Do not touch, bump, or unplug the USB drive during this process. Interrupting a low-level flash can permanently brick the controller chip.
3 to 15 minutes depending on drive capacity.
Click on the button (usually located in the top-right corner). If prompted for a password, leave it blank or try 123456 . Adjust the following parameters based on your goals:
| Error Code | Meaning | Solution | | :--- | :--- | :--- | | | Device not responding | Reinstall driver; restart PC; use USB 2.0 port | | Error 0x28 | NAND ID mismatch | Your chip is not in the CHIPYC2019 DB. Try a different MPTOOLS version (2020 or 2021). | | Error 0x43 | Bad block table full | The NAND is dead. No recovery possible. | | Stuck at 50% (Sorting) | Unstable NAND voltage | Remove power, short the NAND pins 29-30, replug. |
Return to the main MPTOOLS interface and click the "Start" button. The process will begin, and a progress bar will appear in the bottom-left corner. The operation can take a considerable amount of time, sometimes over an hour, especially when performing a factory reset on high-capacity or problematic chips. Let it run uninterrupted.
Allows setting a specific capacity for the drive.
MPTools utilities are notoriously unstable when running through modern USB 3.0 or USB 3.1 ports. For maximum reliability, plug your drive into an older, black-colored USB 2.0 port on your motherboard.
This comprehensive guide covers everything you need to know about FirstChip MPTools, from identifying your drive's controller to executing a successful firmware re-flash. What is FirstChip MPTools (ChipYC2019)?
Unlike standard Windows formatting which only touches the file system, MPTool operates at a far lower level. It directly communicates with the controller on the drive, allowing you to perform , which involves completely erasing the flash memory, rebuilding the controller's firmware, repartitioning the drive, and reinitializing the translation layer that maps logical addresses to physical NAND memory. In the context of U.S. manufacturing and quality control, the tool is often referred to as a FirstChip USBDM product tool for mass production testing and validation.
: Before using this software, users typically use tools like ChipGenius or Flash Drive Information Extractor to confirm the "Controller Vendor" is FirstChip and the "Controller Part-Number" matches the supported list.
When you first open the software, it may initialize in Chinese or ask you to choose between "End Product" and "Test Rack". Select either option, as it does not negatively impact the repair process.
Try a USB 2.0 port instead of a 3.0 port. Low-level tools are often more stable on older ports.
Because this is a proprietary tool intended for manufacturing and repair, it is not hosted on FirstChip's public website. However, many technical communities and repository sites have preserved copies. The most reliable sources include:
