Alcor Micro USB Repair Tool: Fix AU6989SN-GTC and AU6998SN Controllers

If your USB drive has become "Write Protected," shows "No Media," or is unrecognized by Windows, it likely uses an Alcor Micro controller. Specifically, the AU6989SN-GTC and AU6998SN are common chips in many generic and branded (like Transcend) flash drives.

The specialized AlcorMP (Mass Production Tool) is the primary utility used to re-flash the firmware on these chips to restore functionality. Step 1: Identify Your Controller

Before downloading a tool, you must confirm your hardware matches. Use a diagnostic utility like ChipGenius to find your Controller Part-Number and Flash ID.

Target Controllers: AU6989SN-GTC, AU6998SN, or variations like AU6989SN-GT/GTA/GTB.

Default VID/PID: Typically 058F / 6387. If your VID/PID is different, the repair tool might not detect the drive until modified. Step 2: Download the Repair Tool

For AU6989SN-GTC and AU6998SN controllers, you need specific versions of AlcorMP that include support for these newer GTC/SN chips. Recommended Versions:

ALCOR U2 MP v20.09.16.00: Supports GTC, GTB, and SN series. Available on the ALCOR U2 MP Download Page. alcor micro usb repair tool au6989sngtc au6998sn link

AlcorMP v16.02.19: A stable version for many SN-GT models. Find it at FlashDrive-Repair.

AlcorMP MD Editions: These "Multi-Drive" versions are often better at detecting stubborn drives. Check the USBDev.ru AlcorMP MD Archive. Step 3: How to Repair Your USB Drive

Follow these steps carefully, as this process will erase all data on the drive.
