Converting a Samsung Galaxy S9 SCV38 (a Japanese variant typically from AU or Docomo) to the international G960F firmware is a common request for users wanting to remove "bloatware," unlock all global network bands, and enable standard features like Bixby Voice that may be restricted in regional ROMs. Core Concept: Crossing the Hardware Gap
The SCV38 and G960F use different processors. The SCV38 is built on the Snapdragon 845 chipset, whereas the G960F uses the Exynos 9810. Because of this hardware difference, you cannot simply flash official G960F firmware onto an SCV38; doing so will likely result in a "brick" (rendering the phone unusable).
Instead, "conversion" usually refers to flashing a Global/International ROM designed specifically for the Snapdragon hardware, which mimics the G960F's software experience while maintaining hardware compatibility. Key Prerequisites for Conversion
Unlocked Bootloader: Japanese Samsung devices often have locked bootloaders. You must check if your specific SCV38 allows OEM Unlocking.
Odin Tool: The standard software used to flash firmware onto Samsung devices.
Correct Firmware/ROM: You need a "Global Port" or a US Snapdragon ROM (like G960U) that has been modified for the SCV38. Scv38 Convert To G960f
Data Backup: Flashing new firmware wipes all data from the device. The General Process
Identify Current Version: Check your current binary version (U1, U2, etc.) in the recovery menu to ensure you are downloading compatible firmware.
Enable Developer Options: Go to Settings > About Phone > Build Number (tap 7 times) to enable USB Debugging and OEM Unlocking.
Download Mode: Power off the device and boot into Download Mode (typically Bixby + Volume Down + Power).
Flashing with Odin: Load the modified "Global" firmware files (BL, CP, AP, and CSC) into the Odin tool on a PC. Converting a Samsung Galaxy S9 SCV38 (a Japanese
Final Setup: Once the process is complete, the phone will reboot. You may need to manually set up APNs for your specific carrier to restore LTE/4G data. Benefits of the Global ROM Conversion
Removal of Japanese Apps: Eliminates pre-installed AU or Docomo bloatware that cannot be deleted otherwise.
Network Optimization: Fixes issues with USSD codes and network mode switching (LTE/4G/3G).
Language Support: Adds full multi-language support and standard Samsung boot animations.
Functional Features: Restores standard Bixby functionality and helps bypass Factory Reset Protection (FRP) in some cases. Important Risks Port a G960F ROM to SCV38 (custom firmware
Hardware Mismatch: Never attempt to flash Exynos firmware (G960F) on a Snapdragon device (SCV38). Always use a ROM explicitly labeled for the SCV38 Snapdragon variant.
Warranty/Safety: Modifying firmware typically voids your warranty and may permanently disable features like Samsung Pay or Knox security.
It seems you’re asking for a guide or content related to converting or porting the SCV38 (a Japanese variant of the Samsung Galaxy S8, model number SM-SCV38, typically for au / KDDI) to G960F (Samsung Galaxy S9, international Exynos model).
Before proceeding: This is not a standard or safe conversion. The SCV38 is an Exynos 8895 device (Galaxy S8 family), while the G960F is an Exynos 9810 device (Galaxy S9 family). Direct conversion is impossible. However, you may be looking to:
