Cr*p, I knew it was a long shot, but I finally got around to checking my PS4 Slim 1TB and it's on 5.01.
I got it around this last Thanksgiving 2017 as the Star Wars Battlefront II Bundle here in the US from Amazon and let my Nephew play it during that week. I knew it had updated when he first set it up, but until now haven't wanted to see the damage. It was probably on a higher FW then 4.05 when I got it anyways, but now I know where it's at for sure. While plugged in just now to check, it started a 5.05 update download so I ripped the Wi-Fi router plug out of the wall to stop it. That's something at least. Probably not going to go out and hunt a <4.05 system down, so here's to waiting for a 5.01 solution...
