How to unlock an Android tablet if you forgot your password

Such blocking, although convenient, can cause problems. The most common one is what to do if you forgot your pattern key?

ADB unlocking occurs by connecting the device to a computer and involves changing the code in the software part of the device. This is a complex and very unreliable option, since if the character is entered incorrectly, the entire system can be damaged, so I do not recommend using it.

Options for protecting personal data on tablets

Through a special system recovery menu, also called recovery, you can reset the settings to factory settings.

Fortunately, there are several effective ways to unlock Android, each of which has its own nuances. All methods on how to disable the pattern are described in detail below.

To reset all data, you need to go to Settings and select the item of the same name. It is named differently on different devices. After the procedure is completed, the gadget will be reset, which means that all user data on it will be deleted.

As soon as we have connected the tablet to the computer, we need to open the command line through “Start”. There we find the “Run” section and in the line that opens, enter: “cmd”. A line appears on a dark screen in which you need to specify the path to the pre-downloaded ADB application. Next, the user needs to enter the following commands one by one. One of them should give a positive result.

To use this method you need to do a few simple steps:

Once the mode is activated, information will appear in English. To switch between categories, use the volume rocker. And to go to a certain menu item you need to use the power key. As a result, we need to find the Wipe data section. We confirm everything until the settings are completely reset and updated.

Hardware Hart Reset

Hart Reset is a complete hard system wipe of the operating system, deleting all information and returning to factory settings. All data about the user is completely deleted: browsing history, phone book and call log, cache and everything else. It is impossible to restore information after cleaning. There are two ways to unlock a Huawei tablet by performing a Hardware Hart Reset.

Method 1

The first method is similar to a regular factory reset. First you need to turn off the gadget. Then hold down the volume and power keys. After turning on the screen, select “wipe data/factory setting” and activate the action by clicking on “Yes-delete all data”. After a long cleaning, reboot the tablet by clicking “Reboot”. After rebooting, the gadget will be the same as from the store.

Method 2

This method involves pressing the buttons sequentially in the correct order. Perform actions with the device turned off.

1. Press the volume and power buttons at the same time;
2. After the screen lights up, release the power button and leave the volume buttons on;
3. A green robot will appear on the screen, after that, release part of the “Volume Plus” button and leave only “Volume Minus” pressed;
4. This should cause a green stripe to appear under the robot. If this happens, the procedure is completed.

The above methods for unlocking the screen in such a situation should help you cope with the task. If for some reason it still doesn’t work out for you, contact the service center for specialist help.

Unlocking via ADB app

Suitable for those who remember and have their own Google account. Using it, you can get a new password and open access to the device without losing stored information.

You can block your device in the following ways:

This is only one of the first methods that work with outdated OSs. If the device does not have a SIM card, then you can try other flaws in the system, which are widely written about on the Internet.

This option will tell you how to unlock your tablet if you have forgotten the password for an Android device of any version. But even here there are limitations, that is, mandatory conditions for using the method. To remove a block using this method, the following factors must be present:

To work, you will need to connect your phone to your computer using a USB cable. Instructions for working with this utility are as follows:

update system set value=0 where name='lock_pattern_autolock';

All more or less large and well-known electronics manufacturers have their own websites with working technical customer support. It often happens that technical support specialists can tell you how to reset or recover the password on your tablet without resorting to radical measures, such as resetting the settings.

Reflash the device

If the user was unable to enter the Recovery menu, then all that remains is to reflash the device, since this is the only way to start operating it from scratch. For flashing you will need :

1. Find the required firmware version for the device (firmware is selected depending on the manufacturer).
2. Now, on the official website you need to download the necessary software to control the tablet system.
3. Next, you need to connect the device to a personal computer and launch the previously downloaded software. It will automatically detect the user's device and offer to start OS updates.
4. After which, the firmware begins to download and install on the tablet.

Method 2: Contact technical support

Consider contacting Samsung technical support through their official website:

This method is universal and suitable for all devices running Android OS (and not only Android). However, you should resort to it only as a last resort and only as a last resort, since all user data will be deleted along with the password. Most deleted data cannot be recovered.

