Now that I *have* a bricked car, do you have any advice on what I should do? I'm thinking either the dealer, an "alternative" shop (All German Auto in San Diego), or pulling the DME and sending it to a tuner like ESS.
What would you do if the power went out in your shop during a flash and bricked the car?
I'd take the car to AGA. They know their stuff.
It is possible to resurrect a module which often involves making up a standalone harness and running the program out of the car, but worst case you replace it and move on.

Anybody know the price to replace the ECU? Cost of the part? Just curious the out-of-pocket costs should it brick.
Everyone I've talked to seems to think it's the lack of power supply that caused the problem. Even though it's in the PDF instructions, it's probably worth updating the first post in this thread to warn people not to attempt this without a quality power supply hooked up to the car.
The consensus from the experts is that I corrupted the operating system on the tcu, preventing it from accepting a new flash. I'm going to have them attempt to write to the chip while it's out of the car. If that doesn't work, I'm looking at a new TCU + Flash
if you can let me in (eg by teamviewer) i'll try to help both guys to get smg ecu work again.
pm for details

It's not related to power supply at least not for smg. Of course full car programming should always (and couldn't be even done without) done with stable power supply connected to car's batt, but up to 6-7mins flashing time could be safely done only on batt source.

I can't PM yet, or even reply to them.
If you can outline what you're thinking the problem is, that would be awesome.
I'm going to try the flash one more time tomorrow. If it doesn't work, I'm pulling the ECU and bringing it to either All German Auto or ESS. I've decided against the dealer, for sure.
