Outdated NBA 2K17 version. This is the most frequent reason for which players will see EFEAB30C or 4B538E50 errors. The good news is that this can be easily fixed by updating the game. If one of these two error messages is displayed, it means that players need to stop from doing the current activity and let the game download and install the latest version. If the game doesn’t start downloading the update and players are sure that there is an update available, they can try playing some online modes. This will normally cause the game to go into the update mode. When the game has finished downloading the updates, players will be asked to go to the main menu. The game will install the updates and everything should go back normal.

Reserved space has been deleted. This also has something to do with updates. Reserved space is a section claimed by the game for future updates. Most of the times, this section will not contain anything so players will be tempted to delete it to free some space. The trouble is that NBA 2K17 cannot function without this section. The reserved space issue can be solved by uninstalling and reinstalling the game. This can be time-consuming and very annoying so the best thing to do is just ignore the reserved space section.

Account confirmation update. In some cases, players will get the above errors if their account and registration email are not confirmed. This can happen even after an initial confirmation has been made. This is easily solved by signing into the game from the official website. Players need to enter their MyPlayer name and password. The confirmation is done automatically. As a precaution, players can login into the NBA 2K17 website from time to time to keep their account confirmed. This is not one of the most common causes of the errors but it can happen. We share this article to help you avoid troubles while buying NBA 2K17 MT and playing the game. We will keep posted it if you think this is useful.
