If all pins are fine without any damage or sticking, the CPU probably isn't dead. Give it a slight bend just enough to fit. You're likely still got some residue left from the cleaning process. It's best to spray it with IPA and let it dry completely, then gently clean the pins with a clean toothbrush.
Already tried on the CPU, now it should re-slot but nothing appears at startup. It might not be the CPU itself—there could be residual thermal paste in the socket. You could attempt to remove the CPU socket and clean it thoroughly.
Sure, there are additional checks needed to confirm a mobile device functions properly, but you can't gather details without a CPU. It's essentially an inert piece of metal and plastic.
Remember, kids, you should clean your CPU's 1331 pins daily! Would using a fanned brush with soft threads be better? A toothbrush might be too tough, and compressed air could work if you have it.
It's feasible to take off the socket cover. This person did it with an AM3 board, I don't have videos for AM4, but it seems likely they used a similar approach. Once you remove the cover, gently wipe the paste down; I recommend a stronger contact cleaner than IPA.
Paintbrush or compressed air seems like a solid plan. I’ll pick them up next week when I return. I should have mentioned I’m at my brother’s house now. I need to head home and be back by late next week. I handed him an old Athlon II x2 270 Regor processor for use in an AM3 system. That gives him something at least.
