How to remove a password from an Android tablet if you forgot the combination: all working methods

Forgotten password on a tablet Android is a situation that every fifth user faces. According to statistics from service centers, 18% of requests for device blocking are related specifically to lost graphic keys or PIN codes. The problem is aggravated by the fact that modern tablets (Samsung Galaxy Tab, Lenovo Tab, Xiaomi Pad etc.) use enhanced security measures, and manufacturers deliberately make it difficult to bypass the lock to prevent unauthorized access.

In this article we will look at all current unlocking methods - from the official ones (via Google account or Find My Device) to technical (using ADB or recovery mode). Important: not all methods are suitable for new versions Android 12+where manufacturers have introduced additional barriers. We will separately note which solutions work for Android 10/11, and which ones only for old firmware.

Before you begin, check:

• 🔄 Do you have a backup copy of your data? (Resetting settings will delete everything from the device)
• 📧 Is an account linked to the tablet Google or Samsung?
• 🔌 Is the device charged at least 30%? (Discharge during the procedure can lead to “scaling”)

1. Unlocking via Google account (only for Android 4.4–9.0)

This method worked on versions Android to 10th inclusive, but in new firmware manufacturers removed the ability to bypass via Google account for security reasons. If your tablet was released before 2019, try the following:

1. Enter any password/key 5 times in a row until the message appears "The device is locked, try again in 30 seconds".
2. A button will appear at the bottom of the screen "Forgot your pattern key?" or "Forgot your password?" - click on it.
3. Enter your login and password from Google accountthat was linked to the device.
4. Create a new pattern or PIN code.

⚠️ Attention: On Android 10+ this method will not work - instead of the restore button, a notification will appear indicating the need to reset to factory settings. Also, the method is not suitable for tablets with data encryption (enabled in the security settings).

Why did Google remove this function?

In 2019, security researchers discovered a vulnerability that allows you to bypass blocking through substitution of authentication servers. Google and device manufacturers have since removed the "Forgot your password?" option. from the unlock interface.

2. Using the Find My Device service (for tablets with a Google account)

If the function is enabled on your tablet (and it is enabled by default on most devices), you can reset your password remotely via the web interface. This method works on "Find device" (and it is enabled by default on most devices), you can reset your password remotely via the web interface. This method works on Android 5.0+, but requires:

• 📶 Connecting the tablet to the Internet (via Wi-Fi or mobile network)
• 🔄 Enabled synchronization with Google account
• 📍 Access to another device (PC, smartphone) to log into the service

Step-by-step guide:

1. Go to the site google.com/android/find from another device and log in using the same account as on tablet.
2. In the list of devices, select a locked tablet.
3. Click "Lock" (yes, blocking is not a typo!).
4. Enter new temporary password (for example, 12345678) and confirm.
5. A field will appear on the tablet to enter this password - use it to unlock.
6. After logging in, immediately go to Settings → Security and set a permanent password.

⚠️ Attention: If the tablet has been turned off or not connected to the network for more than 72 hours, the lock command may not work. In this case, the service will only offer "Erase data", which will lead to a complete reset.

3. Factory reset via Recovery Mode

This is the most reliable methodbut it completely deletes all data from the device, including photos, applications and settings. Use it if other methods have not helped or you do not have an attached one Google account.

How to enter Recovery Mode:

• 🔄 Turn off the tablet (press and hold the power button for 10-15 seconds).
• 🔧 Press the button combination:
  • For Samsung: Power + Volume up + Home (if there is a physical button)
  • For Lenovo/Xiaomi/Huawei: Power + Volume up
  • For Asus/Google Pixel: Power + Volume Down, then select from the menu Recovery Mode
• 🖥️ Hold the buttons until the brand logo appears, then release.

In the menu Recovery use the volume buttons to navigate and the power button to choice. Next:

1. Select Wipe data/factory reset (on some devices - Clear eMMC).
2. Confirm the action (Yes — Delete all user data).
3. After reset, select Reboot system now.

Make sure the tablet is charged 50%+

Download drivers for your model (if you need to connect to a PC)

Prepare a backup copy of important data (if you have access to the cloud)

Write down the IMEI of the device (on the box or under the battery) in case of problems with activation after a reset

⚠️ Attention: On tablets c Android 8.0+ after the reset, you may need to enter data from Google accountthat was linked earlier (FRP blocking). data-i="137">Google account bypassing FRP through special utilities (for example, FRP Hijacker or SamFw Tool), but this is a topic for a separate article..

