– A green circle means your drive is back to factory state. Red means a fatal error—usually a bad flash chip or mismatched firmware.
Before downloading any software, you must confirm your chip version. Phison naming conventions can be confusing, but PS2251-07 and PS2307 generally refer to the same hardware architecture.
When you run the MPtool on a fake drive, it will show the true Flash ID and memory density (e.g., "Micron 64Gb – 8192 MB"). You can then set the MPtool to format only the true capacity (e.g., 8GB) to make the drive reliable again. Never trust the sticker on the drive; trust the Flash ID in the MPtool.

If the MPTool fails to detect your flash drive, or if the process yields a "Flash ID Error," you may need to use a physical hardware trick called (or Shorting the Pins ).
Before using this tool, you must verify your hardware. Using a tool like ChipGenius Flash Drive Information Extractor is critical to ensure your controller is actually a PS2251-07 (PS2307)
(often called MPALL in the Phison ecosystem) stands for Mass Production Tool. It is a specialized, proprietary software suite developed by Phison intended primarily for factories to program and test thousands of USB drives at once. For the everyday user, MPTool allows you to: Flash new firmware onto the controller. Perform a low-level format to erase damaged sectors. Remove stubborn write-protection. – A green circle means your drive is back to factory state

If you follow this guide—especially the bridge mode activation and the version selection—you can restore 80% of "dead" PS2251-07 drives to full working order. Just remember: respect the tool, verify your firmware, and always test the drive thoroughly after a successful flash.
: The drive allows you to read files but rejects any deletions, partition adjustments, or formatting attempts, displaying a permanent "Disk is Write-Protected" error. Phison naming conventions can be confusing, but PS2251-07
Flashing firmware requires meticulous preparation. Using incorrect parameters will permanently brick the controller. Gather these digital assets before proceeding: 1. Hardware Diagnostic Tools
: If you brick your drive, physical shorting of pins may be required for recovery—this requires technical expertise.
No physical shorting? Sometimes repeatedly plugging/unplugging while holding the reset button (if your drive has one) works, but most PS2251-07 sticks don’t.
Click the button on the right-hand side. Your device should populate one of the white status boxes with an associated drive letter or target index. Click Start to initiate the flashing routine.
