T7Rollback

T7Rollback is a simple and clean tool designed to roll back Call of Duty: Black Ops III to the version before the February 19, 2026 update. This is especially useful for players who rely on mods like T7Patch or T7x that were broken by the recent game update. The goal is to provide a straightforward, safe, and hassle-free way to restore an older version without manually messing with SteamCMD or game files.

Features

• Rollback to a specific BO3 version – restore compatibility with popular mods.
• Automated SteamCMD integration – downloads the correct old depot and manages files.
• Safe overwrite of game files – ensures your installation is properly replaced.
• Automatic cleanup – temporary files in %AppData%\T7Rollback are removed once done.
• Checks running processes – prevents Steam or BO3 from running during rollback to avoid conflicts.

How to Use

1. Download the latest release from this repository.
2. Run T7Rollback.exe.
3. Follow the on-screen prompts:
   • Enter your Steam username when asked.
   • SteamCMD will handle login, depot download, and file replacement.
4. Wait for the tool to finish. Once done, you’ll see All done! :).

Note: You must log into SteamCMD using your Steam credentials.
