If the drive isn't detected at all, you may need to manually short two pins on the flash chip (Test Mode) to force the controller into a state where the tool can see it. Phison PS2251-07 USB recovery Tools - Flash Drive Repair : There is no standard debugging interface like

: Often used for drives with "downgrade" or lower-quality NAND flash that require more intensive error-correction during the formatting process. MPALL (Mass Production Alliance) Phison PS2251-07 USB recovery Tools - Flash Drive

When you run the MPtool on a fake drive, it will show the true Flash ID and memory density (e.g., "Micron 64Gb – 8192 MB"). You can then set the MPtool to format only the true capacity (e.g., 8GB) to make the drive reliable again. Never trust the sticker on the drive; trust the Flash ID in the MPtool.

Repairing a Phison drive requires precision. Follow these steps carefully: 1. Software Preparation

This usually means the firmware file version is incompatible with your specific NAND flash. Try a different firmware (.bin) file.
