How to Unlock Lenovo If You Forgot your PIN Code and Graphic Password - Unlock it in 15 Ways

Most people in the modern world have a huge amount of important information on their mobile devices. Therefore, every user first needs to think about protecting their gadget from unauthorized persons. For this purpose, there are passwords that can be set on a smartphone. One of these options is a graphic key.

But various unforeseen situations happen when the user can completely forget it. What to do in such cases? Fortunately, for the most forgetful, there is a solution that will help you reset your picture password - both from the Android system and from a specific brand of mobile device. Today we will talk about Lenovo devices. To understand how to remove a pattern lock from Lenovo, you should familiarize yourself with the list of possible options.

Reset Lenovo to Factory Settings to Unlock – Method #1

If you have tried all the methods and nothing helps, or if you do not care about the safety of the data on your device, you can perform a hard reset - reset to factory settings.

• Turn off your device.
• Remove the memory card from it.
• Switch to Recovery mode by simultaneously pressing one of the combinations:

• sound reduction + power;
• increase sound + power;
• volume increase + power + “Home”;
• volume reduction + power + “Home”;
• increase sound + decrease sound + power.

• In the service menu that opens, select Recovery. Control occurs using the volume keys.
• Tap on the command “Wipe data/factory reset”.
• Confirm the action “Yes”.

In a couple of minutes, your phone will be completely uninstalled. You will receive the device in the same condition in which you purchased it (of course, without a password).

Depending on the model of the Android smartphone, resetting the firmware or resetting the settings to factory settings is carried out differently.

Nokia

You will need to do the following:

• Connect the device to a computer that has access to the Internet.
• Install app Nokia PC Suite. It allows you to transfer files from your phone memory to your hard drive and perform other useful functions.

• Install Nokia Unlocker Tool to unlock.
• After recognizing the gadget in the Nokia PC Suite program, immediately activate the second utility.
• Request a code so that the utility can unlock the equipment.

If the described option does not help, then you need to contact the service to solve the problem.

Sony Ericsson

Devices from this manufacturer can be unlocked in two ways: via cable and PC, as well as through special software (SEMCtool_v8.4 or TMS 2.45). In the first case, you need to install the paid WotanClient program.

Samsung

A product from this manufacturer offers to create an account after purchase, which can save information in memory if a password or pattern is forgotten. The account is available after entering your login and password. First, you need to go to the Samsung account website, open the “Content and Services” tab and find your device. Press the “Unlock screen” button.

LG

LG has made the most complex protection, so to restore access you will have to use special codes. The main difficulty is that they are made for each specific phone model, so there is no general solution. It is recommended to contact the service center or store where the purchase was made. Employees will be able to help solve the current problem.

HTC

You can remove the password with the key on these phones using the proprietary PC utility HTC Sync:

• You need to connect the gadget to the PC.
• Install the HTC Sync and the Screen Lock Bypas utility.
• Reboot the device and unlock it.

If after these steps the password or key remains, it is recommended to repeat the procedure 1-2 times until functionality is restored.

Using Hard Reset

If the login and password from the Google system are lost or were not specified previously, the second method will allow you to remove the pattern key on a Lenovo tablet or any other gadget. But it is important to understand that all information from the device will be completely lost. This is a very radical method - a complete reset of the system to its initial state.

In order to start a “hard” reset, you must first prepare the device:

• You must turn off the device in order to get to the operating menu;
• After turning off, you need to hold down the volume control simultaneously with the power button. Further behavior of the system depends entirely on the software installed on the device. This manipulation sends the user straight to the “Recovery” mode, in which all work will be carried out.

The operating mode always has two states - “Custom recovery” and “TWRP recovery”. They differ slightly in navigation.

How to Unlock Lenovo Through Google Account – Method #2

If your mobile device has an Internet connection (via your operator's network or an automatic connection to Wi-Fi) and you have a Google account, then you can use the Find My Device service to unlock your smartphone.

REFERENCE: “Find My Device” from Google is a service that allows you to control your phone remotely, for example, when it is lost or stolen.

• Log into your Google account on your tablet or computer.
• In the menu, find the “Security” section and go to it.
• Next, find the “Your devices” item.
• Click on "Manage Devices".
• Select the device that is locked and tap “Erase all data from this device.”
• Confirm your intention.

