1 · Before you install anything
- Download only from the official domain listed — never from mirror sites or Telegram channels.
- Verify the file signature or SHA-256 checksum when the vendor publishes one.
- Uninstall conflicting OEM suites (Samsung Kies, HiSuite, Mi PC Suite) before installing a new USB stack.
- After installing, reconnect the device on a direct motherboard USB port (avoid unpowered hubs).

3 · macOS technicians
Most Android service modes (ADB, Fastboot, Samsung Download Mode) work on macOS without a vendor INF. For MediaTek BROM or Qualcomm EDL you may still need platform-tools and, in some cases, a Windows VM with the OEM driver — LandBech Tool surfaces the correct guidance inside the desktop app when you select brand and model.
