How to Bypass Google Lock (FRP) on Samsung Devices: Working Methods for All Android Versions

If you have recently factory reset your Samsung Galaxy device because it was lagging, soft-bricked, or because you forgot your lock screen passcode, you may have run headfirst into a screen reading: "Verify your account. This device was reset. To continue, sign in with a Google Account that was previously synced on this device."

This security mechanism is called FRP (Factory Reset Protection), or Google Lock. While FRP is a stellar feature for preventing thieves from using stolen phones, it is a massive headache for legitimate owners who bought secondhand devices, forgot old Gmail credentials, or are managing older business hardware fleets.

What Exactly is Factory Reset Protection (FRP)?

Introduced by Google in Android 5.1 (Lollipop), FRP is automatically enabled the moment a Google Account is registered on a device. If a phone is reset through recovery mode or recovery hardware keys (button combinations) rather than the official Settings application, Android locks the device down until the original Google password is provided.

Method 1: The Emergency Dialer "No-PC" Bypass Code (*#0*#)

This is currently the fastest, most effective bench method for Samsung flagships running older to mid-level security patch levels. It leverages Samsung's hardware test menu to force USB Debugging authorizations.

1. Power on your locked Samsung device and return to the primary Welcome/Setup Wizard screen.
2. Tap on the Emergency Call button at the bottom of the screen.
3. In the dialer pad, dial: *#0*#
4. Samsung's official hardware diagnostic screen (a grid of white tiles) should instantly appear. If this menu does not pop up, your current security patch has patched this backdoor—proceed to Method 2.
5. If the diagnostic screen opens, connect the phone to your PC using a high-quality USB-C cable.
6. Open a safe diagnostic utility (such as the SamFw Tool) on your PC and click on Remove FRP.
7. Watch the phone's display. You will see a pop-up prompt asking to "Allow USB Debugging". Tick "Always allow" and tap Allow.
8. The PC program will bypass the setup screen and automatically reboot your device into the home screen.

Method 2: Flashing and Bypassing with SamFw Tool (PC Required)

For newer security patches where the emergency dialer screen is disabled, you must use a PC-based program to communicate with the phone’s bootloader interface.

• Step 1: Download and install the latest official Samsung USB Mobile Drivers on your Windows PC. This prevents data packet drops during the bypass.
• Step 2: Download the official SamFw Tool (ensure you only download it from verified developer sources like samfw.com—never download from unverified file mirrors).
• Step 3: Launch the tool, connect your device, and select the Samsung tab.
• Step 4: Select the version year corresponding to your phone's security patch and click Remove FRP [New Method].
• Step 5: Allow the software to send the exploitation commands. Keep your phone connected and still until the device restarts.

How to Prevent FRP Lock on Secondhand Devices

If you are preparing to sell your Samsung phone or are buying a used device from platforms like Facebook Marketplace or eBay, always verify the following before completing the transaction:

1. Open Settings > Accounts and Backup > Manage Accounts.
2. Tap on your Google Account and select Remove Account. Confirm this step.
3. Do the same for your Samsung Account.
4. Once all linked accounts are completely removed, perform a factory reset through Settings > General Management > Reset > Factory Data Reset.

Device Disassembly & Hardware Diagnostic References

If you suspect the USB port on your device is damaged (which prevents the PC tool from recognizing your phone), you must first clean or replace the port. Below is an official hardware disassembly and diagnostics structure to help you inspect the inner connectors safely:
