LG annually releases smartphones of excellent quality and equipment, which are a pleasure to use. But no matter how hard the developers try, it is impossible to prevent situations in which the phone requires a full factory reset.
To get the system in its original form, the developers have provided three methods for a general reset. The first option is considered the simplest, since its implementation requires several clicks in the firmware interface.
Option 1: from the menu
You can get the original state of the gadget by performing a number of simple actions:
- Save all the necessary user files and other information in a backup copy, on a memory card, in the cloud, or on your computer. Making a backup is very important, since after resetting all data from the smartphone will be deleted. You can read about how to reserve data in. It is suitable for all LG Android phones.
- Go to the standard settings menu.

- Confirm your decision by selecting the “Reset phone settings” button.
Option 2: Hard Reset
Is it possible to reset an LG phone to factory settings if you can't login? Yes, and in this case it will be called Hard Reset, since it is performed using physical buttons. To implement it you need:
- Turn off the smartphone with the power button or by removing the battery (if it is removable).
- Simultaneously hold down the power and volume down buttons until the screen with the LG logo appears, then release for 1-2 seconds and hold down again. On models with a physical Home button, you need to additionally hold it, as shown in the figure below.
The appearance of a black screen with a small menu in English will indicate that Recovery mode is enabled. Use the volume buttons to find the line “Wipe Data/Factory Reset” and select it with the power button. Now you need to confirm the action you are performing by clicking “Yes”.
After some time, the data will be reset and the smartphone will return to the initial Recovery screen. Selecting “Reboot System Now” will complete the procedure.

An additional way to return to the original state for models from LG G3 and older is to use a quick reset. It is performed in a few simple steps:
- Turn off the phone by long pressing the power button.
- Press and hold two keys at once: volume down and power on.
- After the LG logo appears, you need to release and immediately hold the power button again.

How to do a hard reset on LG E975 Optimus G (Black) from the settings menu?
Attention! Due to FRP (Factory Reset Protection, that is, reset protection), Android will ask you to enter the login and password of the account that was assigned before the Hard Reset procedure. Therefore, if you plan to sell your smartphone, you need to log out of your Google account (Settings - Accounts - Google - Delete account) before resetting, so that the person who receives your phone can activate their profile on it.
Given the wide range of Android phones and the difficulty of describing the reset process for a specific model, we will show the guide using the example of three fundamentally different devices and firmwares:
- Mi A1 on pure Android, which is also used in Nokia, Motorola, OnePlus (has a slightly redesigned system) and in all devices released under the Android One program;
- Galaxy S7, which runs Samsung Experience. Let us remind you that the Korean corporation is the largest smartphone manufacturer in the world, so it makes sense to show this shell;
- Redmi Note 5 on MIUI. The products of this company are in great demand in the CIS, so we could not ignore it.
The easiest way to perform a Hard Reset is through a special menu in the system parameters. Once again, we note that the location and name of the items may differ slightly depending on the phone used. The main thing is to find the main category for recovery and reset.
Xiaomi Mi A1 (pure Android 8.1 Oreo)
The device will reboot and you will have to go through the initial setup again as if it were a new phone.
Samsung Galaxy S7 (Samsung Experience shell)
Your phone will restart. All that remains is to configure it as after purchase.
Redmi Note 5 (MIUI firmware)
Attention! As you can see, the main thing is to find the “Reset” section. To ensure that you don’t get lost in all the parameters in search of the desired menu, it’s easier to enter the query “Reset” on the main page in the search box. Select the menu you are looking for from the list provided and you will be taken straight to it. And then everything is as in the instructions.

In this manual, we will tell you how to reset settings on LG. There are several ways to solve this issue, and all of them are essentially universal and valid for almost all models of the company’s mobile devices. Let us immediately note that Hard Reset on LG will erase all data from the smartphone, except for files located on the memory card, so copy all important files to your computer in advance.
Method one - settings menu
When asked how to format an LG, the first thing that comes to mind is to perform a reset through the settings. On your mobile device, go to Settings (List view) – Backup and reset – Reset settings. In the menu that opens, you can view information about what will be deleted. After reading, click the “Reset phone settings” button. Below are pictures with the same manipulations, but with the menu installed in the “Tabs” view.
Method two - through the service menu on LG
In this method, you will get a little acquainted with the service menu of your smartphone. It is worth noting that the entered code, which is presented below, is universal for mobile devices from LG, however, there are also special entered characters for each model separately. Open the dialer and enter 3845#*model number#. Instead of the model number, you need to enter the number of your device. For example, let's take the LG G2 D802 and in this case we dial 3845#*802#, after which the service menu will appear instantly. There is no need to press the call key. Next, scroll to the bottom of the menu and click “Factory Reset”. A confirmation request will appear and press the button again.
Method three - Hard Reset on LG
This solution is more suitable for the case where the above methods cannot be applied because the smartphone is frozen or does not turn on to get to the menu. Press the power button trying to turn on the device, then press the “Volume Down” key and the “Power” button. Within a few seconds, the LG logo will appear, and at this time you only need to release the “Power” button and press it again. After this, a menu should appear as in the image below. By pressing the volume rocker you make a choice on the question asked by the system, and by pressing the “Power” key you confirm your choice. Select the “Yes” item and wait for the operation to complete. Afterwards, the smartphone reboots – the LG hard reset has been completed successfully.
Method four – Recovery Mode
As in the third method, you need to manipulate the physical buttons of the device, but this time a little differently. When the smartphone is turned off, press the “Volume Down” and “Power” buttons, and as soon as the logo appears, release them and press them again. In some models, a combination of the “Volume Up” key and the “Power” button is possible. Ultimately, an image should appear on the screen, as in the picture or similar. Use the volume rocker to move down to the words “wipe data/factory reset” and press the “Power” button. Select “Yes”.
