❓ FAQ & Troubleshooting

Device Not Connected / Not Recognized

In most cases, the drivers included with FolkTool are sufficient to recognize most devices on the market. If your device shows "Not Connected" or cannot be recognized in the tool, please try the following steps:

  1. Check Data Cable: Ensure you are using the original or a high-quality data cable, and connect to the rear USB port of the computer (for desktops).
  2. Manually Install Drivers: If the tool's built-in drivers cannot recognize the device, you may need to manually install generic ADB and Fastboot drivers.

Flashing Failed

  • Please ensure that the boot.img you selected matches the current system version (stock image).
  • Ensure that the Bootloader is unlocked.
