How to Install Coolsand RDA USB Drivers for Infinity CM2 Working with keypad or feature phones powered by Coolsand/RDA chipsets often requires specialized tools like the Infinity Chinese Miracle-II (CM2)
dongle. To ensure your PC communicates perfectly with these devices for flashing, unlocking, or IMEI repair, having the correct drivers installed is the most critical step. Why You Need the Coolsand Driver
The Coolsand driver acts as the bridge between your Windows PC and the mobile phone's CPU. Without it, the CM2 software cannot "see" the phone when you connect it in boot mode.
Supported Tasks: Removing security codes, formatting, reading/writing flash files, and fixing power-on issues.
Compatibility: Most packages, such as the CM2RDA Drivers v1.01, support Windows XP through Windows 11 (32-bit and 64-bit). Step-by-Step Installation Guide News - 2017-08-23 - CM2RDA Drivers v1.01 package released

Installing unsigned or legacy drivers on modern Windows requires special steps due to Driver Signature Enforcement (DSE). Follow this guide meticulously.
The Coolsand Driver CM2 is a niche but critical piece of software for anyone working with legacy VIA/Coolsand-based feature phones and embedded devices. While installing it on modern Windows can be a challenge—requiring disabled driver signature enforcement and manual .inf selection—the process is straightforward once you understand the steps.
Remember to always download drivers from trusted community sources, avoid shady executable installers, and test the COM port connection before attempting any flash operation. With the driver correctly installed, you can breathe life back into old devices, recover bricked phones, and perform advanced repairs that are otherwise impossible.
If you continue to struggle, the Linux route or a dedicated hardware programmer will save you hours of frustration. But for 90% of users, the manual installation method described above will deliver a fully functional Coolsand CM2 driver.

Disclaimer: Modifying phone firmware, IMEI, or network locks may violate local laws. Always ensure you have proper authorization and ownership of the device before using these drivers for repair or modification.
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.
Once the driver is successfully installed, you can open the CM2RDA or CM2SCR module. Select the appropriate CPU type, and the software should now be able to communicate with the phone's internal storage and processor. This connection is the gateway to reviving "bricked" devices or recovering data from locked handsets.
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.

The Coolsand CM2 Driver (often part of the CM2RDA package) is a specialized bit of software designed for technicians who perform "surgery" on feature phones and older Chinese handsets. If you've ever had a "brick" of a phone with a Coolsand or RDA chipset that refused to talk to your PC, this driver is the digital translator that makes it happen. The "Life Saver" for Dead Phones
The Problem: Many basic phones (keypad style) use obscure Coolsand chipsets that Windows simply doesn't recognize out of the box. They often show up as "Unknown Device".
The Fix: This driver, specifically when used with the Infinity-Box CM2 Dongle, allows your computer to bypass standard locks, read flash files, and even remove security codes from devices that feel like they're from a different era. Top Features for Techies
Legacy Support: Works across almost every Windows version, from XP and Windows 7 up to Windows 10 and 11.
Boot Key Magic: It enables specialized boot modes—like holding down the ‘0’ key while plugging in the USB—to force the phone into a state where you can actually work on it.
Versatility: While it's built for the Infinity-Box ecosystem, it is a staple in the kits of Miracle Box users and forensic investigators who need to pull data from "dumbphones". The Verdict
It isn't a "consumer" product you'd buy for fun; it's a utility for the niche world of mobile repair. It can be a pain to install manually (you often have to point Device Manager to the specific .inf file), but once it's in, it is rock solid for flashing and FRP (Factory Reset Protection) unlocking.
