Run the executable (usually named FirstChip_MPTool.exe or similar).
If the drive is fake, you can sometimes use "Mass Production Tools" (MPTools) specific to FirstChip controllers to "un-patch" it and restore it to its true, much smaller capacity. Recommendation
Since VID/PID can be generic, the most reliable way to find the correct repair tool is to identify the actual chip: usb device id vid ffff pid 1201 patched
Users encountering this issue typically report the following symptoms:
This is a default or invalid Vendor ID. It means the USB controller chip has lost its programmed vendor identity and is running in a low-level, generic mode. Run the executable (usually named FirstChip_MPTool
A "patched driver" scenario involves using methods to circumvent DSE to run an unsigned repair tool. This is not a custom driver for the FFFF:1201 device, but rather a workaround to give a technician access to the right tool.
Insert your VID FFFF PID 1201 USB drive into a native (avoid USB 3.0 hubs, as they can disrupt the low-level flashing handshake). It means the USB controller chip has lost
VID_FFFF&PID_1201 is the USB equivalent of a "system error" message—it tells you something is broken, but not specifically what. The "patched driver" you may hear about is actually a workaround to use specialized, often unsigned, recovery tools. With this understanding, you are now equipped to better diagnose the issue and weigh the risks and rewards of attempting such a recovery. If the device contains critical data and the procedures described seem too complex, it is best to consult a professional data recovery service.
