: Always execute the primary executable ( FTWUSB.exe or AlcorMP.exe ) as an Administrator . Step 3: Flash the Firmware Usb-firmware-tool-alcor-au6366-au6371
The hardest part is obtaining the exact firmware revision. Sources:
If you have confirmed your device is a card reader with the AU6366/AU6371 chip, and you are ready to proceed with the repair, follow these steps carefully:
Use the utility or QCTOOL to temporarily change the device parameters back to the standard factory values ( VID: 058F , PID: 6387 ). This will allow the main MPTool to register the hardware interface. 4. Adjusting the Setup Options Note the hardware ID (from Details tab → Hardware Ids)
These are USB 2.0 multi-format flash memory controllers designed primarily for and flash drive combo devices .
Always back up any original firmware before flashing, and never cross-flash between chip revisions. Treat the tool with respect—it’s a scalpel, not a hammer.
The tool will present you with several options. Here is what they typically mean: Flash ID Code: ECD798CA - Samsung - 1CE/Single
When a USB drive stops working, standard Windows tools like Disk Management or CHKDSK often fail. In many cases, the problem is not physical damage to the memory chips, but rather a logical issue in the device's control logic—specifically, a corruption of the firmware that manages the memory or a failure in the controller's internal management data. This is where specialized recovery tools come into play, and one such solution is the .
Before using the USB Firmware Tool, make sure you have the following:
