But after investigating this issue thoroughly, it turns out that there are multiple causes that might end up causing this particular error code. Here’s a shortlist of potential culprits that might be responsible for the error code SU-30638-0:
Method 1: Checking for a Server Issue
Before you try out any of the other fixes below, you should take the time to investigate whether there are any ongoing PSN problems that you should be aware of. As a lot of users have confirmed, you can expect to see the SU-30638-0 error code in instances where there’s a widespread server issue that is affecting the update delivery function. In this case, the only thing you can do is try to pinpoint the issue by checking on the PSN Status Page. Once you’re inside the PSN Status Page, check every service and their associated subcategory to see if Sony is currently reporting problems with their critical infrastructure services. Note: If the investigation you’ve just completed did reveal a server issue, the problem is entirely beyond your control. The only thing you can do is wait for Sony to fix their server problems. On the other hand, if you’ve just confirmed that there are no server issues to speak about, move down to the next potential fixes below to attempt to fix the SU-30638-0 error code locally.
Method 2: Performing a Power Cycle
If you didn’t do this already, your next step should be to eliminate an issue that’s caused by some type of corrupted temporary file/s. If this scenario is applicable, you should be able to fix the vast majority of relevant issues with a simple power cycle procedure. This operation will essentially restart your console while making sure that temp data from the previous sessions is no longer being used.

Method 3: Installing the Update using Safe Mode
If you’ve made sure that this is not a server issue and the power cycle procedure didn’t do you much good, chances are the pending firmware update that’s causing the error is not getting recognized by your PS4 system. In this case, you should be able to get around the issue by forcing the firmware installation from Safe Mode. This method was confirmed to be effective by several affected users that were also dealing with the SU-30638-0 error code.

This operation is also done from the Safe Mode menu, but there are some key requirements that you need to take care of between getting there.
