How to factory reset "Android Lenovo"?
Lenovo devices, like other Android devices, also have a factory reset option that allows users to delete any personal files, user settings and apps, and return the device to its out-of-box state. This question is asked by many users, since the Lenovo interface has a rather specific look, and the settings in it can be seriously different.
If your mobile phone or tablet from this brand becomes very slow, it regularly crashes, you want to get rid of a virus, or your mobile OS refuses to work, you can reset the device and restore it to its original state.
Since resetting will erase your personal files and documents from your Lenovo device, we strongly recommend that you back up any important data to an external drive or computer. How to reset "Android" to factory settings on such a device?
When the gadget can be turned on
If you can turn on your Lenovo phone or tablet and log into it, you can simply reboot it through Settings by selecting the appropriate menu bar. In the "Personal data" section, find and tap "Factory settings" to start erasing all data on your phone or tablet. Click on the "Reset" button located at the bottom of the list. You may receive another message: “Do you want to delete all your personal information and downloaded applications? You cannot undo this action! " Click the Erase All button to restore your Lenovo device to factory settings.
You will delete all information from the gadget's internal storage, including:
- your Google account;
- system and application data and settings;
- downloaded applications;
- music;
- a photo;
- other user data.
How to reset a failed Lenovo device?
As noted above, there is another way to reset Android phones or tablets by pressing the hardware buttons. It is known as a hard reset. Sometimes your system can crash so seriously that you cannot turn on the gadget and enter the menu. How to reset "Android" to factory settings in this case?
In that case, you can do a hard reset on your Lenovo phone and return it to its original factory settings. To hard reset a Lenovo device, you need to turn off your phone, wait a couple of minutes, and then press the Power and Volume keys at the same time and hold them until you enter recovery mode. While in it, use the volume up and down buttons to move up or down and select items in the list, then press the power button to confirm the selected item.
In Lenovo recovery mode, select "Erase data / factory reset" and confirm your choice, then select "Erase cache partition". After that, scroll up the menu and select "Reboot system now" and confirm the choice. After these steps, your phone or tablet will be restarted.
In addition, this method of how to reset "Android" to factory settings also works in cases where you cannot remember the password or pattern to unlock the screen. You can remove them using this process.
Like any other operating system, Android may not always work the way you would like it to. For example, when you launch the simplest application, the smartphone starts to slow down or freeze. Often, something similar happens even with a regular incoming call. Many owners of Android smartphones and tablets are upset, and some even offer to buy a new device. Do not hurry! Most problems can be dealt with with a factory reset. This function is present in this operating system.
In English, the function is called Hard Reset, which can be translated as "hard reset". In fact, a system reboot occurs, which restores the original factory settings. In addition, all information that was added by the user is deleted, including applications, SMS messages, contacts, video and audio clips, etc. Therefore, before a hard reboot, it is recommended that you save the data that you will need later.
Information is deleted only from the phone memory. The files that are on the memory card, if present, will not be deleted. However, you can remove them yourself from the menu using a software reset.
So, if you decided to make a Hard Reset and saved all the important data that you needed (for example, using a backup), then we can proceed to the procedure itself.
Method one
I will show an example on a "naked" basis. If you are using a smartphone or tablet with add-ons, it is possible that the menu will change slightly, although the procedure itself will not change. Go.
We are looking for the "Settings" application on the desktop. If it is missing, find it in the "List of Applications". I have "Settings" on the main screen.
The menu has opened. Now you need to find the "Recovery and reset" section.
We go in and select the section "Return to factory settings" - "Reset settings". Here you can also configure the backup of your data.
A kind of memo will open in front of you, where it is written that all data will be deleted from the device's internal memory, including settings, applications, and even the added Google account (the account itself, of course, will not be deleted, just next time you will have to re-enter your login and password from him). Click on the "Reset phone settings" button. If you also need to clear the memory card, check the box next to the "Clear memory card" item.
The system asks again whether to reset? If you are ready, click "Erase All". The device will reboot. Most likely, the reboot will take a little longer than your gadget normally boots - this is quite normal, do not panic.
Method two
You can try an even simpler method. All you need to do is dial * 2767 * 3855 # and send a call. After that, Hard Reset will automatically occur.
However, I do not recommend using this method for the simple reason that, according to reviews, this set of numbers can perform different functions on different devices. So, on some devices, it supposedly changes IMEI. How true this is, I find it difficult to say, and therefore I advise you to be as careful as possible.
Method three
This is called a hard reset. You should only use it if your device does not turn on. If it works, use the first method.
So, your device does not turn on, just in case we take out the memory card from it, if there is one. To enter the Android system recovery (the menu with which we have to work), you need to hold down the buttons on the device in a certain order. The problem is that the combination of buttons may vary from manufacturer to manufacturer. I decided to show you an example on a device from Samsung, one of the leaders in the Russian market of mobile devices.
