As I posted in this thread about Makerbot for Desktop 3.3 and firmware 1.4, when I tried to install firmware 1.4.0.188, this is what happened, repeatedly:





After about 4 tries an a wasted half hour, I gave up. Then, the next day I tried again, and instead of 1.4.0.188, it was simply 1.4.0, without the 188 at the end. And it worked. Nothing like deploying software without testing it.
