I had the same idea, but no, I tried with a second, untampered one and I also got a working shell. So it does not seem to be dependent on the tamper state.

wtf? are you saying the shell can be hypothetically drilled for root access without triggering the tamper detection? that'll be ACTUALLY bad...

I think in the article it was even stated that the port is even accessible without drilling!
