Note: Because MPTool is highly specialized, it requires precise configuration files. Incorrectly configuring the tool can render your USB drive permanently unusable, so it is crucial to follow the steps precisely. Step-by-Step Guide to Using the MPTool

: Incorrect firmware selection or mass production parameters can render your drive permanently unusable ("变砖" or bricking).

A specific string of hex characters (e.g., AD DE 94 A7 42 48 ) that identifies the exact NAND memory vendor and generation (Hynix, Toshiba, SanDisk, Kioxia).

Locate the two data pins on the flash memory chip (usually pins 29 and 30).

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

For the PS2251-07, you need a specific version. The generic “MPALL” (MP Tool) or “ST Tool” (Simple Tool) must support your exact controller ID: VID 0x13FE (Phison) and PID 0x5500 (or similar, depending on the OEM).
