It's possibly true, and could have been cause by trying to jump start on a completely dead battery unfortunately, but without being able to see what all it's doing there's no way to say with certainty.
Sometimes they just get cranky and letting it sit with power disconnected and ignition switch in LOCK position it'll wake itself back up when a good battery is connected, but sometimes not.
If everything has had the faults cleared and it'll talk to the Tech2 and let you cycle the key and it still has no communication with CIM then it could be fried.
Just make sure none of the fuses got unintentionally popped during the jump-start attempt, go through the fault tracing procedure to make sure that CIM is actually getting power and it's not something else masking the issue.
