Battery?

820-3213 available, similar to 820-3214 but component placement is a little different.

MacBook Pro 13" 2010 absolutely requires PC3-8500 sticks, it won't work with faster ones.

GMUX firmware mod can still do brightness adjustment with either PCH microvia jumper (software and keyboard control, soldering is risky to perform), raw keyboard signal (no software control, some jumpers required) or custom driver (software and keyboard control, no soldering required), depending...

That's an 820-2915 not an 820-3115.

FIrst thing is to check CPU VCore resistance to ground. CPU likely shorted if the previous owner messed with CPU VCore circuit.

PP3V42_G3H doesn't make its way to the DC-in board, usually caused by bad FFC or J9500 indeed…

Why would you randomly reflow large BGAs for no reason? Good way to make sure to kill the board… LVDS line issue, often caused by GMUX. Can also be a broken trace elsewhere or a bad LCD connector.

see-ic still has some good ones (must buy them new with white underfill) but they are getting more and more expensive.

820-2249 will have dead GPU.

M1 needs to be working anyway since it contains encryption keys. You can still try to replace U8100, if you're very lucky M1 may be fine. But first you can try to remove L8100/L8101/L8102 one by one to try to isolate the phases if there is only one shorted.
