It might be a long story but your post was cut short....

I loaded a tune to the “new” ECM with EFILive, didn’t apply the RSA patch first. It gave a security “unknown” message after sending an unlock key, then after the message send an unlock key again and wrote the tune. That normal?
It takes writes and the truck runs fine other than some gremlins after the bricking of the original ECM from HP Tuners. When I turn the ignition to on, the exterior lights and instrument cluster illumination flashes twice. Other than that, everything is normal in operation of the truck.
If the ECM hasn't had the anti-tuning stuff turned off then it will still take a stock tune no problem.
Are you sure you started with the correct base calibration? (It will be written on the sticker on the 'dead' ECM).

Yessir, CM90032. Wasn’t a pure stock file that I loaded to the “new” ECM though either, truck won’t run right or very well without some particular modifications in the tune file.
