As noted on USBDev.ru, some firmware versions can cause low performance after a repair. Try a different version of the BN07/FW07 bin files.
Using an MP Tool is a high-risk, high-reward activity. Download and run a hardware diagnostic utility like
It allows you to rewrite the .BIN and .FW files directly to the chip.
Using MP Tool will completely erase all data on the drive. It is not recoverable afterward.
Insert your corrupted USB drive into a native (USB 3.0 ports cause packet dropouts during flashing). Execute the diagnostic tool. Look for these key attributes: Controller : Phison PS2251-07 (or PS2307) Flash ID Code : (e.g., Toshiba TC58NVG7T2JTA00 or Hynix TLC) MP Ver / Firmware Ver : Displays current stock parameters.
