sufficient rights to perform the operation.
Prevention and setting up alternative methods
To avoid similar situations in the future, it is recommended to set up alternative unlock methods. Modern smartphones Dexp support biometric identification: unlocking by fingerprint or facial recognition. These methods are not only more convenient, but also more reliable, since biometric data cannot be “forgotten.”
It is also useful to write down complex passwords in a safe place, for example, in a password manager or a paper notepad stored in a safe. Regularly backing up your data to the cloud Google Drive ensures that even in the event of a forced reset, you will not lose important information.
Check the smart lock settings (Smart Lock). This feature allows you to keep your phone unlocked in certain situations: when it is at home (geofencing), connected to a trusted Bluetooth device (such as headphones or watches), or when you are holding it in your hands. This greatly simplifies everyday use.
Set up Smart Lock in advance: go to Settings → Security → Smart Lock. Add trusted places or devices so that the phone remains accessible in familiar conditions without entering a key.
Frequently asked questions (FAQ)
What should I do if the phone asks for a Google account after resetting, but I don’t remember it?
This is FRP protection. You need to restore access to your account via your computer on the Google website. If recovery is not possible, you will need to flash the device at a service center using a specialized box to bypass FRP.
Will resetting the settings delete files on the SD memory card?
Usually, a standard reset via the Recovery menu does not affect the external SD memory card. However, it is recommended to remove the card before the procedure for greater security, since some reset options may suggest formatting the entire storage.
Is it possible to unlock Dexp without losing data on Android 10 and higher?
Unfortunately, on modern versions of Android with disk encryption enabled, it is almost impossible to unlock the device without losing data if the method through a Google account does not work. Encryption binds the decryption key to the user's graphic key.
Why does the combination of buttons to enter Recovery not work?
You may be holding the buttons down long enough or pressing them in the wrong sequence. Try connecting your phone to the charger and try again. Some Dexp models require you to press the power button, and then, without releasing it, add a volume button.
Will calling a locked phone work to unlock it?
On older versions of Android (before 4.4), during an incoming call, you could minimize the call screen and access the desktop. On modern devices Dexp this method does not work due to changes in the system security architecture.
