Introduction: Why the S24 Ultra Remains a Challenge

The Samsung Galaxy S24 Ultra was the pioneer of AI-integrated mobile security. As we move through 2026, many of these devices are entering the secondary market or requiring professional refurbishing. However, the Factory Reset Protection (FRP) on this specific model is notoriously stubborn due to its integration with the Snapdragon 8 Gen 3 security architecture and the evolution of Android 16 (One UI 8.0).

Technicians often struggle with the S24 Ultra because it features multiple layers of defense: Knox Vault, real-time kernel protection, and encrypted bootloaders. But there is a silver lining. Despite these advancements, the legacy Diagnostic Port (Test Mode) remains accessible for hardware testing, which we will leverage to gain ADB access and remove the Google Lock permanently.

The Technical Architecture of Security in 2026

In 2026, Samsung's security has shifted from simple partition locking to behavioral analysis. Android 16 can detect if a system process is being manipulated. However, by using the *#0*# command, we suspend these high-level security monitors and enter a low-level diagnostic state. This is where the SamFw Tool excels by communicating directly with the device's serial interface.

Chipset: Snapdragon 8 Gen 3 / Exynos 2400

OS Compatibility: Android 14, 15, & 16

Method: ADB Service Exploit

Success Rate: 98.5% for Global Variants

Preparation: Setting Up Your Technician Workstation

Make sure your workstation recognizes the S24 Ultra correctly.

A failed bypass on an S24 Ultra is almost always a result of poor environmental setup. Follow these rigid prerequisites before connecting the device:

1. Reliable Connectivity: You must utilize a USB 3.1 Type-C cable. Generic charging cables do not have the necessary bandwidth for ADB handshakes. Ensure you have the Latest Samsung USB Drivers 2026 installed on your Windows 11 machine.

2. Environmental Cleanup: Disable any third-party antivirus software. Tools like SamFw are often flagged as "False Positives" because they interact with system kernels. To understand port behaviors better, read our Qualcomm 9008 Driver Configuration Guide.

Phase 1: The Core Bypass Procedure (2026 Optimized)

STEP 01

Triggering the Emergency Diagnostic Mode

Activating the hidden gateway for FRP bypass.

Reboot your Galaxy S24 Ultra to the 'Hello' screen. Tap on Emergency Call. Dial the secret code *#0*#. A white diagnostic menu must appear. If it doesn't, your firmware might be a specific carrier variant (AT&T/Verizon) which requires the MTP-to-Browser exploit, discussed in our MTK Auth Bypass Tutorial.

STEP 02

Executing the SamFw Exploit

Choose the 2026 security method for the best results.

Launch SamFw Tool V5.x on your PC. Connect the S24 Ultra. Navigate to the Samsung tab and look for Remove FRP (New Method 2026). The tool will begin sending "Exploit Strings" to the device via the diagnostic port. This process usually takes 45 to 90 seconds.

STEP 03

The ADB Handshake (Critical)

Don't forget to check the "Always allow" box.

Watch the phone screen. A popup titled "Allow USB Debugging?" will manifest. It is vital that you check the box "Always allow from this computer" before clicking OK. This grants the SamFw tool the authority to clear the FRP partition bits in the system root.

Deep Dive: Troubleshooting "Sahara" and "Port" Errors

Technicians frequently encounter the "Sahara Fail" or "Connection Timeout" error on the S24 Ultra. To fix this, perform a 'Hard Reset' via Recovery Mode, clear the cache partition, and try again on a USB 2.0 port. For more on this, check our S25 Ultra FRP Guide.

Your Galaxy S24 Ultra is now fully accessible.

The 2026 Definitive S24 Ultra FAQ

1. Is this bypass permanent after a Factory Reset? Yes. Unlike "Bypass Apps" that only hide the lock, the SamFw ADB method clears the persistent data block permanently. 2. Does it work on the Galaxy S24 Ultra Android 16 Beta? Surprisingly, yes. The diagnostic menu exploit is a hardware-level feature that Android 16 still supports. 3. My device is stuck on "Waiting for ADB" - What now? This is a driver conflict. Uninstall the "Samsung Mobile USB" device in Device Manager and let Windows Update find it again.
