Generally what happens is that progress will stall whilst you are trying to update the firmware or software/games on your PS3, causing it to be corrupted. Your console is then unable to function properly, and you are left trying to "pick up the pieces" as it were. The PS3 error 80710723 is one of these system update errors, and is often experienced by gamers who use wireless connections to update their firmware or games.

So how can you fix PS3 system update error? Here are a few steps you can take to try and fix the 80710723 error code yourself.

1. In your System Options/Network Settings you need to go and disable a setting called "media server". Doing this has been reported to fix the PS3 system update error in a number of different cases.
2. If you are using a wireless network connection then switch to a wired connection and attempt to update your console. Wireless connections can have interference, or fail from time to time. Therefore it is better to use a wired Internet connection where possible.
3. As a last ditch resort you can actually download the update from the Sony website onto your PC, then load that update onto a USB stick and plug it into your PS3 and carry out the update process from there. However, it is best to actually try and fix your connection problems first.
