It is not that simple,, it takes time taking info out and getting new info back in.
A blip is a nice word, the car could just wake up and a blip during this process could be enough to corrupt the ECU,, it can be impossible to reinstate it again to re program. You need mains powered back up when doing these jobs, a spike from a poor change over from the power station can kill it all.
We had the thread last night with the failed comand show error "failed up date"
And no most updates go through OK, but again as Peter said things can go wrong, the micro might just fail, there are no answers to it all.
OK that makes a bit more sense, i was taking the blip as a network drop rather than what you have said, i was going down a completly different direction.
Thanks