Since the device is already turned off and does not turn on, we immediately proceed to active actions.
- Hold down the volume up key, power button and home button.
- Keep them pressed until a green robot appears or the menu starts loading.
- Using the volume keys, select wipe data / factory reset and confirm it with the on / off button of the device.
- In the menu that opens, select the Yes - delete all user data item, after which the reset and deletion of settings and files will begin.
- Then click select Reboot now and the device will reboot. You will receive a device with a completely clean operating system.
About restoring settings
After the user makes a Hard Reset, he will probably want to use the backup to return all his settings, files and applications. Should I do it? The issue is controversial.
The problem is this: if your device was not working properly, for example, freezing or slowing down during operation, then it is quite possible that the cause was some kind of application or certain settings. If you restore the backup, then there is a high probability that your device will work exactly the same as before the full reset. Therefore, it makes sense to restore the backup only if you are sure that the problem is definitely not in the previous settings or applications.
Contacts can be transferred manually, as well as the necessary documents, and applications can be downloaded from. In my opinion, this is the most optimal solution.
Custom firmware
As for custom firmwares, they are restored in exactly the same way, there is no need to reinvent the wheel. Most importantly, remember that if you need to hand over the phone under warranty, you will first need to bring it to life if it does not turn on (use the third method), and then upgrade to the factory firmware. And remove root-rights, if they were installed.
Over time, even with ideal use, the device starts to load more and more with different programs. It is for this reason that the performance of the device drops after several months of use. In this case, you need to reset Android to factory settings. After that, all data in the phone's memory will be deleted, and the memory card will not be touched.
If you have such a need, then we recommend using our instructions on how to reset the settings on Android to factory settings. Let's consider how best to do this and what you need to do first before resetting the device.
Android users know different factory reset methods, but not all are safe. For example, if you decide to do a full reset through the Recavery menu, since you are preparing the phone for sale, then you should know about the new feature from Google. Namely, starting with Android 5.0 Lollipop, the company began to implement Factory Reset Protection as an additional security tool.
The essence of which is that after a factory reset, even through the Recavery menu, the device remains linked to a Google account. The next time you set up the device, you will have to enter the account information that was on the device. And so that you do not have to look for how to bypass Google after resetting the settings, it is better to immediately delete the user account and completely unlink the device from the Google account.
Therefore, before resetting the settings via the Recovery menu, be sure to delete your Google account if you are going to sell the device.
When you factory reset a phone with FRP enabled and try to set it up as a new device, you will be prompted for the username and password of the last Google account that was registered with the device. If you do not have this data, the phone will remain locked and you will not be able to access it.
How to disable FRP:
- This step will differ slightly depending on your phone model. IN Samsung Galaxy open up Settings\u003e Lock screen & security> Screen lock type and select No. On Google pixel open up Settings > Personal > Safety > Screen lock and select No.
- The next thing you need to do is delete your Google account.IN Samsung Galaxy open up Settings > Cloud and accounts\u003e Accounts and select Google, then click the three vertical dots in the upper right corner, or Extras\u003e Delete your account. On Google Pixel, go to Settings > Accounts and sync\u003e google and tap the three vertical dots in the upper right corner, then tap Delete your account.
- If you are using a Samsung phone, you also need to delete your Samsung account, similar to the previous method.
Data encryption on Android
When you perform a factory reset, the device deletes the addresses of all your data. Therefore, the phone does not know where the data is stored. But since the data was not physically overwritten by others, it is possible to use recovery software and get some of it back.
Therefore, if you have a default phone with Android 6.0 Marshmallow operating system installed, then the device data is encrypted by default. If it is lower, then it is possible to encrypt the data yourself. But before that, it's worth charging the device's battery.
Reset settings via Recovery
How to enter the Recovery menu can be seen below, but remember that this method is different on different devices. To move in the Recover menu, use the volume keys and the power button of the device.
1. Turn off the device and use one of the following methods:
- Have volume down + Turn on the device (HTC, LG, Sony, Huawei, Motorola, Fly, Asus).
- Volume up + Power on device (HTC, Samsung, Meizu, Xiaomi, Sony, Huawei, Fly, Asus).
- Power on device + Home key + Volume up (Samsung).
- Volume up + Volume down »+ Turn on the device (Sony).
2. Select an item wipe data / factory reset and Yes - delete all user data.
3. The last step is to select the Recovery menu item reboot system now... After restarting the device, you will receive the phone in the state it was in after purchase.
On Meizu and Xiaomi devices, the Stock Recovery menu may differ. Since it will not only be in Chinese, but will also have new interface items.
How to reset to factory settings
Easier is to reset the device from the settings menu. The essence of which is that this method will delete all data, including files and downloaded applications. In this case, the Google account will be deleted as well.
On most Android phones, open Settings\u003e Backup & reset\u003e Factory data resetand then press Reset phone or Reset device.
On Samsung Galaxy devices, go to Settings\u003e General settings\u003e Reset\u003e Factory data resetand then press Reset device.
How to reset Android to factory settings with a code

