What Is Relock Tool?

RelockTool is a small server-side program that connects your computer to an online unlocking system. A special login loader is included, which allows users to log in and use the internal network unlock feature.

The tool uses a local credit system, meaning the credits are stored on your computer, not directly on the server. If the server accepts these credits, the unlocking process completes successfully. If not, you may face errors during operation.

⚠️ Important: This tool is only for Samsung devices. Other brands are not supported.
