BL Locks Engineering Support cable — a service cable for technicians that supports BLlocked phones and CPUlevel operations for models 4S, 4C, 4i, and 5. Key benefits Resolve BL lock and account lock issues without hardware swaps: advanced 9008 mode bypasses BL lock to allow deep flashing and unlocks that otherwise stop ordinary tools. Recover phones from software failures quickly: enter 9008 mode via the engineering line to system software and revive devices without replacing font libraries. Preserve and recover user data: enter REC mode to unlock and extract data safely during or recovery operations. What it does BL lock & CPU support: fully supports phones with BL lock and CPUlevel access for models 4S, 4C, 4i, and 5. Advanced 9008 mode: bypasses BL lock to clear swipe/unlock/account lock problems and perform deepbrush flashing. System software : use the engineering line to place the phone in 9008 mode and restore a bricked or softfailed system without unnecessary component changes. Data unlocking and recovery: enter REC mode with the cable to access and recover user data. Practical attributes Function: engineeringline cable for entering 9008 and REC modes, bypass operations, deep flashing, and data recovery. Compatibility: explicitly supports BLlocked phones and CPU processors for models 4S, 4C, 4i, and 5. Construction and durability: built for repeated bench use with reliable connectors and robust cable shielding to maintain stable connections during operations. Form factor: compact, servicefriendly length and lightweight design for ease of use on the bench and in field . Performance: stable, fast mode switching and reliable communication with target devices to reduce time and increase firstpass success. Typical use scenarios recovery: Technician receives a 4i phone softbricked after a failed update. Use the engineering line to enter 9008 mode and deepflash the correct firmware to restore the system without replacing parts. Account lock or FRP bypass: A device is locked to an account or cannot pass swipe/unlock. Use the advanced 9008 bypass to remove the lock and restore functionality quickly. Data rescue before hardware work: Client needs data recovered from a 4S device before performing a hardware . Enter REC mode with this cable to extract and back up important files safely. Why choose this cable Specifically designed for BL lock and CPUlevel operations on listed models. Enables advanced workflows (9008 and REC modes) that avoid unnecessary component changes and preserve user data. Durable, serviceready construction and dependable performance for professional environments.
