1. Short the Pins (If the drive is completely dead)
If your drive isn't detected at all, you must open the plastic casing. Locate the two test pins (often labeled TP or the two large pads near the crystal oscillator). Short them with tweezers while plugging the drive into the PC, then release.

3. Start the Process
4. Interpreting the Result
v1043 (1.0.4.3) is a relatively mature version, supporting:
Earlier versions (v100x, v101x) had buggy NAND support. Later versions (v106x, v108x) added newer chips but sometimes removed support for older NAND types.
FirstChip (often labeled as iStor or Innostor in older circles) is a dominant player in the value SSD and USB controller market. If you bought a cheap 64GB or 128GB drive from a no-name brand on an e-commerce site, there’s a 70% chance it has a FirstChip controller inside.
While they aren’t performance leaders, they are recoverable. That is their superpower. firstchip mptools v1043 fc1178 fc1179
Version 1043 is considered the "Goldilocks" build for these two controllers. Newer versions (v106x, v108x) tend to lock out certain "black chip" NANDs, while older versions don't support the 1179 correctly.
Key features of v1043:
| Error Code | Meaning | FC1178/FC1179 Fix |
| :--- | :--- | :--- |
| 0x01 | Flash ID mismatch | Manually select NAND type from the dropdown. |
| 0x03 | Bad block overflow | Increase Bad Block Ratio to 12 or 14. |
| 0x07 | Write precheck fail | The NAND is physically dying. Try lower capacity (e.g., force 50% size). |
| 0x10 | Driver not loaded | Reinstall the filter driver from the Driver folder. |
| 0x21 | Firmware download fail | Re-download v1043 (corrupted firmware file). Switch USB port. |
Version v1043 has dedicated tabs for these controllers. Key options:
The controller line includes the FC1178 (often USB 2.0) and FC1179 (often USB 3.0). Over the years, Firstchip released dozens of MPtool versions (v1005, v1020, v1030, v1040, v1043, v1053, etc.).
Version 1043 occupies a "goldilocks zone" for several reasons:
MPtools is destructive. It does not recover data; it resets the drive to a factory state. If you have family photos on that drive, send it to a professional data recovery lab before running v1043. Go to "Other Setting" :
For the DIY repair enthusiast, however, Firstchip MPtools v1043 is the ultimate lifesaver. It turns e-waste back into a functional (though potentially slow) USB drive. Keep a copy in your repair toolkit, disable driver signing, and always run the "Erase All" routine twice.

FirstChip MpTools V1.0.4.3 is a specialized Mass Production Tool (MPTool)
designed for repairing and managing USB flash drives powered by controllers, specifically the Key Features and Compatibility Controller Support
: This version is tailored for various FirstChip controller models, including Device Recovery
: It is primarily used to fix common USB errors like "No Media," "Write Protected," or "0 Bytes" by reflashing the drive's firmware. Bad Block Management
: The tool can scan the NAND memory for bad sectors and mark them as unusable to restore functionality, though this often results in a slightly reduced storage capacity. Language Support disable driver signing
: While often distributed in Chinese, the interface can typically be switched to in the right-hand settings column. Usage Guide for USB Repair Using these tools will erase all data
on the flash drive. Before proceeding, verify your drive's controller using a diagnostic tool like ChipGenius to ensure it matches the FC1178 or FC1179 part numbers. Preparation : Download and extract the FirstChip MpTools FCMpTools.exe
. If prompted with a "Product Type" window, keep the default settings and click Interface Setup
: Change the interface language to English in the right-side menu for easier navigation.
: The tool should automatically detect your connected USB drive. If it doesn't appear, try refreshing or checking your connection. Start Repair
to begin the scanning and flashing process. This can take anywhere from 30 minutes to over an hour depending on the drive's size and health. Completion
: Once finished, the drive should show a status indicating success (often a green indicator), and the partition will be accessible again. for a different controller brand?