After completing all the steps, the smartphone settings will be reset. It will need to be configured again.

Probability of successful unlocking

Unlocking a smartphone may not always be successful , but first you should use several methods. So, first, let’s find out how you can remove a graphic password:

• Using a Google or Android account;
• Using a special SMS Bypass program;
• Using the ADB Run debug bridge;
• Perform “Hard Reset”;
• Reflash the device;
• Contact support on the official website.

The first 4 methods were personally tested on a Lenovo smartphone

Unlock Lenovo Screen Using Google – Method #3

If your gadget has access to the Internet, it can be accessed through the Google system if the screen is locked.

IMPORTANT: This method can be used by owners of smartphones whose operating system versions are not newer than Android 5.0 (models before 2014).

• Enter the key, code or password incorrectly on the device screen 5 times until a message appears indicating that the device is temporarily blocked. The message “Forgot your password” or something similar should appear there.
• Click on the indicated inscription. A window will open in which you will be asked to enter registration data (password and login) for the Google account to which the device is linked.
• If you have forgotten the password for your Google account, try to recover it using one of the available methods (except “using your phone”) via a computer or tablet.
• When you enter your Google account login information on the screen of a locked smartphone, you will be asked to come up with a new combination to log into the device, and the phone will be unlocked.

TWRP recovery

In this mode, touch keys will be responsible for navigation. Here in the menu you need to activate the “WIPE” item.

To complete the operation, select “FACTORY RESET” from the list.

Don’t worry if the gadget reboot time takes longer: these are the consequences of the reset. When turned on, the system will reconfigure all software. In this way, you can reset the Lenovo graphic key if account access cannot be restored in any way. When purchasing a mobile device, it is recommended to immediately anticipate such situations and purchase a memory card in the kit so as not to worry about the possibility of losing information. And to save contacts you can use Google Cloud Server.

Call Lenovo from Another Device to Unlock – Method #4

Every smartphone user knows that in order to receive a call, your phone does not need to be unlocked. This trick can be used to gain access to the gadget’s system if you suddenly forget your pattern key or PIN code.

• Call your mobile from another number.
• Answer an incoming call on your device.
• After starting a conversation, the phone is unlocked. Open the top notification shade.
• Go to Settings.
• Disable the password.

IMPORTANT: This method is not suitable for gaining access to new generation phones. You can only try to use it if you have a very old Android.

Unlock pattern lock on Lenovo phone without data loss

I will not describe in more detail how to disable the pattern lock on a Lenovo smartphone or tablet here, since detailed instructions have already been written - here it is.

What is it? When you first start your Lenovo phone, in order to gain access to all functions, Android requires you to create or log in with an existing Gmail account.

I don’t want to do this, but now it’s even very useful. The fact is that then the phone is registered in a special service and you can control it via a computer from anywhere.

The only thing you need is for the Internet to work on your Lenovo smartphone or tablet, but if it doesn’t, you can connect it even if you forgot or forgot the pattern key.

How to do such a trick in Lenovo is described here. By following the link you will find three ways to get Internet on a locked Lenovo phone, without unlocking.

Next, follow the recommendations described in the previous section at the first link. If nothing comes of the idea, then we move on to the second option - with data loss.

Method 1: Try to reset your password.

The security system on Android Lenovo smartphones allows you to install a simple, but at the same time effective, pattern key on them, which provides it with protection from unwanted attacks on personal information. But it happens that your memory fails and you cannot remember it, being left alone with only a beautiful “piece of plastic” in which your blocked data is stored. How to remember a forgotten pattern key on Android or what to do to unlock your smartphone?

Method 1: Try to reset your password.

One of the ways to unlock a smartphone after a forgotten pattern key is to reset the security measures by logging into the device using the Google account that is registered on the phone.

The peculiarity of this method is that to unlock it, it is necessary that there is at least some connection to the Internet (Wi-Fi or mobile Internet) on the phone.

If the Internet is working and your Google account is confirmed, you will immediately be able to change the existing key or completely disable the phone locking service.

Method 2 - data reset with complete loss of information.

