| Error Message | Cause | Solution | | :--- | :--- | :--- | | “Sahara Fail: QSaharaServer fail” | Wrong driver or USB cable. | Use a short, high-quality USB 2.0 cable. Disable USB 3.0 in BIOS. | | “Firehose error: No response from device” | Device is in “Deep Flash” or secured by Xiaomi’s Auth. | You need an authorized Mi Account or an EDL cable. | | “NOP error: Cannot open device” | Another tool (MiFlash, QFIL) is using the COM port. | Close all other flashing tools. Restart v3.0. | | “Partition table not found” | Rawprogram0.xml is corrupted. | Re-extract firmware. Ensure the XML matches the device’s partition layout. | | “Hash mismatch” | Anti-rollback protection (ARB) triggered. | You cannot downgrade firmware. Flash a version equal or higher to current ARB index. |
