Using the SMI MP Tool has inherent risks:

(Actual speeds depend on NAND quality and USB port type.)

Verify that the tool automatically selected the correct firmware file path under the "ISP Version" or "Firmware" selection tree. If it is blank, manually browse the tool's subfolders to match your controller name.

Click (or press F5) to start the production process (firmware burning). Wait for the tool to show a green "OK" or "Pass" status. Remove the USB drive and re-insert it. Troubleshooting: SMI MPTool vs. Dyna MPTool

Set to 100mA or 500mA depending on your hardware type.

Extract the downloaded .rar or .zip file into a dedicated folder on your local drive.

Never guess which tool to download. Use (a free USB hardware identifier) to scan the drive. This tool will reveal the exact Controller Model (e.g., SM3257ENBA) and the Flash ID Code . Write these down. If ChipGenius cannot detect the drive, you may need to "short" two specific pins on the drive's circuit board to force it into hardware reset mode.

Download and run or Flash Drive Information Extractor (Antons Flash Drive Information Extractor) . Look closely at the report for the following fields: Controller Vendor: Silicon Motion (SMI) Controller Part-Number: e.g., SM3268AB, SM3257ENLT, SM3439
