Before the V1400 tool can interact with your device, your computer must be able to "see" it through a specific interface.

Drivers: You must install the Marvell AT Interface drivers. Without these, the tool will not detect the device on a COM port.

WTPTP Drivers: For deep flashing or recovery, specialized WTPTP drivers for x86 or x64 systems are often required.

USB Cable: A high-quality data cable is necessary to maintain a stable connection during the flashing or unlocking process. How to Use the Portable Tool

Extract the Files: Once you have the Marvell MiFi Tool V1400 portable folder, unzip it to your desktop.

Install Drivers: Manually add the Marvell AT interface driver via Windows Device Manager if the device is not automatically recognized.

Run the Tool: Open the executable. The tool should automatically or manually detect the COM port assigned to your MiFi.

Execute Commands: Depending on your goal (e.g., "SW Upgrade" or "Unlock"), you will load the necessary firmware files and click the start button. Warning: Selecting the wrong COM port or disconnecting the device during this process can permanently damage the hardware.
