Before downloading a tool, you must confirm your exact controller and Flash ID.
Download ChipGenius or Flash Drive Information Extractor: These free tools identify the controller model (e.g., AU6989SN-GTC ) and the Flash ID.
Note the VID and PID: These are 4-digit hex codes (usually 058F and 6387 for Alcor) needed for the tool to recognize your device. Phase 2: Download the Correct Tool
The primary source for these tools is USBDev.ru, which hosts various versions of AlcorMP and AlcorU2MP. For AU6989SN-GTC

Driver Cleanup: AlcorMP installs a temporary filter driver (mpszfilt.sys). Always close the program properly to uninstall it, or you may face USB issues after a reboot. Troubleshooting Common Errors
Device not recognized: If your VID/PID is non-standard, use the Alcor Change PID/VID Rework tool to reset them to standard values before flashing.
"No Flash Found": Your drive might be in a "deep sleep" state. You may need to manually short the pins on the NAND chip (Test Mode) to force detection.
