I changed a shift point the other night and then hit the flash cal button just like normal and it erased memory, started to write and then froze about 4 seconds in. After I waited for several minutes to be sure it had indeed froze, I went ahead and hit the stop button. Now the truck will not start and when I try to read or flash and gives the message:

pcm did not accept the bootloader, reason: efilive could not unlock pcm. Then it wants me to enter the unlock code.

What does this mean? Did I cook the pcm? Any way to fix it? I have never locked the pcm.

Best regards,

Ben
