Chapter 3
- Preferably three or more:
The first one will be used for exploratory surgery and getting familiar with the system general architecture, identifying tricky or dangerous sections/subsystems, soldering/soldering, probing, and so on without being slowed down by excessive concerns about burning a system you will need for actual testing. This doesn't mean you should be reckless with this one, nor that you will necessarily actually destroy it.
The second one will be used in case you destroy components in the first one, either for component cannibalization to fix the first one or because the first become too damaged. This will also be used to compare two systems later to see if some security elements aren't shared when they shouldn't be (ciphering keys, certificated, and so on) or to see if you can change a system's identity if it's relevant.
The third one will, since you are fairly familiar with the system at this point, allow you to gather pre-initialization...
