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.

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This is only one of the first methods that work with outdated OSs.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.

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.

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.

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.

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:

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.

I hope our tips helped you. Try the universal algorithm described above. See you on the pages of the site!

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,

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.

Factory reset

So, if none of the above methods helped to unlock the tablet screen, then there are two options left - flashing the device and resetting it to factory settings.

Important! Regarding flashing, it is important to understand that this option can completely “kill” the tablet, and to implement it you need a whole set of tools, from the firmware itself, downloaded from the official website, to special software, which differs depending on the manufacturer.

This text will not describe the procedure, as it varies for each individual brand. To safely flash a tablet, you need to at least see how it’s done, since even the best description will not help in such a situation, and it’s even better to do it with a person who has previously done this. If you have no experience in flashing a device’s firmware, and there is no user nearby who is savvy in this matter, then the best option is to turn to specialists. Some manufacturers, such as Oysters, Irbis, Dexp and other little-known companies, are quite difficult to sew, and they do not have high-quality firmware, and using options written by non-specialists is quite dangerous.

For this reason, the last resort option, which is worth trying yourself, is to roll back the device to its factory state. This is done through Recovery; how to enter it was described above. After the user is in the system menu, he is interested in the “Recovery” item and the next item “Wipe data/factory reset”. The device will completely delete all user data and, accordingly, settings created by the owner, and after rebooting the device will need to be configured again, as if it had just been purchased.

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.

How to remove password from Android

There are different reasons why you may need to remove the screen lock password, but common sense says that this function is purely marketing.

What is the password for?

Judge for yourself, how many times has your push-button telephone fallen into the hands of criminals? But there was no screen lock, and no passwords were required to view information. Why is this important now? Do you deliberately leave your smartphone anywhere, do you constantly lose it, do you let the yard boys play with it? Where is the situation when I set a password for myself on the device itself?

You can understand office computers when everyone has their own account and their own password, but the smartphone is only yours, and you never part with it, why create a situation where in order to make a call you need to scan your fingerprint or enter a pattern? In general, everyone has their own reasons, and you just need to disable the password request.

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.

Google login for older Samsung devices (Android 4.4 or lower)

Old Samsung devices have the ability to bypass the lock if you have forgotten the access code to your gadget.

If you are the owner of a device based on Android OS 4.4 or earlier versions of Android, then do the following:

1. Go to the password entry screen;
2. Enter the wrong code five times;
3. After this, the message “Forgot your password?” will appear;

Click on “Forgot your password?”

1. Log in to your Google account or enter your backup PIN code;
2. Your Samsung phone will be unlocked.

What to do to unlock a tablet on Android OS
