Seeking to upgrade PS5 to 4.03/4.51 Firmware

[icarus86]

Please help! I bought a NIB PS5 a while back and have only ever fired it up to test it. It’s currently on FW 2.50 but I would like to upgrade to 4.03 or 4.51 (so I can at least get down on some Horizon!) but I’m not certain the safest way to do so.

I’m certainly going to manual USB method but I’m having a really rough time finding the PS5 OFW download links. Of course Sony only ever offers the latest. Are older versions hosted on here? Or should I maybe just try to update it via the Horizon disc?

Any help is greatly appreciated!

Here are some PS5 OFW mirrors, if you're unable to remain on 2.50 lower is preferred so 4.03 would be advised over 4.51.. or get a second / used PS5 to play retail games and keep your current PS5 on 2.50 for future tinkering
