I have 1 doubt.. I could try this myself, but I'm scared it will make my phone to be unusable... My question is that, if suppose I have a passcode on my phone. And as a fact, I know that you cannot restore from iTunes by clicking the restore button directly, nor can you erase all contents from your phone without typing/removing your passcode... But what if u restore via dfu/recovery mode? I mean, iTunes recognizes the device and says its in recovery mode, you don't need to turn off find my iPhone.. I don't know if the passcode thing also applies to this ... Can anyone help me out? If my phone is lost, can they restore and use it via dfu?
