| Error Message | Probable Cause | Solution | | :--- | :--- | :--- | | | Corrupted USB cable or unstable power | Use a high-quality USB-A to USB-A cable. Connect device to a powered USB hub or directly to motherboard USB 2.0 ports (not USB 3.0). | | "Device Not Support" | Incompatible firmware or chipset | Double-check firmware name. Ensure you are flashing firmware built exactly for your device’s board ID, not just the SoC. | | "Check Chip Fail" | Driver issue or device in wrong mode | Uninstall Rockchip drivers, reboot, reinstall DriverAssitant. Try switching from Loader to Mask ROM mode. | | "Test Unit Fail" | Low-level NAND communication error | The NAND chip may be failing. Try a lower speed in config. Re-seat any internal ribbon cables. | | Tool freezes at 7% or 12% | Bad block in NAND or mismatched parameter | Erase IDB (Identify Device Block) first. In the tool, click "EraseFlash", then try Upgrade again. |
