Downloading the "best" tool is useless if it doesn't match your hardware. Before downloading any software, you must identify the controller inside your USB drive.

Warning: This process involves a "low-level format." All data on the USB drive will be permanently destroyed. Do not proceed if you are trying to recover family photos or important documents—use data recovery software first.

Procedure:

Even with the best free download, you might encounter errors. Here is the fix guide.

| Error Code | Meaning | Solution | | :--- | :--- | :--- | | “Not Support Flash” | Your specific NAND chip isn’t in the tool’s database. | Find a newer version of AlcorMP (e.g., v2.0.07 or higher). | | “Check Sum Error” | Corrupted download or mismatched firmware file. | Re-download the tool from a different source (try USBDev instead of Reddit). | | “Read Capacity Fail” | Physical connection issue or dead NAND. | Clean the USB contacts with isopropyl alcohol. If that fails, the chip is physically dead. | | Stuck at “Formatting 50%” | Bad memory blocks are being mapped out. | Wait 10 minutes. If still stuck, run the tool again with “Scan Bad Block” set to Level 3. |
