Feature:<br> 1. Designed for MIUI engineering service, this cable supports Qualcomm-based MIUI phones and enables access to 9008 mode for deep flashing.<br> 2. Compatible with models that have BL lock, including MIUI 4S/4C/4i, MIUI NOTE series, NOTE3 Full Network, MIUI 5, and 3.<br> 3. This service cable is intended for system software repair. If the device can enter 9008 mode via the engineering port, it can be restored. If not, firmware replacement may be required.<br> 4. Bypasses BL lock to enable direct deep flashing of the device.<br> 5. Constructed with high-quality PVC material for durability and long-term use.<br> Specification:<br> Item Type: Service Cable<br> Material: PVC<br> Compatible Models: MIUI smartphones<br> Main Function of the Engineering Cable:<br> - Enables bypass of BL lock for deep flashing operations.<br> - Used for flashing devices with system software issues. Successful entry into 9008 mode via the engineering port allows repair. If unsuccessful, firmware replacement is recommended.<br> Data Protection and Unlocking Guidance:<br> To unlock the device, enter RECOVERY (REC) mode using the appropriate button combination and use compatible software. The engineering cable cannot be used if the device fails to enter REC mode.<br> Instructions for Use:<br> 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, deep flash mode is active. Use official MIUI flashing tools to complete the process.<br> 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 deep flash mode. Proceed with flashing using compatible MIUI tools, selecting appropriate settings before initiating the update. The screen will remain black throughout—this is normal.<br> Package List:<br> 1 x Flash Cable<br> 1 x Type-C Adapter<br> Note:<br> Supports all BL-locked Qualcomm-based MIUI phones. Not compatible with devices without BL lock or non-Qualcomm chipsets.
