No. According to @levipope the damage is physical:
However, it is not clear if the damage is limited to just the diode or other components on the board are damaged too.
My best guess is that Rev 10 has cheaper/underspecced diode and that eventually all those motors will fail as the motor brushes degrade and generate higher voltage transients, short of aggressive firmware update that limits both the max voltage and max current by something like 20-25%.
They will need to replace them with another board revision, that has electronic components specced to survive larger voltage spikes.
As much as I sympathize with OP argument, I just don’t believe vex would open up schematics or let mentors replace diodes with higher specced ones before they fail. If I had any rev10 motors I would RMA them all right now before vex runs out of replacement options.
