Methods for removing a pattern key on Lenovo devices

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.

Other problems

There are also other situations, for example:

1. The tablet turns on and off, this can also be related to “power” and is often found on Prestige and Asus. If the tablet turns off by itself, the “double click” is to blame, something that PC users often encounter when the system perceives one mouse click as two. When the tablet turns on and locks in an instant, the “power” is not broken, but the whole problem lies in the sensor, which should be replaced at the nearest service center.
2. What to do if the tablet reacts every time to presses? The root of the problem is the same as in the previous case, so either resolder the part if there is a similar one, or immediately ask for help from specialists.
3. What to do if the tablet sees “phantom” clicks? This often occurs when headphones and other devices are connected to it, and the problem can be either in shorted contacts or in a malfunction of the equipment itself, which simply sends incorrect signals. If we are talking about headphones, try connecting others and check the operation again.

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.

Contacting technical support

All well-known manufacturers of mobile equipment have their own websites with technical support. When you contact us, our specialists will help you recover the password on your device. Step sequence:

1. Find the interactive “Support” tab in the menu of the company’s official website.
2. Find the “Contacts” item or find the “Search for a solution” link in the product information block.
3. After the transition, the “Contact Technical Support” tab will open.
4. You can choose a quick option by calling the contact phone number. If you wish to receive text instructions, use “Chat” or “Email”.
5. Please describe the situation in as much detail as possible in the contact form for a faster response.

The response usually comes promptly with guidance and recommendations. Clarification questions are possible.

Resetting a graphic password via a USB connection to a computer

A more complex and usually always effective method is to use your PC.

• Take the cable and connect your device to your computer. If you receive a message about enabling debugging, then everything is going according to plan. If it is not there, then this function is disabled for you, and this method is not suitable.
• Let all the necessary actions on the screen complete and go online to download yourself a program called Adb.
• Run it and then open the command line.
• Now you need to put what is written below into it. You can rewrite it or just copy it.

adb shell

cd/data/data/com.android.providers.setting/databases

sqlite3.settings.db

update system set value=o where name='lock_pattern_autolock';

update system set value=o where name='lockscreen.lockedoutpermanently';

.quit

• All that remains is to enable the device reboot mode, and the protection will be disabled.

What to do if you forgot your password: general instructions

1. With the device turned off, press and hold the top volume rocker (volume up button) + the Home button (usually a large central button or a button with a house drawn on it) + the power button. If there is no Home button, then only the volume and Power buttons.
2. After vibration or the logo appears on the screen, release all buttons.
3. Next, using the same volume rocker, select the line “Wipe data/factory reset” and confirm the choice with the “Home” button or the “Power” button (depending on the model).

4. After this, we find ourselves in the next menu, where in the long list of “No” items there is an item “Yes - delete all user data”, which we select. After performing the reset, the first menu will be displayed where we reboot the system by selecting “reboot system now”.

This instruction should apply to all devices from Samsung, LG, HTC.

Software from manufacturers can also help in this matter. For Sony devices this is SonyEricsson PC Suite, for Huawei it is HiSuite, for Samsung the program is called Kies. And, of course, start by reading the instructions for your device, perhaps this will allow you to quickly and effectively solve the problem of blocking your device.

A pattern key for a tablet is a protection that blocks other users from entering your device, in particular if it is stolen or lost. In simple words, a graphic key is a password that does not consist of numbers, but is a combination of nine circles, connecting which in a sequence specified by the owner of the gadget provides access to the device.

It is important to know: in some cases, trying to enter the security key may take forever. But, often, after several attempts, the program automatically blocks the gadget, believing that it is protecting it from an attacker who has attempted to steal the data stored in the device’s memory. In this case, trouble begins, especially if you need to use the tablet urgently. How to remove graphic keys will be discussed below.

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.

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.

By call

What should you do if you forgot your pattern key and all your account passwords, and the developer menu method seems too complicated? There is an even simpler action, but it is only suitable for phones running older versions of Android. To check this, you just need to call your smartphone. From an incoming call, it becomes possible to go to the main menu of the device without entering a graphic password via the “Home” key. After this, just go to settings and reset the key, or even better, disable it completely.

