Annotations

  1. 1.0 1.1 Nano 6G and Nano 7G code execution is implemented using CVE-2010-1797
  2. 2.0 2.1 Nano 5G support is implemented in a tethered fashion via wInd3x, where we re-use parts of the original Apple boot chain which negates the need of some features.
  3. UART is not really needed here as we can already access the device via USB.
