So I think I'll start from removing that water residue. I tried with clear water but it doesn't seem to help. Does anyone know any way of removing such residue without damaging board even more than it already is? My plan is:
- remove residue
- carefully dry it
- try if it works
- realize it doesn't
- solder out all valuable parts like capacitors and make them explode for lulz
- throw it out with satisfaction that I did everything I could
