Two key points need to be noted⚠️ ① As long as the system remains at version 26 or above, it can be directly installed for diagnosis; If downgraded to the old system in the later stage, this cable will experience sleep failure.⚠️ ② Before installation, do not fasten the screen cable in advance. Prioritize installing the sleep cable before starting the system for diagnosis, which has the highest calibration success rate.APN:821-05921-A A3448Packing Includes: 1 Pcs LCD Sensor Cable
