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.
