Hello, I was informed by a friend that a DFU restore is essentially the ultimate wipe/restore for an iOS device. Can someone explain why this is and what exactly it does? I understand it restores the phone to factory defaults, but how does it differ from a Recovery Mode restore or just a regular iTunes restore? Also, I cannot seem to find the right steps to perform a DFU restore on Apple's website...and the steps I find online all differ slightly...can someone who's done this confirm what the steps are? Thanks for your help and explanation in advance.
