Resetting Android settings to factory settings is a standard procedure when selling a smartphone, fixing system failures, or preparing the device for a new owner. However, many users encounter an unexpected problem: after a reset, the system requires entering data Google account, but does not accept the correct password, gives an authentication error, or completely blocks access. What is the reason and how to regain control of the device?

The problem is most often associated with the mechanism Factory Reset Protection (FRP) —reset protection, which Google introduced in Android 5.1 Lollipop and strengthened in subsequent versions. This feature links the device to the last used account to prevent data theft if the phone is lost. But sometimes FRP also works for legitimate owners, especially if:

  • 🔄 You reset the settings through Recovery Mode, and not from the system menu
  • 📱 The device was previously linked to another account (for example, after purchasing a used phone)
  • 🔒 Two-factor authentication is enabled on the account In this article Let's look at, but the backup codes are lost
  • 🕒 More than 72 hours have passed since the last synchronization with Google

In this article we will analyze 7 proven methods how to bypass the blocking, from official recovery methods to technical workarounds. Important: some solutions require access to a computer or additional devices.

📊 How often do you reset Android settings?
Never
Once a year
Only before sale
Frequently (once every 2-3 months)

1. Check that your account information is entered correctly

Let's start with the obvious: the error may lie in an incorrectly entered login or password. Android is case sensitive, spaces and special characters are sensitive. Make sure that:

  • 📧 The field Email includes the full address (including @gmail.com or another domain)
  • 🔐 The password is entered taking into account capital letters and symbols (for example, P@ssw0rd ≠ p@ssw0rd)
  • 🌐 The keyboard has been translated into the desired language (English layout for Latin characters)

If you have forgotten your password, use the recovery function on the page accounts.google.comPlease note: after changing the password, it may take up to 24 hoursfor the changes to take effect on all devices.

⚠️ Attention: If you bought the phone second-hand and the previous owner did not delete your account, it is impossible to restore access without his data. In this case, contact the seller for your login and password or use the methods from section 5.
💡

If the keyboard is not displayed on the lock screen, connect a USB keyboard via OTG adapter. This will help you enter the data more accurately.

2. Use backup codes or two-factor authentication

If your account is enabled 2FA (two-factor). authentication), the system will require not only a password, but also a confirmation code. Here's how to get it without access to the phone:

  1. Go to the page Google security management from another device.
  2. In the section Two-step authentication find Backup codes.
  3. Use one of the unused codes to log in on a locked device.

If the backup codes are lost, request an SMS or call to the linked phone number. An alternative option is confirmation through the app Google Authenticator (if installed). on another device).

Confirmation method Code validity period Internet required
SMS 5 minutes No
Call 1 minute No
Google Authenticator 30 seconds Yes (for synchronization)
Backup codes Before use No

Critical detail: if mobile data or Wi-Fi is disabled on the device, you will not be able to request an SMS code. In this case, connect to the network through the emergency call menu (available on some models to bypass the blocking).

3. Bypass FRP through Wi-Fi settings (for Android 8-11)

On devices from Android 8 Oreo to Android 11 there is a vulnerability that allows you to bypass FRP through the Wi-Fi connection menu. Instructions:

1. On the account login screen, click "Add Wi-Fi network"|2. Enter any network name (for example, "123") and press "Save"|3. input field until the "Share" menu appears|4. Select "Settings" → "Account Management"|5. Delete all Google accounts and restart the device-->

After reboot, the system will offer to set up the device as new. This method does not work on all models - manufacturers (for example, Samsung or Xiaomi) often close such loopholes in their shells.

⚠️ Attention: This method does not work due to stricter security policies. For new versions, use the methods from sections 5 or 6. Android 12+ this method does not work due to stricter security policies. For new versions, use the methods from sections 5 or 6.

4. Recovery and Fastboot

If software methods do not help, try resetting FRP through service modes. To do this, you will need a computer with installed drivers ADB and Fastboot.

Instructions for Samsung (similar for other brands adjusted for firmware):

  1. Turn off the device and hold Volume up + Power + Home (for new models - Volume up + Bixby + Power).
  2. In the menu Recovery select Wipe data/factory reset (use the volume buttons to navigate).
  3. After the reset, connect the phone to the PC and enter the commands: 
    adb shell

    content insert --uri content://settings/secure --bind name:s:user_setup_complete --bind value:s:1

  4. Reboot the device (reboot system now).

For devices Xiaomi or Huawei you may need to flash custom firmware recovery (for example, TWRP) followed by deleting files /data/system/gesture.key and /data/system/locksettings.db.

What to do if ADB does not see device?

Make sure that:

1. USB debugging mode is enabled (this cannot be done on a locked device - you will need to unlock it in another way).

2. Drivers for your model are installed (download from the manufacturer’s official website).

3. An original USB cable is used (cheap cables often do not support data transfer).

If the device is still not detected, try another USB port or computer.

5. Deleting an account through service codes (for some models)

Some manufacturers leave "service" codes. loopholes" to reset the FRP. For example, on phones Samsung you can use the combination:

  1. On the login screen, enter any email and password 5 times in a row until a message about blocking appears.
  2. Click Forgot your password? and enter the service code: ##4636##.
  3. In the menu that opens, select Usage statistics → Back → Settings.
  4. Go to Accounts and delete all Google profiles.

For LG the code 277634#*#is suitable, after entering it the menu will open Hidden Service Menu. Next select Factory Reset → FRP Reset.

⚠️ Attention: Service codes may vary depending on the region and firmware version. Entering the code incorrectly may cause the system to crash.

6. Contacting Google support

If all independent attempts are unsuccessful, contact official Google support:

  1. Go to page account help.
  2. Select section Login problems → Device locked after reset.
  3. Fill out the form indicating the IMEI of the device (you can find it on the box or under the battery) and proof of ownership (receipts, warranty cards).

The period for consideration of the request is from 3 to 7 days. If the decision is positive, Google will send unlocking instructions to the backup email. Please note that support may refuse if:

  • 📄 You do not have documents confirming the purchase
  • 🔄 The device was purchased secondhand without transferring rights to the account
  • 🚫 The phone has unofficial firmware installed

7. Extreme measures: flashing the device

If none of the methods worked, a radical solution remains - completely flashing the phone. This will delete all data, including the FRP lock, but will require:

  • 💻 A computer with a firmware app (Odin for Samsung, SP Flash Tool for MediaTek, etc.)
  • 📄 Official firmware for your model (download only from trusted sources, for example samfw.com for Samsung)
  • 🔌 USB cable with data transfer support

Step-by-step guide for Samsung:

  1. Download the firmware in format .tar.md5.
  2. Run Odin in administrator mode.
  3. Connect your phone in mode Download Mode (press Volume Down + Power + Home).
  4. V Odin select the firmware in the field AP and click Start.

For devices on a chip Qualcomm (for example, OnePlus, Xiaomi) use QFil or EDL Mode. The flashing process takes 5-10 minutes, after which the phone will start up like new.

💡

Flashing deletes all data without the possibility of recovery. Use this method only if other options have been exhausted.

FAQ: Frequently asked questions about blocking Google after a reset

You can Is it possible to bypass FRP without a computer?

Yes, but only on older versions of Android (up to 9 inclusive). On new devices without a PC, bypass is unlikely due to tightened security. Try the Wi-Fi method (section 3) or service codes (section 5).
