Specification: Item Type: Service Cable Material: PVC Compatible Models: Qualcomm-based MIUI smartphones Main Function of the Engineering Cable: - Enables firmware flashing on devices with bootloader lock enabled. - Used for repairing devices with system software issues. Successful entry into 9008 mode via the engineering port allows repair. If unsuccessful, firmware replacement is recommended. Data Protection and Unlocking Guidance: To access recovery mode, use the appropriate button combination on the device and follow instructions provided by official MIUI tools. The engineering cable requires the device to successfully enter recovery mode to function as intended. Instructions for Use: Method 1: With the phone powered off, connect the engineering cable while simultaneously pressing and holding the cable’s switch and the phone’s power button for approximately 5 seconds. Once the computer detects the device and displays the 9008 port in Device Manager, firmware flashing mode is active. Use official MIUI flashing tools to complete the process. Method 2: Power off the phone and enter Fastboot mode by pressing Volume Down and Power buttons. After the screen goes black, press and hold the designated button (as per device model) for 5 seconds, then release. If the 9008 port appears in Device Manager, the device has successfully entered firmware flashing mode. Proceed with flashing using compatible MIUI tools, selecting appropriate settings before initiating the update. The screen will remain black throughout—this is normal. Package List: 1 x Flash Cable 1 x Type-C Adapter Note: Supports Qualcomm-based MIUI phones with bootloader lock enabled. Not compatible with devices without bootloader lock or non-Qualcomm chipsets.
