So whats dfu mode? Basically its state of your device in which we got root acess(kind of).It is used in jailbreakes to put the cydia app and other sideloads.
Very difficult to enter and vice versa
It corrupts device and bla bla bla bla
How to enter it?😒
Hold your home and lock buttonuntil your screen goes black
Immediately release home when black screen appears keep pressing the lock.Wait for few sec until itunes recognize it in recovery mode(actually thats dfu) done😊
Keep pressing the home+lock for 8 sec and release home. Keep holding lock till lock screen appears.
