Re: 6.0 swap into 1990 RCSB
Outside of the poor quality stepper motors and tungsten filament bulbs...
Cracking solder joints on the banks of SMT resistors and dodgy voltage regulators are the most common failure points I've found on the T800 clusters. And the ham handed amateur repair attempts.
There are a few other issues that occasionally rear their ugly heads but they are not common.
Bricking during a flash has usually happened because of voltage sagging. It corrupts the flash and the PCM freaks out. Sometimes you can lie to TIS and tell the software you're flashing a new device.
I have yet to get into a PCM ECM, that didn't present actual physical board damage, that I couldn't coerce back to life.
All bets are off on scorched boards from burned components. I've resurrected one but usually they are just dead dead dead. 8-)