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 quickly bypass this breakdown in the future

If you managed to start the tablet and bypass the lock screen without a button, then you do not want to repeat the entire procedure. Fortunately, there are several applications that allow you to turn on the gadget even in such situations, some of them do this by reassigning functions to other “triggers,” and some work using a camera and proximity sensors (as well as pressure in the latest snow leopard).

One of the best software of this kind will be Gravity Screen, which saves you from a critical situation and is useful even during normal use.

And a regular gyroscope is used to turn it on, so after a quick setup, the gadget will automatically learn to turn off in the case and on the table, and turn on in your hands.

There are also additional functions, thanks to which you only need to shake the device or perform other simple actions for the display to work if the power button does not work.

If you are not going to take electronics to a service center, but still want to use it in the future, disassemble it. Sometimes situations happen, such as when the problem is not in the lock button, but in the inability to turn on the device without a battery, broken or previously removed. Then none of the methods will help you, because powering the accessory without a battery is simply impossible.

And if you are worried about how to turn on a device without a power button that has fallen out or become deformed, then simply find a piece of plastic, and then replace the damaged part in the device. But it happens that the problem is not in the hardware, then to fix it it is enough to use an Ammeter and check whether the current flows when you press the trigger. If this is the case, but Lenovo does not respond, then there is no other choice but to launch Android using a PC and reflash it. We talked above about how to launch Android from a PC. If after this it does not turn on, then most likely it can no longer be repaired.

Using PC and ADB

In the case when unlocking the graphic password on Lenovo was unsuccessful, there remains one, the most difficult, method - using a PC and a special program. What exactly is required for this:

• Work computer;
• USB cable;
• Download special software - ADB;
• Find and download the script;
• Drivers for more convenient work with the Android system.

The procedure for resetting is as follows:

• If the program is in an archive, unpack it to hard drive “C”;
• You need to place the adbBLOCK GEST script into the already unpacked folder;
• After this, on the mobile device with which the unlocking process will be carried out, USB debugging should be activated;
• This is done in one of three ways, depending on the system:

1. To do this, in the “Settings” menu, select the “For Developers” item, and then select the defer function.
2. Through the settings, select “Development” and “Debugging”.
3. Using the settings, go to the “System” menu, then “About smartphone”. In the window that opens, click on the build number about 7–10 times;

• Now you can safely connect your mobile device to your PC via a USB cable. It is important that if the gadget cannot be manipulated and there is no way to get into “Settings” due to the pattern key, then you can only hope that debugging is already active;
• You need to run the finished script on your computer. He will offer to get rid of the GESTURE.KEY file. Use the “Enter” key to confirm the deletion;
• After all the actions, the script will ask you to reboot the device. We confirm again and during the reboot, immediately disconnect the smartphone or tablet from the PC;
• When the gadget turns on, it will prompt you to enter a graphic password to unlock it. You can enter whatever you want. The device should unlock.

Attention! If this method does not work, you can try repeating all the steps in Recovery mode.

Using your Gmail account

If the Google system contains data about the user account, then it becomes possible to reset the graphic password through the account. Before unlocking the pattern key on Lenovo, it is recommended that you familiarize yourself with the simple procedure:

• First, you need to call the auxiliary panel to recover your Google account. To do this, you will have to enter the wrong pattern until the network login form appears on the screen;
• The first thing you will need when logging in is your account login and password;
• After this data has been correctly specified, the system will prompt the user to complete activation on behalf of the administrator;
• All you have to do is hold down the key responsible for the “Administrator” mode, and all sorts of passwords will be removed from the gadget.

This method is one of the simplest, but there is a small catch. Before you unlock the pattern on Lenovo, you need to remember whether your account information was entered during the initial setup of the gadget.

Unlocking your phone

The security system on Lenovo phones running Android OS makes it possible to use a simple graphic key as a security mechanism, which will avoid unauthorized access to information located on the device. But it happens that your memory fails and you cannot remember the password. What to do in such cases?

Method No. 1

The Lenovo manufacturer provides no more than 5 attempts to unlock a smartphone using a pattern key. When all attempts have been exhausted, enter any combination, wait half a minute and confirm that the password is forgotten. Then you need to enter the details of your Google account that you use on your phone. Once your Google account has been verified, you will be able to unlock your phone or change your pattern.

Method No. 2

How to unlock a device if you have forgotten both the pattern key and the password for your Google account? Try calling your number from another phone and, having accepted an incoming call on a locked smartphone, open the device settings. Having found the pattern key in the security settings, disable the option. Then we turn off the ringer and you can use the phone freely again.

