how to get iphone into dfu mode?
I have an iphone 4 and I need to get this phone into dfu mode so that I can change the firmware on the device. DFU mode is a situation where you can put your iPhone into where it can interface with iTunes but does not load the iPhone operating system or boot loader, this is where DFU mode differs from recovery mode. But I do not have any idea how to get iphone into dfu mode. If someone have any idea or know about it ……it would be great help
