(adsbygoogle = window.adsbygoogle || []).push({}); Is there a way to update the psn store on PSITA 4.50 DEX? I don't want to upgrade firmware because the newer ones are made with cobra and ccapi isn't supported and target manager doesn't work. I Just want to have the latest psn store because the one I have now isn't updated with latest things.

The PSN store will prompt you to update when you start it up provided you have internet access (obviously).
Other than that, you might be able to find a .pkg to install an update for it but I've never heard of that.
