Please help (urgent) - Car won?t start

Process of disassembling the PCM, shorting a solder joint while turning on Ign and programming a full write all at the same time. It has worked on about 15 I have done and 3 were permanently bricked and unfix-able. One I unbricked 4 separate times.

Question, to unbrick the PCM like you are explaining here I should have advance skills right? I have the same issue that is been discussed here in my 04 Hummer H2 with P59.

I pulled all possible fuses and tried to write the Calibration did't work them entire calibration didn't work ether. I have brand new battery from 2 hours ago. And the message saying Brickable appear in the "Vehicle Writer" window.

You think I need to buy a new PCM?

Thanks in advance

All of those models will show the "Brickable" message when you use the Write Entire option. That doesn't mean that it will get bricked. There are a few videos on how to unbrick it in case it does happen.