Try them in dialing mode. You may have to press the call key. After the device restarts, the factory reset process will begin.

Hard Reset, aka Hard Reset, is done in two main ways. Regardless of the method you choose, take care of backing up your personal information, and also remove the memory card from the tablet and, just in case, the SIM card, if any.

If a software failure occurs in the tablet, it stops starting, "eternal loading" is in progress, or the device is locked with a graphic key - you have only one way out - to get into Recovery mode, ie. recovery mode. The Recovery menu can only be accessed when the tablet is turned off. To do this, use a special combination of simultaneously or sequentially pressed physical buttons on the tablet, which are located on the body of the device. This is usually the volume +/- rocker, power buttons, and / or Home key.The general procedure is as follows:

How to make a hard reset through the default Android settings
This is the easiest way to reset Android settings and we recommend using it first.
Go to the device menu - Settings - General settings. If you don't have such a subsection, then go back. The main thing is that there is a section “Archiving (Archiving) and reset” or Confidentiality next to it. In different versions of Android, there may be minor differences in the naming of the settings menu items.
Click on "Reset data" or "Reset device" and then "Delete all" to confirm the reset.

How to reset the settings through the hardware buttons on the phone.
A full reset and return to the factory version of Android is a magic wand for you in that case. Why it doesn't turn on is not so important anymore. So, how to reset the settings through the keys on the phone, in the off state:
If the phone is working, turn it off
Press and hold three buttons at the same time: Power + Home (Center) + Volume Up.
Next, you need to hold down three buttons on your phone: the power button, home (home, as a rule, is located on the front panel) and volume up. If there is no Home button, then try the option with the power button and volume up.
Release the “Power” button after “Samsung Galaxy ...” appears on the screen. Hold the rest of the buttons until Recovery appears (about 5-15 seconds).
As soon as the logo appears, release the power button (only it, hold the other buttons). The recovery menu should appear. How to throw off the settings through it, read on.
Resetting settings through Recovery
Menu control in Recovery mode is carried out via the volume down button. Select "Wipe data / factory reset" and press the Power button to confirm.
We agree with the operation (select Yes - Delete all user data) and confirm again.
We reboot the phone. To do this, in the menu, select the item "Reboot system now"
Hard reset (or reset the settings on Android) is an extreme measure to restore the original phone settings, provided by the developers.
The factory settings set in Android assume that the mobile device will work stably, predictably - everything as intended by the manufacturer. In case of any error, problems with the phones, you can roll back the settings to restore the operating system to the working state.
Why reset Android settings and when you need it
There are many good reasons why a factory reset can make a phone's life easier. Here are the most compelling reasons:
- Your Android starts to slow down terribly or applications glitch. Although Android works flawlessly, if you do not mow, sometimes inexplicable conflicts and application errors occur, when it is impossible to accurately identify the cause, but from the phone it does not solve the problem in any way.
- The phone simply stopped turning on correctly. In the process of experimentation or through carelessness, you made a mistake that, alas, became fatal. In this case, there is no choice but to reset the tablet or smartphone through the Recovery menu or the hardware buttons of the phone. In this case, resetting Android is almost the only way to return the phone from a brick state to a functioning gadget.
- Problems with unlocking a mobile device. However, we do not recommend resetting your phone if you cannot remember your pattern or password to log into your mobile device. Before that, we advise you to read the article on how to do it more competently:
- You want to zero your phone for sale. In fact, a factory reset can kill two birds with one stone. First, you optimize your phone to get it back to its most original condition. If you leave all applications, files, etc. on the phone, there is a risk that the mobile device will lose performance. The second point is that a hard reset deletes all files in the internal memory, which means you protect yourself from transferring personal data to the comm.
All these problems can be easily solved through a forced measure - namely, reset to factory settings.
The recovery procedure is quite safe, although it is almost a last resort in solving problems. It should not be performed unnecessarily.
In addition, before performing a hard reset, you need to know how to do it and take precautions. Which ones - read on.
Steps to take before performing a hard reset
There is a kind of checklist of necessary procedures that must be performed before starting the reset.
- important files on your phone. To avoid confusion and unpredictability, keep a copy of ALL important files on your computer anyway. Otherwise, it will be very difficult to recover data even in hot pursuit.
- Charge your phone to the maximum. Despite the fact that some models of android devices have built-in low battery protection, there are some nasty exceptions. Make sure the battery is fully charged - otherwise it may happen that during the reset the battery runs out and you turn the phone into a brick.
- For Android 5.1 and higher - remove the link to your Google account. This is new for relatively older versions of Android. You need to unlink your account before resetting, so as not to enter data after resetting. The fact is that if you forget your login information, you will not be able to resume access to the phone (you will need all the documents and a trip to the service center). This is for security reasons so that hackers cannot take over your phone using the factory reset function.
