I tried to flash a stock 06 redline this weekend and had major problems
V2 firmware 2.06.35 may 3, 2010
boot block 2.06.03 mar 3 2010
Software ver 7.5.6 build 117
Pcm Os is 12605256
Cal is 12603031
I was able to read the calibration just fine then I made a few modifications and went to flash.
V2 reported that the pcm was not licensed to the cable so I went ahead and locked the pcm to the cable
Then I started the flash and that’s when things went south, it loaded the boot loader and then failed during the flash. Well it never really started the flash I don’t think.
Tried again and it says no pcm detected. Turn the key off and waited a few mins and tried to start the car and nothing.
Tried the flash again and still nothing. Tried a cal and os flash and still cold not talk to the pcm.
Pulled the battery for 5 mins and got the same error
Called a friend that works for a local gm dealer and he says disconnect both the positive and negative battery terminals and then connect for 20 sec to discharge the car.
Tried again and nothing
Now the bad part is the pcm is now locked to my cable
Any ideas?
