How to unlock the tablet screen? How to lock and unlock the screen. How to unlock a tablet - the most common methods Unlock a tablet on windows
There are situations when, when you turn on the gadget, you find that it is blocked. Two questions immediately arise in my head: why did this happen and how to quickly unlock the tablet. We note right away that even if the device is under warranty, no one will help you solve this problem for free. You can deal with the "breakdown" yourself.
Types of password protection in tablets
To protect data from prying eyes, a special protection was developed - blocking the device.
Regardless of the device model and operating system, two types of encoding are used:
- Graphic key - a password in the form of an individual combination of connections of 9 circles;
"Pattern example"
- A text code is a set of numbers or letters that gives access to tablet data.
Reasons for blocking the tablet
If you enter the security key or password incorrectly several times in a row, the system will automatically lock the device. So it protects data from intruders.
It also happens that the virus blocked the browser on the tablet. This happens according to the following scheme:
- When accessing an infected site, a dangerous program is downloaded;
- It changes the DNS server address. Because of this, the user cannot navigate to other pages and turn off the browser;
- When checking antivirus program, the system does not detect any viruses. "Pests" are trained to hide from the scanner.
As a result, the user sees a message on the screen: “The browser is blocked by the Ministry of Internal Affairs”, the amount of the payment penalty and a timer. This is how cyber scammers work, extorting money for unlocking the gadget. It is worth noting that in no case can you send SMS to the specified number or fulfill the conditions for paying a fine.
"Do not send money if you see this kind of message"
You can solve the problem in a different way, even without the participation of service centers.
What to do if a virus has blocked the gadget's browser
Sometimes these kinds of messages appear in the form of pop-ups or spam. In this case, try pressing the back key and close the site. If everything remains unchanged and it was not possible to return the ability to control the tablet, then, depending on the installed operating system, other actions must be taken.
Android
There are several ways to solve the problem.
Option 1: use Google account. Follow these steps:
- Login to your account via Play market on another device;
- Install any antivirus. When you need to specify the download location, select the infected tablet;
- Reboot the infected gadget. He will turn on background and the antivirus will begin to perform its task. Visually on the screen you will not notice the changes for another 10 minutes;
- After the specified time, restart the device again.
Option 2: manipulations through the Recovery menu.
"This is what the Recovery menu looks like"
Follow instructions:
- Turn off the tablet and hold down two keys: reset + volume up for 10 seconds;
- Activate safe mode downloads;
- If the system gave access to actions, go to the settings and remove the application, after installing which a blocking message appeared.
If the delete or pause keys do not respond, then the virus has seized administrator rights. In this case, you need to act like this:
- Reboot your device in safe mode again;
- Go to the Play Market and download the antivirus;
- Restart the device again, and it will activate the antivirus scan;
- And reboot a third time.
Option 3 - cardinal: return to factory settings. Follow instructions:
When resetting to factory settings, all tablet data will be deleted. The only exception is information that was stored on a memory card.
iOS
Gadgets running on iOS are much more fortunate, the virus does not block the system completely, the extortion message appears only as a pop-up window. To delete it, you need to follow this scheme: “Settings” → browser menu → “Clear history and site data”.
Unlock bootloader, how to get root rights
Most of the tablet unlocking methods described below cannot be performed without obtaining root rights. Therefore, the first thing to do if the password has been forgotten is to unlock the bootloader or bootloader.
Follow instructions:
Ways to unlock the tablet if you forgot your password
Below are the main ways to unlock your tablet if you forgot your password. They differ in:
- Degrees of difficulty;
- Features do not damage the information stored on the device.
Through Google account
This option is the most optimal for solving the access problem. You need to act according to the following pattern:
- Enter the wrong password 5 times;
- The message "Forgot graphic key? You need to click on it;
- Enter your Google account username and password;
- An email will be sent to you with instructions on how to unlock it.
Insert SIM card
If the functionality of the tablet allows you to use a SIM card, this is a serious security hole. It can be used to restore access. It is enough to install a SIM card in the slot and receive a call from another number. During a call, go to "Settings" and unlock.
Unfortunately, the latest models this opportunity has been eliminated.
Install adb run
This method can be taken only after obtaining root rights. Its essence is to remove keys that contain information about the password:
- key - for graphical unlocking of the screen;
- key - text code.
After unlocking the bootloader, do the following:
- Confirm your intention to delete the file.
Resetting the system to factory settings
When nothing else has worked, a reset should fix the problem. When using it, all data that was stored on the tablet will be lost. Resetting to factory settings is called a Hard Reset. Follow instructions:
- Put the gadget into Recovery mode (hold down 2 keys: reset + volume up and select the appropriate item);
- From the menu that appears, select the item wipe data factory reset;
- Confirm selection.
