What is YGDP Tool?

YGDP Tool is the official flashing and maintenance utility developed by Yulong Computer Telecommunication (Coolpad). It is created to flash factory firmware packaged in the proprietary .CPB (Coolpad Packet Binary) format.

CPB firmware packages contain all operating system images (bootloader, recovery, system, radio, and user data) bundled into a single file. YGDP unpacks and writes these partitions over USB to restore or unbrick the device.

Install compatible Coolpad and chipset USB drivers before connecting.