If you still can’t recover your password by entering your Google account, the most radical method is a hard reset. It is worth paying attention to the fact that with a hard reboot, you will lose all the information stored on your device in the internal memory: photos, videos, various documents, SMS, address book contacts and other materials.

To learn how to do a hard reset (full reset) on your phone, read the article: how to do a Hard Reset on Lenovo

In the modern world, information recorded and stored on various electronic media can be more valuable than the device itself on which it is located. Therefore, it is very important to ensure reliable protection in case of loss or theft of your device. Indeed, thanks to modern technologies, a criminal, having acquired a gadget, can gain access to both personal data and electronic payment systems. Mobile devices are especially vulnerable in this regard.

Removing Lenovo Graphic Password Using PC – Method #5

This option will help protect data on your smartphone if you have forgotten your digital password or pattern key. There is a file in the phone's memory that is responsible for the operation of the pattern key. If you delete it, the system will not ask for a key to enter.

HELP: The method will work if the USB Debugging mode is active on the gadget. It can be enabled through the “Developer Menu”.

• Connect your device using a USB cable to your computer or laptop.
• Download and install the adb run program.
• Run the utility and enter the request “adbBLOCK GEST”.
• Confirm deleting the file.

Custom recovery

The volume key controls this menu. Using it, you need to move to the “wipe data/factory reset” item. To confirm the action, you need to press the power button.

A new menu section now opens. Using the same key responsible for the volume, select “Yes - delete all user data”. And we use the same power button to confirm our choice.

After all the formatting steps, all that remains is to select “reboot system now”. This will trigger a complete reboot of the entire system.

Unlock Lenovo Using Internet Connection – Method #6

This method of unlocking a smartphone screen also involves using a Google account. The main thing is not only to enter the correct information to log into your account, but also to ensure access to the Internet.

• Reboot your device.
• After switching on, a “curtain” will appear at the top of the display. Unfold it.
• Tap "Mobile Data" or the "Wi-Fi" button.

If you can’t pull out the curtain, you can use the system code to ensure a connection via Wi-Fi:

• Tap the "Emergency Call" button (located on the lock screen).
• Enter the command: *#*#7378423#*#*.
• Go to the Service Tests/ Service Provider tab.
• Next - “WLAN”.
• Connect to Wi-Fi.

HELP: If it is not possible to provide access to Wi-Fi, you can insert a SIM card with a working Internet connection into the device and log into your Google account.

Unlock Lenovo Through Smart Lock Options – Method #7

This option for resetting a locked screen password is only possible on phone models no older than 2015 (Android 5.0 and older). It was from this time that the Smart Lock function became available on electronic devices.

HELP: To use this method, you must have set up the Smart Lock feature in advance. You can find the option in the gadget settings in the section responsible for the lock screen and security.

The Smart Lock feature allows you to set your phone lock settings depending on three parameters:

• "Trusted devices";
• "Safe Places";
• “Physical contact” / “Face recognition”.

Use Batteries to Unlock Lenovo - Method #8

You can unlock your gadget's screen if you have forgotten your PIN code through the power management system.

ATTENTION: This method does not work on modern devices. You can try your luck with this method only on older Androids.

• Wait until the phone's charge drops to 10-15%.
• When the low battery message appears, click on the link that takes you to the battery menu (power management settings).
• From there, go to the device security section.
• Disable the password.

Change Lenovo Password Using ADB Run Program – Method #9

Unlocking using the special ADB Run utility will only work if USB debugging was previously enabled on your device.

HELP: USB debugging is used to set up applications and change settings on an Android phone using a special program on a PC. It can be enabled using the hidden “Developer Menu”. For example, for phones with Android below version 7.1, this can be done using the following chain of commands: “Menu” - “Settings” - “About smartphone” - “Build number”. You need to tap on the last item 7-10 times. Next: “Settings” – “For Developers” and check the box next to “USB Debugging”.

Flashing Lenovo to Unlock Password – Method #10

This method is universal. It will work on any smartphone model. The bottom line is that the device's operating system must be completely uninstalled and reinstalled. Of course, all files and data from the device (including the specified password) will be deleted along with the OS.

Preparatory steps:

• Charge the device's battery or make sure it has at least 50% charge;
• Find out the current OS version for your smartphone (“Menu” – “Settings” – “About phone”).

