hello, I've tried several bios and they do not work well, it takes a while to start, I have their original bios works perfectly the only thing that does not have a serial number, I pass the original bios if someone can modify it.

Ref: 820-3536-a i5, 4gb 2015

Cannot be shared. 820-3536 has 8x RAM and 820-3476 has 16x RAM. I have one RAM IC ripped off with pads and tracks and your files cannot be used.

This doesn't matter, the main one is the voltage ...

even with the correct schematic you cannot fix the ram marked in the picture

Huh...? I have successfully repaired a bunch of damaged RAM and VRAM on Apple mainboards. The only problem here is that I cannot determine where to connect some points because there is no documentation available for 820-3476, and your documentation is not correct for my needs. That's why I asked form correct one.