4. Unlocking via ADB (only if USB debugging is enabled)

The method is suitable for advanced users and requires that the tablet has USB debugging is enabled (Settings → For developers → USB debugging). If you have not activated this function in advance, the method will not work.

What you will need:

• 🖥️ Computer with installed drivers for your tablet
• 🔌 USB cable (preferably original)
• 🛠️ Utility ADB (download from the official website Android Developers)

Instructions:

1. Connect the tablet to the PC via USB.
2. Open the command line (Win + R → cmd) and enter:

   adb devices

   The device should appear in the list.

3. Enter the commands one by one:

   adb shell
   su
   rm /data/system/gesture.key

   For the PIN code, use:

   rm /data/system/password.key

4. Reboot the tablet:

   reboot

After reboot, the password will be reset, but you may need to set a new one.

⚠️ Attention: On Android 9.0+ this method often does not work due to changes in the security key storage system. Also, some manufacturers (for example, Huawei) block access to su even with debugging enabled.

5. Bypassing the lock via Safe Mode (if a third-party application is at fault)

Sometimes the tablet is blocked not because of a forgotten password, but because of a malfunction. third-party launcher or blocker applications (for example, AppLock or Norton App Lock) In this case, safe mode (Safe Modewill help, which disables all user apps.

How to enter Safe Mode:

1. Turn off the tablet.
2. Turn it on by holding the button Volume down until the logo appears.
3. Release the button when the message appears at the bottom of the screen "Safe Mode".

In safe mode:

• Uninstall suspicious applications through Settings → Applications.
• Reset the screen lock password (if this was caused by a launcher failure).
• Restart the tablet in normal mode.

If the problem disappeared, third-party software was to blame. If not, move on to other methods.

6. Contacting the service center: when this is the only option

If none of the above methods help, there are two options left:

1. Official service center — they will unblock it in 1-3 days, but will require proof of purchase (receipt, warranty card) or linked account information.
2. Unofficial workshops —they can bypass the blocking through EDL mode or flashing, but this is risky (possible loss of IMEI or “skipping”).

Cost unlocking in 2026:

Type of service	Term	Cost (₽)	Risks
Official service (with guarantee)	1–3 days	1 500–4 000	Minimum (warranty maintained)
Unofficial workshop (without warranty)	1–2 hours	800–2 500	Possible data loss, IMEI, account blocking
Independent flashing	30–120 min	0 (free)	High risk of “bricking”

⚠️ Attention: On tablets Samsung with Knox (corporate protection), independent flashing can lead to irreversible bootloader lock. Check the status Knox through the download mode: if it says KNOX WARRANTY VOID: 0x1the device has already been hacked and the official service will refuse warranty.

Frequently asked questions (FAQ)

Is it possible to unlock a tablet without losing data?

Theoretically, yes, but only if:

• The device is enabled USB debugging (method with ADB).
• You have a backup copy in Google Drive or Samsung Cloud.
• The tablet works on Android 5.0–7.0 (you can try bypassing through gesture.key).

On Android 10+ without data loss, unlocking is almost impossible due to storage encryption.

Why After resetting, the tablet requires the old Google account?

This is FRP blocking (Factory Reset Protection, which appeared in Android 5.1. It links the device with the account that was on it before the reset. You can bypass it:

• Through Find My Device (if you remember your account details).
• Using special utilities (FRP Bypass APK, but requires USB-OTG).
• At the service center (proof of ownership will be required).

What to do if the tablet does not turn on after unsuccessful unlocking?

Symptoms of "bricking":

• Black screen when turned on.
• Continuous reboot (bootloop).
• Error "No Command" in Recovery Mode.

Solutions:

1. Try to go to Fastboot Mode (hold Power + Volume Down) and reflash the device via Odin (Samsung) or SP Flash Tool (for Mediatek).
2. If the tablet is not detected by the PC, you will need EDL mode (only for qualified technicians).

How to avoid blocking in the future?

Preventive measures:

• 🔐 Use fingerprint or face recognition as an additional unlocking method.
• 📝 Write down passwords in Google Password Manager or KeePass.
• 🔄 Create backups regularly via Settings → System → Backup.
• 📧 Link a spare email or phone number to your tablet for recovery.

Do unlocking apps work (for example, Dr.Fone)?

apps like Dr.Fone, iMyFone LockWiper or Tenorshare 4uKey can help, but:

• ✅ Not all models are supported (for example, they do not work with Samsung Knox).
• ⚠️ Require payment (from 1,000 to 5,000 ₽ for unlocking).
• 🚫 May contain malware (download only from official sites).

Before purchasing, check on the app website whether your tablet model is supported.