Reflash device
If you didn’t manage to switch to Recovery mode, you will have to. For this you need:
- Find the current firmware version of your model on the official website of the manufacturer;
- Connect the gadget to the computer and run the previously downloaded OS.
If the process of finding and installing a new operating system is difficult for you, you can always contact service center specialists.
As you can see, there are many options for unlocking the tablet, the main thing is not to panic and find the right one for you.
The graphic key for the tablet is protection, which blocks access from other users to your device, in particular if it is stolen or lost. In simple words, a graphic key is password, consisting not of numbers, but representing combination of nine circles, connecting which in the sequence specified by the owner of the gadget provides access to the device.
It's important to know: In some cases, you can try to enter the security key indefinitely. But, often, after several attempts, the program automatically blocks gadget, believing that it protects 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 take off graphic keys will be discussed a little lower.
How to unlock tablet
As a rule, there are two ways to protect your data on a tablet - this is graphic key and password(fingerprint scanners familiar on smartphones have not yet been deeply integrated into the world of tablets). So, how can you unlock a protected tablet with a password?
Password represents a four-digit numeric or alphanumeric combination that was previously set by the user (for example, pin code 1111 or password ab11).
It's important to know: as you can see, the methods of activating the key and password are the same and carry identical functionality, and different they are interconnected exclusively by the input method and each user chooses for himself which of the methods is more convenient for him to unlock.
Well, now you should move on to a detailed description of how to unlock the device if the password data has been lost or simply forgotten.
Using a Google account
Google account verification is the most optimal a way to unlock the tablet, allowing you to access the device by sending an e-mail. To carry out this procedure necessary:
Reset the device to factory settings
If the password information was lost, and account recovery does not help, in this case, resetting via Recovery.
Recovery allows you to go to developer menu and it will be useful to those users whose device is not only blocked, but also malfunctions from time to time (reboots, freezes, etc.). So for this necessary:
- Turn off the device and go to recovery menu.
For different manufacturers, you can get into this menu in different ways.
Navigation on the developers menu is carried out with the keys volume, and the choice must be made with the button nutrition.
Reflashing the device
If the user failed to enter the Recovery menu, then the only thing left is reflash device, as this is the only way to start using it from scratch. For flashing would need:
- Find required version firmware for the device (firmware is selected depending on the manufacturer).
- Now, on the official website you need to download software required to control the tablet system.
- Next, it is necessary to plug device to a personal computer and run the previously downloaded software. It will automatically detect the user's device and offer to start updating the OS.
- After that, the firmware starts boot and installed on the tablet.
Removing gesture.key and password.key
gesture key is a file in the tablet system that stores pattern data, and password.key- this is a similar file, but it contains data about the password. In order to restore access to the tablet, you must delete one of these files.
Deleting files:
- First of all, it is necessary get rights superuser ( root law). For this you need to go settings— About device— Firmware version(you need to tap several times until the corresponding inscription appears. New models require special software).
- Next, you need to go to Recovery menu.
- Then you need to choose file manager and select the files to be deleted.
- Remains only confirm your actions and restart the tablet.
The sound of the drain pump
The sound of the pump, if it occurs, is immediately audible and noticeable. If there is no sound, the pump is not working. We are looking for how to separately turn on the water drain program. To do this, you will have to press a few buttons to launch it. After the program has been turned on by you, after 1-3 seconds the pump should start working. If everything is done correctly, and the pump is operational, a buzzing sound will appear. If you did not hear any buzzing or other sounds when you turned on the program, the pump is probably faulty.

Washing machine motor failure
Engine repair. If no fault was found, the block with wires must be disconnected from the electric motor. We carefully remove it. We visually evaluate the engine. It may have melting, cracks, and other effects that clearly hint at damage. We call the windings of the tachogenerator and the engine. It is important to understand that you can fully study how the engine works correctly and whether there is a malfunction, only at the stand. If rotation does not occur, the fault may be concentrated not only in the engine. Sometimes the reason is a non-working electronic module, which can only be checked initially with a stand. If a short circuit occurred in the engine, the module could be damaged, while the engine remained operational. We are probably stopping at this, since there is no access to professional equipment with which it would be possible to check the performance of individual elements of the washing machine.

The washing machine hums, makes noise during the spin cycle, rumbles, emits the roar of a jet aircraft.
