I need to know exacly wich IC is the Bios and the eeprom to reset the password that i forgot or to replace the bios and...

There is no water resistant phone, one brand try that, those phone resisted normal water, but not salt water, so they paid a lot in waranty, you just had bad luck, but maybe is only the screen that is bad, by the way, is better to put the phone in isopropil alcohol for a day and then let it dry for another day or two.(i did that with my sister phone, after that i took the motherboard and scrub the parts where i found corrosion) In any case, you can know if the phone turn on by conecting it to a pc, if it conects after you try to turn it on then you have to replace the screen.

maybe your system didn't install the boot manager, try installing grub. search "grub for windows" in google
