Removing Google Account Lock on Android 16 Security Patches

The Samsung Galaxy S25 Ultra is a powerhouse, but its security is equally formidable. With the integration of Android 16 and the latest Knox Vault 4.0, bypassing Factory Reset Protection (FRP) on this device requires professional-grade tools and updated methodologies. As an engineer with 12 years of experience, I have developed a foolproof routine for this specific model.

Device Specifications & Security Context

Model Number	SM-S938B, SM-S938U, SM-S938N
Chipset	Snapdragon 8 Gen 4 (For Galaxy)
Security Patch	January 2026 / February 2026
Bypass Method	MTP Test Mode (*#0*#) or EDL Mode (9008)

Important: Ensure your phone has at least 50% battery. A sudden shutdown during the FRP erase process can lead to a soft-brick or "Emergency Software Recovery" mode.

Primary Method: Test Mode (*#0*#)

This is the fastest method for the S25 Ultra. It utilizes the hidden hardware diagnostic menu to trigger the ADB (Android Debug Bridge) command.

Step-by-Step Procedure:

1. Power on your S25 Ultra and reach the Welcome Screen.
2. Tap on Emergency Call and dial *#0*#. A white diagnostic screen will appear.
3. Connect your phone to your PC using a high-quality USB-C cable. Ensure you have the Samsung USB Drivers installed.
4. Open the SamFw FRP Tool on your desktop.
5. Click on the "Remove FRP" button. Watch your phone screen carefully.
6. A prompt asking to "Allow USB Debugging" will appear. Check the box "Always allow" and tap OK.
7. The tool will execute the bypass. The phone will automatically reboot, and you will bypass the Google lock.

Secondary Method: EDL Mode (For US Models)

If you are using a US variant (Verizon, AT&T, T-Mobile), the *#0*# code might be disabled. In this case, you must use the EDL (Emergency Download) Mode.

For this method, you will need the Unlock Tool. You must short the test points (as shown in Figure 2) and connect the device to your PC. The tool will detect it as Qualcomm HS-USB QDLoader 9008 and allow for a 1-click FRP erase.

Common Issues and Troubleshooting

• "MTP Device Not Recognized": This is usually a driver issue. Try using a different USB port (preferably USB 2.0) or update your ADB Drivers.
• *#0*# Not Working: If the code doesn't open the menu, your security patch is likely too new for this method. You will need to wait for a software update in your Z3X Tool or use a paid online service.
• FRP returns after reset: Make sure to go to Settings > Accounts and add your own Google Account immediately after the bypass.

Conclusion

Bypassing the FRP on a flagship like the Samsung Galaxy S25 Ultra requires patience and the right professional tools. Whether you are using the SamFw method or the advanced EDL routine, following these steps accurately will ensure a 100% success rate in 2026.