If during operation the washing machine makes noise, making unusual sounds, it's time to pay special attention to this. Noise can be called any sound that you have not observed before. In this case, a visible breakdown or lack of functionality may not be observed, but the appearance of strange sounds indicates that it is time to look for a malfunction. It is important to understand that a new machine that has just been brought in must be inspected for the presence of shipping bolts. If they are forgotten to be removed, noise and vibration are inevitable. So, let's begin! We turn the drum of the washing machine and listen to extraneous sounds.
When rotating, you hear extraneous noise, hum, rolling balls, does the drum move unevenly with slight jamming?If the drum is spinning and there are unusual sounds, including vibration, it's time to check the bearing assembly. If it malfunctions, you will have to replace the node.

Washing machine counterweight unscrewed
Mounting counterweights must also be of high quality. If they are "loose", it's time to eliminate this defect. For example, balancing stones are attached with three bolts). In some cases, you can see that the bolts that attach the stones are completely absent. In this case, the connectors for fastening will be visible. The bolts need to be found and put in place - they probably just untwisted. The fact that the bolts are partially untwisted can be indicated by a roar heard during the operation of the washing machine. To check the bolts, you can simply push the drum. If it is secured, the bolts are in order. If moved, there is a defect. It is important to remember that the tank should not rub against the walls of the washing machine.

Checking shock absorbers. If vibration or excessive noise is heard during the spin cycle, there may be a problem with the shock absorbers. Sometimes a knock is heard. Now we check the performance. Remove the top cover. Click on the tank, move it five to seven centimeters down. A normal reaction will be observed if the tank rises sharply, bouncing a little and stopping in its normal place. If this does not happen, you need to replace the part.

Washing machine does not turn on
Nowadays, the information that is stored on the device can cost much more than the media itself. The more important it becomes to protect important data in case of loss or theft of the device. After all, with the modern development of remote (“cloud”) technologies, having taken possession of the device, the attacker gains access not only to the information that is stored on the device directly, but also to the family photo archive, accounts social networks and even to bank accounts and electronic payment systems. This is especially true for mobile devices- laptops, smartphones and tablets. Let's dwell on the latter.
Protection against unauthorized access for tablets, as a rule, are passwords in the form of a traditional text code or the so-called graphic key - a curved line of a special shape that must be “drawn” with a finger on the device screen. But, unfortunately, it is not uncommon for a password to “protect” the device not from an attacker, but from the owner himself.
This can happen for a variety of reasons, because progress has made miniature computers available to the public. So, older people can forget the password. Children, out of curiosity, sometimes climb into such a jungle of menus and settings, the existence of which not every adult was aware of. Moreover, it doesn’t cost them anything to casually install a graphic key or change the text code, without even wanting it and not understanding what they did. What to do in this case, how to unlock the tablet?
If some five or six years ago, diversity reigned in the mobile device market, now “exotic” makes up a few percent, while the main part of the tablet market is divided among themselves:
- devices of the Apple family - the well-known iPads;
- other manufacturers whose devices are based on the Android operating system.
If in the case of "apple" products, the unlocking procedure is fairly standard, then tablets with a green robot on board have many features depending on the manufacturer, version of the operating system, etc. However, there are still some basic ways to unlock tablets based on Android in cases where the password is forgotten. Let's consider these methods.
Unblocking with a Google Account
It is no secret that the Android operating system is developed by the famous Internet monster Google. If you managed to use your tablet at least a little, then you probably got a Google account, without which it is impossible to fully use the Play Market Android app store, Gmail, YouTube video service and many other online services. Among other things, a Google account allows you to restore access to the tablet.
What exactly is required of you?
- You need to enter the wrong pattern five times. And it does not matter whether you will try to remember the real password (it is possible that in these five attempts you will remember it and the problem will be solved by itself) or simply enter an arbitrary key five times.
- If the miracle did not happen, after the fifth attempt the screen will be permanently blocked. But if you look closely, from the edge of the screen (usually at the bottom) there will be an offer to restore access. For example, the inscription will appear: “Forgot the graphic key?” When you click on it, you will be prompted to enter your Google mail address and password from it. You need to enter the email address that was used on this device.
- In case of successful authorization, the device will be unlocked, and you can enter a new password to replace the forgotten one or cancel the device lock altogether.
"Call a Friend"
This way to unlock the device is suitable for owners of tablets, the design of which provides for the installation of a SIM card. Typically, a SIM card in tablets is used to connect to the Internet via a mobile network, but no one bothers to install the "phone" application and use the device like a large smartphone. Of course, you can use this unlock method only if you have installed phone application before the device was blocked.
In this situation, the winners are the owners of tablets with operating systems old versions: Older versions of Android already have the phone app installed out of the box. However, many modern tablets, for example, some Samsung models, also provide the ability to make phone calls.
