To bypass this restriction on a Snapdragon device, you must rely on specific firmware vulnerabilities and third-party paid exploits, such as the well-known "Sampak" or "Combo Firmware" methods developed by the Android modding community. Critical Prerequisites and Risks

The script will push root binaries via ADB and command the phone's boot sequence to bypass integrity checks. Step 5: Accessing Safestrap / Custom Recovery

The required flashing utilities are optimized exclusively for Windows.

For those who are truly adventurous and have a deep understanding of low-level Android development, there is the possibility of exploring hardware-based exploits. This involves using EDL (Emergency Download Mode) and Firehose programmers to attempt a forced unlock.

Click and wait for the process to finish. The phone will reboot into a bare-bones engineering user interface. Step 4: Execute the Exploit Script

The exploits available for the Snapdragon S9 only work on specific, older bootloader bit/binary levels (usually Bit 1 through Bit 3 or 4, depending on the specific exploit). If your Galaxy S9 was updated to the absolute final security patches released by Samsung, your bootloader binary version might be too high to exploit.

Another notable project is SamPWND, created by XDA Recognized Developer elliwigy. This service provides a set of modified Samsung firmware that allows root access without officially unlocking the bootloader. Initially developed for the Galaxy S8 and Note 8, it has been extended to support North American Snapdragon Galaxy S9 and S9+ units (SM-G960U/U1/W and SM-G965U/U1/W).

A specific engineering ROM matching your device model and bootloader bit level.

With your files ready, you must boot the phone into its flashing interface. Turn off your Galaxy S9 completely.

This process triggers a factory reset. Back up all data.

Example: If your build ends in G960USQS**7**CSK5 , your binary level is .
