1. Primary Function of Engineering Cable: Can bypass the Bootloader (BL) lock, enabling deep-level flashing of the phone directly! 2. Compatibility: Supports Xiaomi phones with BL lock and Qualcomm chips. Does not support phones without BL lock or with non-Qualcomm chips! 3. Intended Use: This product is designed only for flashing operations, not for charging. Please use it appropriately! 4. Purpose & Limitation: This is a flashing cable used to repair system software faults. If the phone can enter 9008 mode using this cable, it can be repaired via flashing. If it cannot enter 9008 mode, replacing the eMMC chip (storage) is recommended! 5. Unlocking While Preserving Data: Unlocking the phone requires entering REC (Recovery) mode and using an assistant tool. If the phone cannot enter REC mode, the engineering cable cannot unlock it either! 6. Compatible Models: Suitable for Xiaomi 4S, 4C, 4i, Mi Note, Redmi Note 3, Mi 5 (Note: Not compatible with the upgraded version of Mi 5), Redmi 3; (Important Note): For some newer Xiaomi models (e.g., Mi 5 / 5S / Redmi 4A / Redmi 4 / 3S) running versions above 8.2, the engineering cable cannot force entry into 9008 mode. These require disassembly and short-circuiting specific points on the motherboard first, followed by using the engineering cable for flashing.
