Important Guidelines & Technical Rules:
1. Prerequisite Setup Mandatory:
- Download and install the specific Infinity CM2 module setups (e.g., CM2MT2, CM2SP2) and all prerequisite USB drivers (MediaTek VCOM/Preloader, Spreadtrum SPD, Qualcomm 9008) on your PC BEFORE requesting the connection.
- Install the required client software (**USB Redirector Client**).
2. Dedicated Single-Session Policy:
- The shared dongle port is assigned exclusively to your connection for the entire 40-minute duration.
- Any attempt to split, proxy, or forward the virtual USB connection to third-party machines will result in an immediate session kill with NO REFUND.
3. 40-Minute Timer:
- The 40-minute timer starts the moment the virtual Infinity Smart Card is detected and mounted in your Windows Device Manager.
- Have the target handset prepared (correct boot keys, testpoint ready, or firmware file unzipped) to maximize your bench productivity during the active window.
4. Server Operations / Online Credits:
- This service provides unrestricted access to the physical dongle's smartcard authorization and offline tool operations. Online server credits or separate credit-based vendor authorizations (if applicable) are not included.
5. Non-Refundable Digital Service:
- Once the remote port has been shared and the smartcard is active on your workstation, the service cannot be canceled or refunded.
