Hacking Hardware PS4 Pro NVB-004 Firmware Revert help

[LoseSilent]

I'd like to do a permanent install like the MODDED WARFARE PS4 revert video but I cant seem to find information for my mobo revision. Anything that I do find seems to be contradictory.

PS4 pro Mobo version is NVB-004, Syscon is A05-COL2(?).

1. Can I read/write to my Syscon? I read that SIE INC is not supported so I'm not able to revert.
2. Where are the alternative solder points for my NOR?

Hopefully these pictures are helpful. I bought this PS4 used and still need to clean it but I wanted to see if the revert mod is supported first.

A friend of mine used this tutorial:
To revert my PS4 PRO.
It ended up a bit different due to using different hardware. But this is what got him started.

Yeah, the video they don't have a SIE INC Syscon so I'm pretty sure I'm not going to be able to roll back.

Edit: this says SIE INC isn't supported... but I don't see it anywhere else so maybe It's not a big deal?

Edit2: I think it's a non-issue for what I want. I see SIE INC in his video. As for different points, I guess I can just test myself or solder directly. If anyone has any other information please let me know. I'm going to order the parts now.

What fw are you on?
As of right now JB is public for up to 12.52, fw 13.00 is done and confirmed. Not public as of now.
We are waiting for Sony to allow disclosure on that one.

So before you order stuff to do a revert, have the above in mind. Might save you from doing the job.

The JB for up to 13.00 requires a bluray burner and Blu-ray Disc so invest in that instead if you don’t have it.

It's on 12.00. I already have a burner and a few disk so that's no problem.

I'm doing this for experience and as a fun project for myself. I have soldering experience and I'm confident I can do this but I am still learning.

Ok, I understand. Tinkering is always fun.

Just for info, you are probably just going to downgrade to a firmware that requires the same exploit that you need to use now.
So there is no benefit for you to downgrade.

But for knowledge and tinkering, go for it.

I had a hard time finding this information online so I wanted to share a bit. Below is a pic of my PS4 Pro NVB-004 board.

Red is the nor. I used a multimeter and the resistors near it (within the red) are what I soldered to. If, like me, you end up burning one, it's 0402 47Ω to replace it. the 4 vias between the NOR and Syscon are ground, I soldered to one of them instead of pin 8.

Blue is the syscon. You can lift leg 15.... if you break it off like I did.... use a grinder to grind the chip down a little at a time until you find something you can solder to.

Pin 16 is connected to the 2 resistors below it, or just solder to the leg. The same is true for legs 5 and 6, there are resistors you can solder to.
