This is a very common "sub-id error" that indicates a communication issue between the tool and the NAND flash chip.
: Utilizes two distinct binary layers—a Burner Image ( BN07*.BIN ) to initialize the hardware, and a Firmware Image ( FW07*.BIN ) to manage the file allocation system. Step 1: Diagnose and Extract Chip Information
Before downloading tools, you must know your specific Flash ID. Use a tool like ChipGenius to find the and Flash ID code . Example ID : 98 3A 98 A3 (Toshiba TLC). 2. Choose the Correct Flashing Tool
Download a compatible mass-production bundle, such as or v3.13.00 , from a verified database like USBDev.ru Phison Repository . phison ps225107ps2307 upd

To fix this, you must flash new firmware (a process known as UPD or UPDTool) onto the controller. The most effective tool for this is the or Phison MPALL . 1. Identify Your Controller
You may need to use a specialized driver in the MPALL folder for the "PRAM" device.
Before downloading files, you need your flash drive's unique signature. Use a tool like ChipGenius to find the and Flash ID code
While MPALL is the standard tool, ST-TOOL is a newer, related tool that can also handle sorting and firmware updates.

Phison PS2251-07 (also widely known as the PS2307) is one of the most common USB 3.0 flash drive controllers on the market, found in devices from brands like Kingston, PNY, and Silicon Power. It's a reliable chip for everyday use, but like all storage hardware, it can sometimes encounter problems such as write-protection errors, capacity drops to 0 MB, or the drive failing to be recognized by Windows. In these scenarios, the only effective solution is often to perform a "reflash" or "update" of the controller's firmware, a process known in the community as an "UPD." This comprehensive guide will walk you through the process, from diagnosing the controller to successfully restoring your flash drive to working order.
This process will permanently erase all data on your flash drive. Phase 1: Identify Your Controller
Features a single 8051-compatible 8-bit microprocessor core and uses a "burner" firmware system where code is loaded from the NAND into RAM at boot. Key Features
Identify the data pin lines on the NAND flash chip. For standard TSOP-48 flash packages, the data lines are usually located on or pins 41 through 44 .
