I just reflashed with the new 1250003c OS to my 2005 truck and it would not let me flash my bin into the blank OS. The mesage came up that said I needed to "license this pcm" It would not let me reflash as it came back up with the same license message. I had to relicense my pcm to be able to flash my file into it. It failed twice but on the third time it worked. It seems to have changed my engine # and reset my engine hours also. this is all I have found so far. I have flashed this pcm over 50 times and 3 complete OS flashes before and never had a problem. Did I do something wrong or do we have a problem somewhere else? On the other hand it seems to have fixed the A0008 problem.
