Reviving Dead USBs: A Guide to FirstChip chipYC2019 MPTools Ever plugged in a USB drive only to find it showing 0GB capacity, "Write Protected," or not appearing at all? If your drive uses the FirstChip FC1178 or FC1179 controller (commonly labeled as chipYC2019), you aren't out of luck.
The team was stunned. They had never seen anything like this before. Dr. Kim, however, was intrigued. She decided to explore this unexpected feature and created a custom tool, dubbed MPTTools Portable.
Identify Your Chip: Use a tool like ChipGenius to confirm your controller part number is chipYC2019.
: Fixes issues where a drive shows "0MB" or "No Media" by re-initializing the controller. Partition Management
While powerful, using MPTools is a "nuclear option." The process destroys all data
- Error Code = 0x104 (Bad Block Too Many): The NAND flash is physically dying. You can try to reduce the capacity by 50% in the settings to remap bad blocks.
- Error Code = 0x110 (ISP Download Fail): The controller is locked. You need to short two specific pins on the USB drive’s circuit board (pins 29 & 30 on the CBM2199) while plugging it in to force "ROM Mode."
- "Device Not Found" in MPTools: Your PC is using the standard USB drive driver. Use the portable tool's
InstallDriver.exeor manually update the driver in Device Manager to "F/W Download Device." - Wrong Capacity Detected (e.g., 16MB instead of 64GB): This indicates the firmware is corrupted. Run the "Erase All" option twice consecutively.
: Allows users to create multiple partitions, including "CD-ROM" partitions for bootable ISOs or hidden security partitions. Firmware Reflashing
Introduction
In the world of data recovery and hardware maintenance, few things are as frustrating as a "bricked" USB flash drive. For technicians and enthusiasts, the name FirstChip is synonymous with a specific category of controller chips used in millions of affordable flash storage devices.
