Kill switch confusion??

I have heard countless theory on how the kill switch works.
I have stated many times it's a serial/hardware Id kill or at least those have a lot to do with it.I've heard it's in the latest firmware but how would that work if you registered recall/downgraded to stock/then updated again.If it still gets killed at that point it's a serial based kill because how could nvidia keep track of these recalled tablets.Duhh serial/id,etc..not software the software comes equipped with the kill ..I think if we changed the serials or what not we could disappear of the radar for good or if we could at least bypass these recalled Id checks somehow.Any suggestions??ideas??
How about Nandroid backup of new tablet and installed on old ??idk:silly:

Shield Kill Switch

Hi figured we could use our own separate thread to discuss the killswitch Nvidia supposedly put in place on our old Shield tablets and see what has worked for those who have received their replacement units. If you've gotten a replacement please share if your old unit has been destroyed or not...if not please let others know what the old tablet has on it or what you did to attempt to prevent the brick! Thanks for helping us all out here!
