I should also mention that I had previously removed P259 chip. Comms or bootload is not dependent on that, right?

* Comms or bootload is not dependent on that, right?

** Correct. After p259 removal, everything else should work if there was no problem (but then p259 wouldn't have been damaged). Otherwise (if the problem that damaged p259 remained) basically the board is sentenced to death.

** but if something killed the p259 chip (it really does not die just by itself: most likely insufficient ground connection) => if the harness was carefully fixed or if a solenoid or relay >300mA driven by p259 (or without flyback diode, although v3.8 has onboard diodes for the 6 p259 channels available on EC36 pins) damaged p259 => then it might have been fixed by the disconnection => there is some chance for the mainboard to survive.

** If the primary (harness or other) problem was not fixed, then removing p259 made it virtually impossible for v3 to survive. Apparently this is the case

*** p259 provided some protection (while sacrificing itself), but obviously it cannot provide any protection after it was removed.