The average waiting time for a response from technical support can vary from several hours to a day. Usually, for large manufacturers, support works quite quickly and the answer comes in less than an hour.

1. Turn on your device so the lock screen appears.
2. Find on it the inscription or button “Forgot your password?”. It can usually be found at the bottom of the lock screen. Sometimes it may be called “Remember password”, “Recover password”, etc. Click on it.

Often, when setting up a tablet for the first time, users simply scroll through the suggested items, and this is a mistake, since among them there are useful utilities that will help unlock the tablet in the future.

If the owner has forgotten the graphic password, then there is a way out. The first thing that comes to mind is to roll back the device to factory settings, but this will delete all data, so this option should be used as a last resort. It is much easier to use a Google account if the device is controlled by the Android OS.

Recovery via SIM

After installation, the software turns on automatically. In software settings, you should activate the “Automount all devices on start” mode.

Another way to unlock a password on a tablet is to use the ADB computer utility. This method only works if USB debugging is enabled on the device. We go to the PC in ADB RUN, first connect the tablet to the laptop and make sure that the latter sees it. We go through two menu items: Reboot – Reboot Recovery. The application resets the tablet settings and removes the lock password.

The first option will help if Smart Lock is configured on your device. It has three unlocking options:

Of course, it is possible to remove passwords from a tablet. There are several techniques that will be discussed further. But, if they do not work, you will have to use more radical methods, for example, a hard reset, that is, a complete hardware reset and hard cleaning of the system.

You can use this utility to manage or troubleshoot your device. And in an emergency, such as losing a key, for example, this tool is perfect. To use it, you need access to a computer or laptop running Windows, a USB cable, and the debug mode installed on the device itself. The program must be downloaded and installed on your computer. On a locked gadget, the main settings menu is, of course, inaccessible, but debugging mode can be connected directly via the USB port.

There are two types of such locks:

If the user has a Google account, then he can easily access the device without losing personal data. You just need to enter the required username and password.

You can download Android Debug Bridge (adb) here

The password is specified in text, which consists of a random set of numbers (sometimes letters). The correct combination unlocks the tablet. This method is quite popular among users, as it does not present any particular difficulties; Graphic drawing. Many people prefer to block their personal tablet this way.

The disadvantage of this algorithm is the lack of backup copies, as a result of which all user data will be destroyed. But the iPad will work great.

Using a graphic key. Any tablet can be connected to a desktop PC via a USB cable. Below is the sequence of actions performed when using a graphic key:

For each device from a particular manufacturer’s product line, the unlocking sequence is standardized. In this situation, you can start unlocking only if you have additional storage of information about the gadget and provided that this iPad was previously synchronized with iTunes. Only in this case can resuscitation be carried out with normal recovery. This is done like this:

Can a tablet be permanently locked?

In some equipment, for example, in Prestigio brand devices, a reset occurs by pressing the power, volume and Home buttons. If one of these keys is missing, then you need to look in the instructions for other reset methods.

A good way to unlock is to “bring the tablet up to condition.” To do this, when loading it, you need to constantly and continuously dial the key. Sooner or later, the computer will get tired of this, and the display will prompt you to enter your Google account or Apple Store account information. Then, having gained access to the system, the user will be able to change the security method and code.

Many lovers of new products can find an Alcatel tablet. In general, the unlocking algorithm is similar to the recovery sequences of other models. For example, when starting to use Google, the user must create his own account. After entering the pattern key incorrectly several times, a message about logging into your account and resetting the key will appear on the screen.

Reference! There is no such thing as tablets being blocked forever. You can always find a way to unlock it. You just need to know how. As a last resort, you can reflash the gadget.

If these methods for unlocking the tablet did not help you, then you can still try to reflash it, which is highly not recommended, since after reflashing the tablet, the warranty on it will immediately be voided,

Methods for resetting a pattern without losing data

One of the simplest methods is to repeatedly enter the wrong key. To do this you need:

1. enter the wrong pattern several times;
2. wait for the window with the Google account request form to appear;
3. Enter your login (mailbox) and password.

