Disconnect all other external storage devices to prevent accidental flashing.

Once your device is recognized by your computer, follow these instructions to configure and execute the repair using the software:

When a flash drive suffers from corrupted partition tables, firmware glitches, or controller lockouts, standard Windows formatting tools fail. MPTool bypasses the operating system layer, talks directly to the Phison PS2307 controller, and reinitializes the hardware. Step 1: Confirm Your Controller with ChipGenius

If the drive is completely unresponsive to Windows, you must bridge the hardware test points (using a pin to short the data pins on the controller chip or NAND) while plugging it in to force the controller into . This forces the device to communicate with the MPTool software. Phase 2: Choosing the Correct Software Suite phison ps2251-07-ps2307- mptool

If your drive is bricked to the point where Windows doesn't even make a connection sound, you must manually trigger Test Mode . Carefully open the plastic casing of the USB drive. Locate the Phison controller chip. Use a needle or a small flathead screwdriver to short-circuit the data pins (typically pins 29 and 30) on the flash memory chip while plugging it into the USB port. This forces the controller into a safe bootloader mode, allowing MPTool to recognize it again. Conclusion

Once completed, close the MP Tool, safely remove the USB drive, and then reinsert it. The drive should now be detected by your operating system as a fresh, usable device.

When a flash drive's controller enters a panic loop or its firmware sector degrades, it loses communication with the NAND flash memory chip. This results in distinct hardware symptoms:

It must explicitly state PS2251-07 or PS2307 for this specific MPTool to work. Understanding MPTool Functions

If your drive has stable hardware components, use the Phison MPALL Production Suite to restore its original functionality. Step 1: Preparation and Extraction

The Phison PS2251-07 is a common USB 3.0 controller found in many budget and mid-range flash drives (Kingston, Corsair, SanDisk in some models, and generic “high-speed” sticks). It supports multiple memory chips (2 or 4 channels) and is generally reliable—until it isn’t.
