Why? The most common reason to need to find out your Apple devices ECID is so you can use TSS Saver, and save an authentication ticket so you can install an iOS/iPhone/iPad/etc Firmware version after apple stops signing, that is after they stop allowing the currently allowed firmware version(s) to be installed. All models except for the iPhone 6S Just need your device type and ECIM, the 6S also needs the CPU model which can be one of two things (I have the N71AP- I don't know off hand what the other possible CPU model is).
