The FirstChip MP Tool is an ongoing project. Older versions (2017, 2018) often lacked support for newer 3D NAND nodes or had buggy algorithms for TLC flash. The "new" iteration of the ChipYC2019 MP Tool introduces several critical improvements:
Note: When searching for this tool, look for files named FirstChip_Mptools_2019_[Date] or ChipYC2018_V20_04_07 (though "2019" is the chip family, the tool may be dated 2021-2024). The specific binary is often referred to simply as "APTool" or "MPTool."
Manufacturers load the tool with a configuration template and flash hundreds of drives in sequence.
The ChipYC2019 is a mass production (MP) tool designed for USB flash drive controllers manufactured by FirstChip Technology (formerly ChipsBank). The "new" version typically refers to post-2019 firmware updates that support newer NAND flash types (e.g., TLC, QLC, 3D NAND) and improve compatibility with Windows 10/11. This tool is essential for low-level formatting, firmware flashing, bad block management, and capacity restoration.
Key conclusion: The tool is powerful but risky. It is primarily for factory use or advanced repair. Incorrect settings can permanently brick the drive or cause data loss.
| Error Code | Meaning | Solution | | :--- | :--- | :--- | | Error: Bad Block too many | The NAND flash has exceeded the factory defect limit. | The drive is physically dying. Reduce capacity manually in settings (e.g., force 16GB on a 32GB drive). | | Error: Compare Fail | Firmware mismatch or bad USB connection. | Re-seat the drive. Try a different USB 2.0 port. Use a different version of the MP Tool. | | Error: Timeout | The NAND chip is not responding. | The chip may be dead or cold-soldered. Try reflowing (not recommended for novices) or discard the drive. | | Tool Crashes on Start | Driver conflict. | Reboot Windows with driver signature enforcement disabled (Advanced Startup). | | Capacity shows 8MB | The controller is in "panic mode" – the MP Tool didn't complete. | Redo the process. Ensure "Erase All" is checked before starting. | firstchip chipyc2019 mp tool new
Step 1: Extract and Prepare
Extract the MP Tool archive to a folder on your desktop (avoid long directory paths or system folders). Run MPTool.exe as Administrator.
Step 2: Configure Settings
The interface will be sparse. Click the Setting button (often a gear icon or a button that says "设定"). The password is typically blank or 123456 or 111111. If prompted, try 320 (a common FirstChip debug password).
In the setting dialog, you will see multiple tabs. Pay attention to: The FirstChip MP Tool is an ongoing project
Crucially: Find the dropdown or option for "Erase All" or "Full Erase." For a bricked drive, you want a full chip erase, not a quick format.
Step 3: Connect the Device
Plug in your malfunctioning ChipYC2019 USB drive. The tool should immediately detect it, displaying the controller name, flash ID, and current capacity (often incorrect, like 0MB or 8MB).
Troubleshooting: If the drive isn't detected, try a different USB port (USB 2.0 ports are often more reliable for recovery). Also, ensure the drive is not in a USB hub.
Step 4: Start the Process
Click the Start button (绿色三角形 / green arrow). The tool will begin:
A progress bar will show percentage. A green circle with "PASS" indicates success. A red circle indicates failure (usually a bad flash chip or physical damage).
Step 5: Post-Processing
Once "PASS" appears:
Run a Windows Error Checking (right-click drive > Properties > Tools > Error Checking) and a speed test (using CrystalDiskMark or H2testw) to verify the health of the NAND. Note: When searching for this tool, look for
