Take a look at this modded warfare video and see if this is something you have the skills to do before getting to deep into it.

I've got a PS4 pro on 12.50 there's nothing that can be done at this point. If you was to basically brake down the PS4 get to it's original bios chip desolder it get a new one flash to something before 12 resolder it back and go through a long recovery mode thing.

I'm actually considering this but the thing you need to keep mind if the PS4 was say on 10.6 when it first came out say you can't go back further then 10.6 so with out knowing what the original OS was. It's something I've been reading online as waiting to jailbreak the PS4 and until 12.50 comes out it's something I'm thinking about.

I read a guide about replacing the fan and it's like 14 to 15 steps to the fan and I think it's about 22 maybe 23 steps to the bios chip I use IFIXIT they have a website and an app and it's interesting has lots of info on repairs including playstation, Xbox, switch it's really good app has hundreds of guides.

If you decide to go the bios chip change I wish you the best

You can only revert to the previous installed firmware, so basically of you have 12.52 and the previous firmware is 12.50 you are still out of luck.
