If you are experiencing an error message that reads “Su-42118-6”, there are a few things that you can do in order to fix the issue. First, make sure that your PlayStation 4 is up and running. If it is not, you can check to see if there are any updates available for it. If there are, then you can install them and try again. If not, then you may need to take some other steps in order to fix the error. If you have trouble finding the error message, then you may need to look at your system’s logs in order to find out what was causing the problem. This could include looking at your system’s software files and registry keys as well as your system’s performance data. Once you have located all of these sources of information, then you can start trying different solutions until you find one that works for you. Finally, if all of these steps do not work for you or if the error still persists after trying them all, then it may be worth considering purchasing a new PlayStation 4. This is because a new PlayStation 4 could potentially fix any errors that were caused by the original one.
