Question damaged pins/pads on i7 7700, burned? short circuited?

[lofej]

Hello,

I was hoping to find answer but coulnd find a relatable topic so i made this.
So, I got this CPU Intel i5 7700, from a friend..who used it for a while then made an upgrade, MBO/CPU, so sent me this CPU, he says have no idea what happend so I cant say first handed what happend to it before hand, as far as I know this couldnt be overclocking issue, the pictures will speak for them selves, I tried the cpu at a friend and it wont boot.

My question is, can anyone guess what happend and can it be repaired?

on the video might be seen better, 5 pins damaged

Two photos (for some reason doesnt allow me to insert image directly, so here is the link)

I think excessive current through the pads could have caused the discoloration.

I think yes, but how was he able run and use the processor all that time? or this could've happend during dismounting? maybe with still connected PSU?
Also its not a discoloration, its that brass or gold plating layer is missing and that grey layer is showing under.

Perhaps the CPU won't boot now for some other reason.
I don't think that the plating missing 100% means it's won't work.

What motherboard are you using?
Does it have necessary BIOS update to support i7 7700?

I dont have a test MBO/PC, and I cant recall what MBO or bios version my friend had at the time we tried, but I remember we checked the support list for this cause and everything was green.
