Click the button on the right-hand margin of the window. The software will scan your system's USB bus and display your drive inside one of the numbered grid channels.

If the MPALL tool cannot detect your USB drive, you may need to use a tool called (also found on USBDev.ru) to read the VID/PID and IC controller directly from the device's current state. Key Considerations

When a USB flash drive becomes corrupted, locked into a "Write Protected" state, shows a "No Media" error, or stops responding entirely, standard operating system formatting tools like Windows Disk Management or Rufus will fail. In these critical situations, low-level factory production software like Phison MPALL is the definitive solution to bring the hardware back to life. Decoding the File Name

Incompatible USB 3.0 port architecture, or software lack of driver clearance.

If successful, the status bar will turn green, and the drive will be "reborn" with factory settings. Important Safety Warning ⚠️

Repair drives that are unrecognizable or corrupted.

In the context of USB flash drives, "mass production" refers to the initial factory process of writing firmware, formatting, and configuring a drive for use. This tool allows end-users to perform similar low-level operations, effectively allowing you to "re-manufacture" your USB drive.

NAND flash memory can shift into a permanent hard-locked "Write Protected" state when the controller detects critical bad blocks or a data transmission timeout. The MPALL tool clears the internal flash registers, maps out damaged sectors, and rewrites the translation table to restore read/write access. 2. ISP (In-System Programming) Firmware Flashing

: It is primarily used to fix "bricked" or unreadable drives, such as those showing "Disk is Write Protected" or "Please Insert Disk" errors.
