T2 not reading factory pcm

[orange345]

Anybody else have issues with t2 not reading the factory pcm 2014 rt 5.7

Only really happens if the pcm had been previously tuned by something else.
13/14 have bootloaders that everyone handles differently and if you used something else to swap the bootloader in the past, that pcm is stuck with that tuner/brand or the pcm needs to be replaced unfortunately.
