Download from the developer file server—not a mirror.

Use the current setup and companion files published at the UnlockTool developer source. Confirm the address before downloading.

The address should be file.unlocktool.net. Avoid shortened links, re-upload sites and archives sent by unknown accounts.

Compare the file name and published version with the newest developer notice before installation.

Complete extraction before launch. Do not run the application directly from a compressed archive.

Install only the drivers needed for the brand, chipset and connection mode you plan to use.

Confirm the application opens and your licensed account signs in, then connect the authorized device in the required mode.

Troubleshooting

If the download or setup fails

The download does not start.

Check the developer source address, browser error and internet connection. Wait for a verified source rather than switching to an unknown mirror.

Files disappear after extraction.

Review the browser download result and Windows Security Protection History. Record the detection name and affected file before changing any setting.

The tool opens but does not detect the phone.

Treat this as a separate device-connection issue. Check drivers, cable, USB port, connection mode and exact device state.

Can I download before buying?

The setup source and account licence are separate. Software availability does not itself grant access to licensed operations.
