Hi.
1) Suggest to flux and clean up the left side of the bios @ UH8. From the posted angle, there is an appearance of a few shorts. Each contact must be a clean soldered connection to the main logic board.
See here as an example:

Note that each of the 4 solder points are clean.
2) See attached.

Hi, i cleaned the board and checked the traces add some solder mask, missing parts are on the board now - according to locations and values from pictures, skipped RT1136 and RH133 since both of them are 0 ohm and on MB the traces are bridged.
There is one more issue now, it turn out the UH8 (bios) didn't survive and its not responding any more, i already found the bios file, unfortunately i don't have 25q256 around so i need to order it.
I'll keep you updated, thank you for your support.
