If the software cannot start the write process, you may need to enter "Test Mode" by manually shorting pins on the controller chip (advanced users only). Safety and Risks Using an MPTool is a "nuclear option" for USB repair.
Download a hardware identification tool like ChipGenius or Flash Drive Information Extractor. Plug in your USB drive. Look for the "Controller" or "Chip Model" line.
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. phison ps2251-07-ps2307- mptool
In the "Flash Setting" tab, keep it on "Auto Detect" unless you know your specific NAND chip ID. 3. Executing the Flash Open the main MPTool application (e.g., MPALL_F1_9000.exe ).
