How do you get profiles back on COD4 after deleting?

To recover deleted profiles in Call of Duty 4, you can try restoring them from a backup if you have one. If the game was played on a console, check if the console's cloud storage or external storage has a backup of the profile. Unfortunately, if there is no backup available, the deleted profile may be permanently lost, and you would need to create a new one. Always ensure to regularly back up your game data to avoid such issues in the future.
