Hi guys, sorry for been inactive but I had no time to keep working on the PS4. But now I have some news, unfortunately not very good.
So I kept searching and measuring and I found the following.

So all the components highlighted on the image are biping on my multimeter. I have included the ohms info I am getting so either are components with very low resistance or are shorted but I have no idea how to proceed seems very unlikly that all that components are really shorted but also I can't find a one component connected to all of them.
On top of this I tried to made a UART reading but also I am having some complications here... I made all the steps to patch the NOR and all went great. Now with the NOR installed back in the console and the cables connected to the right points on the motherboard and on the CH341A I am getting no reading. I tried Putty and UART reader software but I am not getting any readings ans still the console is doing the same 55 sec BLOD.

I turned the UART on before continuing with the process and of course patch the NOR.

Any clue?
