Forgot the pattern key on the Lenovo tablet: all unlocking methods

Forgetting the pattern key for your tablet Lenovo is an unpleasant situation, but not a hopeless one. Even if you entered the wrong pattern several times in a row, and the device locked with a message or even prompted you to enter data, there are several ways to regain access. The main thing is not to panic and not try to guess the combination at random: after 20-30 unsuccessful attempts, many models "Try again in 30 seconds" or even asked to enter data Google account, there are several ways to regain access. The main thing is not to panic and not try to guess the combination at random: after 20–30 unsuccessful attempts, many models Lenovo automatically perform a factory reset, which will lead to the loss of all data.

In this article we will look at 7 working methods unlocking - from the simplest (via Google account or call) to radical (reset via Recovery Mode or ADB). Please note: the effectiveness of the method depends on the version Android, tablet model (for example, Lenovo Tab M10, P11 Pro or Yoga Smart Tab) and whether the functions "Find device" or "USB debugging"were enabled. If you are not sure about the model, look at it on the box or in the documents - this will help you choose the best option.

We warn you in advance: some methods require connecting to a PC, installing special apps, or even disassembling the device. If you have never worked with ADB or Fastboot, it is better to contact a service center - especially if important data is stored on the tablet. But if you’re ready to act on your own, let’s get started!

1. Unlocking via Google account (for Android 4.4 and below)

This is the simplest method, but it works only on older versions of Android (up to 5.0 Lollipop inclusive). If your Lenovo Released before 2015 (for example, Lenovo Tab 2 A10 or Yoga Tablet 2), try the following:

1. After 5 unsuccessful attempts to enter the pattern, the screen will appear button "Forgot your pattern key?" or «Forgot pattern?». Click on it.
2. The system will prompt you to enter the login and password for Google accountthat was linked to the tablet. Use the same data as for Play Market.
3. If authorization is successful, you will be redirected to the screen for creating a new pattern key. Design and confirm a new pattern.

⚠️ Attention: On tablets with Android 6.0+ this method will not work - Google has removed this option due to security vulnerabilities. Also, the method is useless if:

• 🔄 The device was reset to factory settings after purchase (the account is not linked).
• 📧 You do not remember your Google password or it was changed after setting up the tablet.
• 🔒 Two-factor authentication is enabled on the device (a code from SMS is required).

If there is no button, but you are sure that the tablet is "Forgot your pattern key?" no, but are you sure it's on a tablet? Android 4.4 or lower, try entering the key at random 10-15 times in a row. Sometimes the system still offers the option of recovery via Google. But be careful: on some firmware Lenovo after 20 unsuccessful attempts, automatic Hard Reset.

2 occurs. Using the “Find My Device” function

If your Lenovo is enabled geolocation services and remote control via Google, you can unlock the tablet remotely. This method works on any version Android, but requires:

• 🌐 Connecting the tablet to the Internet (via Wi-Fi or mobile network).
• 🔄 Linked and active Google account.
• 📍 Enabled function "Find device" in the settings.

Instructions:

1. On another device (smartphone, PC), open the browser and go to the website Find My Device (or enter in the search "Find Google device").
2. Login using the same account as on the locked tablet.
3. Select yours in the list of devices Lenovo. If it is not there, refresh the page or check if the Internet is turned on on the tablet.
4. Click "Lock" («Lock»).
5. Enter a new password (you can have a temporary one, for example, 123456) and confirm.
6. A field for entering this password will appear on the tablet. After successful unlocking, go to Settings → Security and change the pattern.

⚠️ Attention: If the tablet is not connected to the network, the blocking command will be executed only after the Internet appears. Also note that after unlocking in this way, you may need to re-authorize in some applications (for example, WhatsApp or banking services).

3. Unlocking via call (for Android 5.0–7.1)

This life hack works on tablets Lenovo s Android 5.0–7.1 (for example, Lenovo Tab 3 or Phab 2) and is based on a vulnerability in the processing of incoming messages calls. The essence of the method: during a call, you can access the device interface by bypassing the lock screen.

Step-by-step guide:

1. Call a locked tablet from another phone. If it does not have a SIM card, skip this step - the method will not work.
2. Accept the call on the tablet, but do not end the call.
3. During a call, quickly press the button "Home" (or swipe up if you have touch navigation).
4. If everything worked out, you will find yourself on the main screen. Without closing the call, go to Settings → Security and disable the pattern.
5. End the call and restart the tablet.

🔴 Method limitations:

• 📞 Does not work on Android 8.0+ —Google has closed this vulnerability.
• 🚫 If the tablet has a PIN code or password instead of a pattern, you will not be able to bypass the lock.
• 🔕 On some firmware Lenovo after the call ends, the lock screen returns.

If this method does not work, do not despair - in the following sections we will look at more reliable options, including working with ADB i Recovery Mode.

4. Resetting the pattern key via ADB (for users with USB debugging)

The method is suitable if the tablet USB debugging is enabled (USB Debugging) has access to a computer. This is one of the most effective methods, as it does not require resetting data. However, it is technically more complex than the previous ones - you will need to install Android SDK or a minimum package ADB.

What you need to do:

1. Download and install on PC Android Studio (full version) or minimum ADB package (for Windows, macOS or Linux).
2. Connect the locked tablet to the computer via a USB cable.
3. Open the command line (cmd on Windows or Terminal on macOS/Linux) and go to the folder with ADB (for example, cd C:\platform-tools).
4. Enter the command to check the connection:

   adb devices

   If the tablet is detected (its serial number will appear), continue. If not, install drivers for Lenovo or try a different cable.

5. Run the command to delete the file with the pattern:

   adb shell rm /data/system/gesture.key

   or for new versions of Android:

   adb shell rm /data/system/locksettings.db
   adb shell rm /data/system/locksettings.db-wal
   adb shell rm /data/system/locksettings.db-shm

6. Reboot the tablet with the command:

   adb reboot

After the reboot, the pattern will be reset and you can set a new one. If the command rm did not work, try an alternative:

adb shell
su
cd /data/data/com.android.providers.settings/databases
sqlite3 settings.db
update system set value=0 where name='lock_pattern_autolock';
update system set value=0 where name='lockscreen.lockedoutpermanently';
.quit
exit
exit

⚠️ Attention: If USB debugging was not enabled before the lock, this method will not work. Also on some models Lenovo (for example, Tab M8) it may be necessary to root permission. voids the warranty.

5. Hard Reset via Recovery Mode (full reset)