After this, your pattern will be reset. However, there is one thing - it is not always possible to check your account details, since there may be no Internet connection. In this case you need:

1. find an active Wi-Fi access point;
2. start the dialer by clicking “emergency call”;
3. enter the code to call the engineering menu in the dialer (for example *#*#7378423#*#*);
4. select Service tests - WLAN in the window that appears;
5. connect to the access point.

If for some reason this method does not suit you, you can use the active window method. To do this we do the following:

1. download and install the proprietary HiSuite utility;
2. connect your smartphone to your computer via a USB cable;
3. launch the utility and go to the “Contacts” section, and then “My e-mail”;
4. pull down the status bar curtain after the notification appears and go to system settings;
5. disable graphic key protection.

If there is no PC nearby or for some reason you cannot follow the instructions, you can wait until the battery drains and when a warning window appears, use the curtain to call up the settings.

If your device is rooted and has a custom recovery installed, you can try to delete the file with the pattern key data yourself. In this case, after rebooting, you can enter any gesture to unlock the device. To do this you need:

1. download Aroma File Manager and place it in the root of the memory card;
2. launch custom recovery;
3. flash the archive with the utility;
4. after Aroma File Manager starts, go to the “system root/data/system/” directory and delete the gesture.key file.

If there is no custom recovery on your device or can only be launched from the system, you can try your luck with stock recovery. To do this, you will need to flash the script to delete the pattern data file:

1. launch recovery (volume up + power button);
2. select the item “install .zip”, “install update.zip” (or the like, depending on the device);
3. select our archive and flash it.

That's all. If none of these methods help you, you will have to try extreme methods. If this does not suit you, you will have to contact an official service center.

Unlocking your tablet by restoring firm settings.

• After several incorrect attempts , the system will automatically display a message stating that the user is entering incorrect data and should restore access through their Google account. To do this, he will need to click on the dialog message that says: “ Forgot your password? "
• Next, all you have to do is enter your registration data (login or email, as well as password) and within a few minutes you will receive an email with detailed instructions for restoring access, where you can change the type of protection or completely remove the combination.

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.

We use Google accounts

For different devices and operating system versions, the installation of the pattern may be slightly different .

It is important to know : in some cases, trying to enter the security key can 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, troubles begin, especially if you need to use the tablet urgently. How to remove graphic keys will be discussed below.

As a rule, you can protect your data on a tablet in two ways - a pattern and a 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 using a password?

Keep your device with you and monitor the battery level at all times. As soon as a warning appears that the battery is low, go to the “battery status” menu. In the drop-down menu, sequentially click on the commands “settings” - “privacy” - “reset settings”.

When you forgot your password, don’t remember your email, and your account cannot be restored, you need to reset the tablet to factory settings.

Are you as forgetful as I am and can’t remember your Google account details? Let's try the following method to unlock the tablet through a computer or laptop by connecting a USB cable.

Third-party software and its capabilities

You can once again make sure that you need to register a Google account using unblocking utilities from the Internet.

Attention! This is the most radical way. This way you can access the tablet. In this case, all data from it will be lost irretrievably. If very important information is stored on the hard drive, it is better not to resort to such measures. Contact the service center or the nearest IT workshop. They will help you remove the wrong password and remove all files intact onto a hard drive.

What to do if you forgot the password for a device on the Windows operating system? First of all, it’s worth figuring out what type of record is blocked—local or account. You can recover your password using the online password recovery form on the official Microsoft website.

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

If you cannot unlock your tablet while connected to the Internet, you can try the following: when you enter the key incorrectly many times in a row (usually after the fifth time within 30 seconds), carefully watch the screen - a window will pop up asking you to restore access , and enter your username and password for your Google mailbox (gmail). In some cases, the offer to restore access will be at the bottom of the key entry field, like on the Nexus 7.

Judging by the statistics, many people have problems unlocking their tablet. Unfortunately, even if the device is under warranty, they will not unlock it for you for free. You'll have to pay some money, but you won't have to make any effort. Don’t want to spend money on paying at the service center? No problem, read on. In this article I will discuss restoring access to your device if you have forgotten your password or pattern to log in.