Option 1. Through a computer

There are many programs with which you can flash an Android phone: Fastboot, Odin, KDZ Updater, Flash Tool, etc.

• Download one of the specified programs to your PC (it is better to download to drive C so that the path to it is C:\Android). We will look at the process using Fastboot as an example.
• Connect your smartphone using a USB cable to your PC. The automatic installation of drivers should begin.
• Download the firmware that matches your phone version. It should download in a zip archive.
• Move the archive to the C:\Android folder.
• Unlock the bootloader on your phone:

• go to the Start menu;
• enter “CMD” into the search engine;
• select cmd.exe and right-click on the file;
• further – “run as administrator”;
• in the command line enter C:\Android\Tools;
• press Enter;
• enter the command fastboot devices.

• If the program correctly recognizes your device, its code will appear. This means that the device is ready for firmware. If the message “waiting for device” is displayed, you need to disconnect the device and repeat the above steps again.
• If everything works, enter the command “fastboot update firmware file name.zip”.
• The Android firmware process should start. When the procedure is finished, restart your smartphone.

Option 2. Through Recovery

Recovery is a special mode on your smartphone. To get into it, you need to turn off the phone and hold down certain buttons.

HELP: Each Android device model has its own buttons. This could be the power + volume up key; Home button + power + volume up, etc.

• Download the firmware file.
• Transfer it to the root system of your smartphone using a USB cable.
• Go to Recovery mode.
• Find the section with the firmware (“apply update from externel storage”, “apply update from sdcard”, etc.).
• Select the downloaded file and tap on it. The firmware process will begin.

Option 3. Via ROM MANAGER

This firmware method is not popular because Root rights are required to use ROM Manager.

• Download the ROM Manager program.
• Download the required firmware for your gadget.
• Connect your smartphone to your PC using a USB cable.
• Open the utility.
• Copy the zip file with the firmware to your phone's memory.
• In the program menu, click on “Install ROM from SD card”.
• Find the archive with the firmware and tap on it.
• Next - “Reboot and installation”.
• Check the box next to “Save current ROM” (this will allow you to restore the previous version of the OS if something goes wrong).
• Confirm your actions with the “Ok” button.

ATTENTION: Reflashing is a radical method. In the hands of an inexperienced user, it can be detrimental to the stable operation of the device. Therefore, if you do not understand smartphones and are not confident in your abilities, it is better to contact a specialist.

Method number 5. Firmware update

Another answer to the question of how to unlock Lenovo. In this case, the phone will also be pristine. There will be nothing left. Only what will be on the flash drive. Unfortunately, there are no universal instructions for flashing Lenovo devices. It all depends on the specific model: some require firmware via a computer, while others only need a flash drive with the firmware copied onto it. However, an approximate algorithm of actions is as follows:

1. We look for the required firmware on the Internet and download it.
2. Download and install the necessary drivers and software.
3. We flash the phone according to individual instructions.
4. We load the device, enter the necessary data and configure it.
5. We use it.

Of course, the algorithm described above will not answer the question of how to unlock the Lenovo phone password. To do this, you need special instructions based on the model of the device. In search of this instruction, you can search forums on firmware for mobile devices. There you can also find the necessary firmware and necessary software.

Ask a Question

Question to the expert

Is there an additional way to remove the lock without resetting the settings?

Yes. There is an alternative option that has not yet been discussed in the material. However, its performance is questionable. Still, it's worth a try. To unlock, you need to call your smartphone, pick up the phone, and then from the call menu go to the device settings.

What to do if none of the suggested methods help?

This situation arises when a person does not even remember the settings of his Google account. To avoid performing a factory reset with subsequent data loss, you need to restore your Google account on the company’s official website and try to remove the lock through it. This method was described in more detail at the very beginning.

Should I contact Lenovo directly?

Yes. In some cases, the company’s office actually helps solve the problem with unlocking your smartphone. But to do this, you need to prove legal ownership of the device by providing a receipt of purchase.

Can specialists from the service center help?

Yes, but with a high degree of probability we can say that they will simply try to reset the smartphone to factory settings. You can perform this operation yourself.
