Smartphones and tablets from LG Electronics are known for their reliability, but over time, even the most stable systems can fail. Users often encounter situations where the device starts to work slowly, freezes, or refuses to accept correct commands. In such cases, the only correct solution is a complete return to the original state of the system, which allows you to eliminate software errors and clear the memory of digital garbage.
The reset procedure, or Hard Reset, completely deletes all user data, returning the gadget to its “out of the box” state. This may be required when selling the device, transferring it to another owner, or before flashing it. It is important to understand that after performing these steps, it will be impossible to restore deleted files without a preliminary backup, so you need to approach the process consciously.
In this guide, we will look at all the available methods for restoring factory settings on devices LG. We will analyze in detail standard methods through the menu, the use of engineering button combinations for locked phones, and advanced options for advanced users. Follow the instructions carefully to avoid losing important data.
Preparing the device for a full reset
Before taking drastic measures, you need to perform a number of preparatory steps. Backup This is the most important step that cannot be ignored. Make sure that all your contacts, photos, documents and messages are saved in cloud storage Google Drive or on external storage. During the reset process, the internal memory will be completely formatted.
The second critical point is battery charge. The system restore process can take anywhere from 10 to 30 minutes, and if the device shuts down in the middle, it can damage system files. Charge the battery to at least 60-70%to ensure sufficient energy reserves. It is also recommended to remove the memory card SD and SIMcard so as not to accidentally erase data from them or damage contacts.
Before starting the procedure, be sure to disable the “Find My Device” function in your Google Account if you remember the password. This will prevent activation from being blocked after a reboot.
Don't forget to write down or remember your Googleaccount details. After the reset, the system will require you to enter the login and password of the account that was previously synchronized with the phone. This is a security measure FRP (Factory Reset Protection) that protects the device from theft. Without this data, you will not be able to use your phone.

Resetting settings through the smartphone menu
The safest and easiest way to return LG to factory settings is to use the system’s built-in menu. This method is suitable for devices that turn on and respond to touches on the screen. The interface may differ slightly depending on the version Android and shell LG UX, but the logic of actions remains the same for all models.
First, open the “Settings” application. In the list of options, find the “General” section or go directly to the “System” tab. You are interested in the “Restore and reset” item (sometimes called “Backup and reset”). Here you need to select the “Reset settings” option.

After clicking the "Reset phone" or "Erase everything" button, the device will reboot and begin the cleaning process. The screen may turn off and on several times - this is normal behavior.
⚠️ Attention: If there are several user profiles installed on the device, a reset via the menu may only affect the current profile. To completely clear all profiles, use the method via Recovery.
Hard Reset via Recovery Mode (button combination)
If the smartphone does not turn on, is stuck on the logo, or you have forgotten the pattern key, the standard method will not work. In this case, recovery mode is used Recovery Mode. On devices LG entering this mode often requires a specific sequence of actions that differs from most other brands.
The classic method for many models LG looks like this: turn off the phone completely. Press and hold the Volume Down button and the Power button at the same time. As soon as the logo LGappears, release the Power button for a split second and immediately press it again while continuing to hold the Volume button. This action must be repeated several times until the reset menu appears.
Secret method for older models
On some older LG models (G2, G3 series), entering the reset mode is done by holding down the volume button and connecting the USB cable to the computer or charger. If the standard method does not work, try this option.
When the “Factory data reset” prompt appears on the screen, press the Volume button to confirm (Yes) or the Power button, depending on the model. The system will ask for confirmation again. After selecting “Yes”, the formatting process will begin. When completed, the phone will prompt you to reboot.

- 🔘 Use the button combination: Volume Down + Power.
- ⚡ Release and press the power button when the logo appears.
- ✅ Confirm the reset using the volume buttons.
Using LG UP and other PC utilities
For advanced users and in cases where the software failure is too serious, there are specialized tools for working with firmware via a computer. The official utility LG UP allows you not only to update, but also to completely reflash the device, which is analogous to a hard reset at a deep level. This method requires the presence of drivers and a firmware file (KDZ).
You can also use the command through debugging by ADB (Android Debug Bridge), if USB debugging was previously enabled on the phone. Having connected the phone to the PC, you need to enter the command adb reboot recoveryin the command line, which will put the device into recovery mode, from where you can wipe. However, if the phone is locked or does not turn on, this method will not work without preliminary configuration.
When working with programmers, it is important to take into account the processor model and region of the device. Incorrectly selected firmware can lead to “bricking” the gadget. Always check the compatibility of the file KDZ with your specific model, indicated on the sticker under the battery or in. system.
Using PC utilities is a last resort when other methods do not help. It requires technical knowledge and the risk of damaging the system if an error occurs.
Table of keyboard shortcuts for different LG models
Since the model range LG is extensive, button combinations may vary Below. a table that will help you navigate depending on the series of your device. Please note that on devices with Android 10 and higher, the methods may be unified.

If none of the combinations works, try holding down the volume button and connecting the USB cable to the computer. This method often works on budget series LG K i X, where the standard input to Recovery is blocked by the manufacturer for ordinary users.
Possible problems and their solution
After a reset, users often face the question: “Why does the phone require a password from the old account?” This is how protection works. mean that the system files were damaged even before the reset, or the process was interrupted. In such cases, only flashing it through the computer using the utility often helps. FRP (Factory Reset Protection). Google locks the device if it detects that the reset was not performed through the settings menu (where a password was required), but rather through a hardware method. This is protection against theft.
Another common problem is the “bootloop”, where the phone constantly turns off and on. This may mean that system files were damaged before the reset, or the process was interrupted. In such cases, the only thing that often helps is flashing it through a computer using the utility LG Flash Tool.
⚠️ Attention: Interfaces and menu item names may change with security updates. If you do not find an exact match of the names, look for synonyms or similar icons.
Sometimes after a reset the touchscreen may not work correctly or the calibration may be lost. In this case, recalibrating through the engineering menu (code ##6484## or analogues) or installing calibration applications from the Play Market will help if the phone is at least partially functioning.
