The user encounters the issue when he tries to install a game through the disc but encounters the following message: Cannot start the application. (CE-30005-8) Some users encountered the same error code while connecting an external drive to the PS4. In some cases, the error code was also shown when creating a backup of the PS4 console. You can fix the error code CE 30005 8 on PS4 by trying the solutions below but before that, check if your PS4 has enough space available (e.g., if the game needs 20GB space, then make sure your PS4 has 40GB space available). Moreover, check if replacing the cable that connects the PS4 and hard drive solves the issue. If the issue is with an external device, then check if formatting the drive in the exFat file system on the PC and creating a single MBR partition of the whole drive solves the issue. If the issue is linked to a game’s disc (you can check the disc on other consoles), check if cleaning the disc thoroughly solves the issue. Following methods of cleaning the disc (multiple tries) are reported by the users to solve the issue:
1. Restart the PS4 Console, Clean Disk, and re-plug its Power Cable
A temporary glitch of the PS4 Console may cause it to show the error code CE 30005 8 and restarting the PS4 station may solve the problem.
2. Reinstall the Problematic Game
A partial install of the game may force the PS4 to “think” that the game is installed and thus cause the error CE-30005-8 even though all the files will not available for operation. In this context, removing the partial install and reinstalling the game may solve the problem.
3. Update the System Software of PS4 to the Latest Built
An outdated system software of PS4 may cause the PS4 error code CE-30005-8 and you can fix the “cannot start the application CE 30005 8” error by updating the system software of PS4. If the issue persists, check if using a different network solves the PS4 issue.
4. Rebuild the Database of the PS4 Console
Your PS4 may show the error code CE-30005-8 if its database is corrupt. In this context, rebuilding the database of your PS4 console may solve the problem. Before proceeding, make sure you have backed up the essential data of the PS4 console and remove any disc present in the disc drive of PS4. If that did not work, enable the debug mode of the console and open Debug Settings. Then navigate to Game > Add Content Manager > Entitlement Control > Game and delete Disabled Entitlement. Then check if the PS4 error code CE 30005 8 is cleared.
5. Reset the PS4 Console
The corrupt firmware of your PS4 may cause the error CE 30005 8 and initializing it which will reset the PS4 console to the defaults may solve the PS4 problem. Before proceeding, make sure to back up the essential data to a USB device (or create an online backup).
6. Reinstall the System Software of the PS4 Console
If initializing the PS4 did not do the trick for you, then you are left with no other choice but to reinstall the System Software of the PS4 console. Before proceeding, make sure to back up the essential data (as all PS4 data will be erased) on the PS4 console. If none of the solutions did the trick for you, you may get a new game’s disc (if encountering the issue with a disc) or get your PS4 checked for a hardware issue.
