The Coolsand Driver for CM2 (Infinity Chinese Miracle 2) is a vital software component for mobile technicians working on feature phones powered by Coolsand/RDA chipsets. This driver allows your computer to recognize the handset through a USB connection, enabling the CM2 dongle to perform critical service tasks like flashing firmware, repairing IMEI, and bypassing screen locks.
Installing these drivers correctly is often the most challenging part of the repair process. Because many Coolsand devices are older or generic models, Windows may not automatically identify them. Without the specific USB-to-Serial bridge provided by these drivers, the CM2 software will return "Device not found" or "Connection error" messages.
The driver package typically supports both 32-bit and 64-bit versions of Windows, including Windows 7, 8, 10, and 11. For newer versions of Windows, you must disable "Driver Signature Enforcement" before installation. This is a security feature that prevents the installation of drivers not digitally signed by Microsoft, which often includes specialized mobile service tools.
To install the Coolsand Driver for CM2, first download the official driver package from the Infinity-Box support area or a trusted GSM forum. Extract the files and run the setup executable. If the package contains raw .inf files, you will need to use the Windows Device Manager to manually update the driver while the phone is connected in "Boot Mode"—usually achieved by holding a specific key (like the center button or '*' key) while inserting the USB cable.

Maintaining a clean driver environment is also essential. If you have previously installed conflicting RDA or MTK drivers, it may be necessary to uninstall them using a tool like USBDeview before setting up the Coolsand drivers. This ensures that the CM2 dongle has a dedicated, stable path to the device hardware for safe and efficient servicing.
