(Mass Production Tools) are the official low-level formatting and configuration utilities for FirstChip controllers. They are not intended for everyday users but for factories and repair technicians.
: If your drive was a "fake" (e.g., a 128GB drive that is actually 32GB), the tool will likely report the correct, smaller capacity after the repair. Source Verification
MPTOOLS is not meant for consumers. It is raw, unpolished, and often leaked onto the internet. When hardware enthusiasts get their hands on MPTOOLS, they can do things standard formatting tools can’t. They can repair "dead" drives, partition a single stick into multiple drives, or create a "Read-Only" lock. firstchip mptools chipyc2019
(short for Mass Production Tool ), also known as FirstChip MPtools or FirstChip MpTools , is a professional-grade utility developed by FirstChip Microelectronics Co., Ltd. (Shenzhen, China) – the manufacturer of the widely used FC1178 and FC1179 series USB controllers. It is the designated software for "mass producing" or "initializing" USB flash drives that use a FirstChip (also known as "一芯") controller.
The identifier chipYC2019 often appears when the original firmware on a USB drive has become corrupted, or when a cheap or counterfeit drive is attempting to mask its true capacity. In many reported cases, a drive initially shows as chipYC2019 after being misdetected following a failed Windows format or when the drive has severe logical damage. It is also the default "fallback" identifier that the controller uses when it cannot properly read the NAND flash parameters. Source Verification MPTOOLS is not meant for consumers
The physical NAND flash memory inside the drive is severely degraded. Open the settings panel, select a more rigorous Low Scan mode, and lower the target capacity to allow the tool to isolate the broken memory cells. Error: "Write Firmware Fail"
: Allows modification of VID (Vendor ID), PID (Product ID), and serial numbers. Key Usage Steps Using this tool will erase all data on the flash drive. They can repair "dead" drives, partition a single
Plug in your corrupted USB drive. The tool should automatically detect it in one of the slots (e.g., If it doesn't appear, click (or use "Port Refresh"). : For advanced users, you can click