Method No. 3

If none of the above methods help, then you will have to resort to the most radical option, namely a hard reset, that is, resetting all settings to the factory level. It’s worth noting right away that in this case, you may lose data that was on the phone’s internal memory (if you don’t make a backup first), but you will regain control of the gadget.

Reset the device to factory settings

If the password data has been lost and recovery through the account does not help, then resetting the settings through Recovery may help.

Recovery allows you to go to the developer menu and will be useful for those users whose device is not only locked, but also malfunctions from time to time (reboots, freezes, etc.). So, for this you need:

1. Disconnect the device and go to the Recovery menu.

For different manufacturers, you can get to this menu in different ways.

SAMSUNG	Volume up key - power button.
LENOVO	Volume down key - power button.
ASUS	Volume up key - volume down key
SONY	Power button-home-volume up key.
XIAOMI	Volume down key - volume up key.

Navigation through the developer menu is carried out using the volume keys, and selection must be made with the power button.

1. After completing all the preparatory procedures, the user finds himself in a menu called Recovery, where he needs to launch the third item in the operating menu (wipe data factory reset or similar. Not always the third)
2. Next, all that remains is to confirm your choice and reboot the device using reboot.

Using a service center

If it was not possible to remove the graphic key from Android, then there are specialized centers for such cases. They have programs at their disposal that allow you to remove a forgotten password without consequences. Of course, you can’t do this for free, but you will save time and nerves. To avoid expenses, it is recommended to write down passwords or choose devices with a built-in fingerprint sensor. This is the best way to protect important information from prying eyes.

How can you unlock your smartphone?

So, how to unlock Lenovo phone if you forgot your password or pattern? There are several ways to do this. They all differ in degree of complexity and effectiveness. If one of them does not help, then you can always try another. These are the methods:

• Using a Google Account. It only works if the user has linked the device to a Google account. Requires an active Internet connection.
• Using special programs. Some file managers can work from recovery and edit system files. With their help you can remove the blocking. It only works if a pattern has been installed to unlock the smartphone.
• Feint with the bell. It is based on a well-known Android vulnerability, which allows you to enter the gadget’s settings menu during a call to this device. Used quite often.
• Reset. The most radical method that unlocks the device with a 100% guarantee. But this will delete all user data. Therefore, it should be used as a last resort.
• Firmware. It is used only as a last resort, if nothing else helps. Can fix many problems. But the wrong firmware can kill the device.

All of the above options are answers to the question of how to unlock the key on a Lenovo phone. Some of them should be used only in extreme cases. Others are absolutely safe. We'll look at everything. Let's start with the simplest and most accessible.

Flashing method

Reflashing the device is the most difficult and risky method. You can only resort to it if you have forgotten the pattern key, you do not have the Internet and you do not know how to unlock the tablet in other ways. It is assumed that you know how to flash Android devices and that you already have the appropriate firmware with all the necessary tools.

The official source of original firmware is the website of the manufacturer of your device. All other sources can aggravate the problem, turning the gadget into a “brick”.

The following software is used to flash specific models of Android mobile devices:

• For Samsung – the Odin utility, which we have already mentioned.
• For LG – KDZ Updater.
• For Sony – Flsahtool.
• For devices of different brands - FastBoot from the Android SDK.
• For devices on MediaTek chips (which are mainly used on Chinese gadgets) – SP Flash Tool.

There are no universal instructions for installing the firmware - you must first find it on the website of the developer of the flash utility and study it in detail. If everything goes without incident, you will receive a pristine tablet with a brand new Android OS. There will be no trace left of the graphic key on it.

SIM card for bypassing paths

If the tablet has a SIM card slot and is actively used, you can try to bypass the system protection. A prerequisite is an installed phone application. This method is good for any tablet, including Samsung. This is a big “hole” in the security of the operating system, which is why Android programmers removed a similar option from the latest versions of the platform. Try the following route:

1. Make sure you have or install an active SIM card
2. Make a call to the device from any other number
3. Accept the call and minimize the phone application with the home button
4. In the “conversation” state, any device application is available to the user
5. Take the opportunity to unlock your tablet

For better or worse, this method is not available on the latest versions and it will not be possible to remove the PIN code.
