Issues Encountered | Issue | Severity | Mitigation | | :--- | :--- | :--- | | Windows Driver Conflict | High | Used zadig to force libusb-win32 for the device. | | Firmware mismatch (2251-03 vs 07) | Critical | Manually specified 2251-07 in INI; auto-detect failed. | | "Read Only" after flash | Medium | Re-ran MPall with Preformat + Erase All + Maintenence Mode ticked. | | USB 3.0 timeout | Low | Switched to USB 2.0 hub during firmware download phase. | 7. Conclusion & Recommendations Conclusion: Phison MPall v3.72.0b is a functional but risky production tool for PS2251 controllers. It excels at recovering bricked drives but lacks modern safeguards (e.g., no flash chip voltage check). Version 3.72.0b is stable for PS2251-07 but fails unpredictably with PS2251-03 (needs v3.63c).