So, your locked tablet has a SIM card (or at least the ability to install one) and an application that allows you to make and receive calls. We do this:
- If there is no SIM card in the tablet, but the design requires its installation, you need to install any active SIM card, for example, from your phone.
- Using any telephone (even a landline) you need to call the phone number of the card currently installed in the tablet. We accept a call (“pick up the phone”) on the tablet, after which we turn off the phone application with the “home” button (home) on the screen or device case.
- Everything! As long as you are off-hook, you have full access to your tablet and the ability to unblock it.
Unfortunately (or fortunately), most modern Android devices do not have this option to unlock the device, since it allows you to easily bypass the protection of a found or stolen tablet. So this method is not suitable for everyone.
Full reset
If other methods did not help, you will have to move on to drastic measures, the simplest of which is a hard reset (hard reset or Wipe).
Important! Hard reset entails the complete removal of all data on the device. If the tablet contains important data, use a more gentle unlocking method or contact specialists.
Full reset of the tablet, return to factory settings:
- Once again, we are finally convinced that there is no data on the tablet, the loss of which will be painful for us, because the operation is irreversible.
- We start the recovery mode (recovery mode). Starting this mode may differ for different devices, but usually requires the simultaneous pressing of all the device's hardware keys (that is, the "live" keys on the case, and not the icons on the screen) and holding for some time.
- After enabling recovery mode in the menu that appears, select the item Wipe data / factory reset and confirm the action.
- We reboot the tablet.
Conclusion
We have considered only the simplest ways to unlock a tablet that is locked with a password. These methods do not require special knowledge, skills, and software and equipment. Of course, the tools and set of methods for specialists is much wider. Therefore, if you could not solve the problem on your own simple ways, it is better to seek qualified help.
A tablet is a very convenient thing for a modern person. A lot of functions combined in one device pleases any tablet owner. However, sometimes unforeseen situations arise: you turn on the tablet, and it is blocked, and you do not know how to fix it.
This topic applies to most tablet models based on the Android system. What to do if the tablet is blocked? This article will talk about ways to restore access to the device.
Reasons why the tablet is blocked
The main reason for blocking the device is an authentication problem. In other words, if you forget your password or the so-called login pattern, you will not be able to use your tablet. A similar situation (when the tablet is blocked) can occur with models from any manufacturer: Samsung (Samsung), Acer, Lenovo, DNS and less common brands Texet, Explay, Prestigio, etc.
Another reason is also possible: the Android is infected with a virus. Malware penetrates the system and blocks the tablet, demanding to send SMS. In no case should you send an SMS message to the required number. We offer several proven ways to solve the problem of blocking the device. After trying each of them, you will most likely unlock the device and be able to use all its functions.
How to unlock the tablet. Recovery methods
1. First of all, you need to apply the simplest methods if the tablet is blocked. Enter random numbers, letters - the system, of course, will answer in the negative. After several unsuccessful attempts to log in to the system, Android will prompt you to enter your authentication data (login and password) from your Google account ( Account Google).
Perhaps this is the most elementary way to unlock your "pocket computer", however, in practice, this will not work on all tablet models. And still try to enter the login (your Email without the "dog" and gmail.com) and the password from the Google mailbox. In case you do not remember this data, try to restore it through by going to the Google website.
2. Well, if you took care to make a backup in advance - a backup copy of the firmware. In this case, if the tablet (Samsung, Acer, etc.) is blocked, but it is equipped with a data recovery mode (recovery), then you can simply roll back to the backup.
3. The next method is to restore access to the system using proprietary programs. As a rule, such programs are bundled with branded tablet models like Asus, Samsung (Kies program), Lenovo or Acer. What else applications are useful for is that they allow you to “remember” the name of an email box on Google - the functions built into the program will display all the necessary data.
4. A rather tricky method, but not at all a fact that it will work on later models of tablets, and also not all tablets have the ability to insert a SIM card. The bottom line is that you need to call the SIM card number, and during the call go to the "Settings" menu and unlock. This method is more applicable for Samsung, HTC smartphones, etc.
5. If the above methods did not help unlock the tablet, and you do not know what to do already, do not despair. There is a way out, and it is called hard reset (full reset). But be aware that all data stored in the tablet's memory will be permanently deleted. Only those files that are on the memory card will remain.
How to make a hard reset on the example of Samsung Galaxy Note, if the tablet is blocked: hold down the volume buttons up, home (home) and the power button of the tablet at the same time, then release the last one. A menu will appear where you need to select "Wipe data / factory reset", and then "Yes - delete all user data", confirming by pressing "Home".
