A Word Of Caution
When you DFU revive your iPhone, your pc erases and reloads every piece of code which controls the applications and hardware onto your own iPhone. There is the possibility of something to go wrong.
In case your iPhone is damaged at all, and particularly if it is water-damaged, a DFU restore may violate your iPhone. I have worked with clients who tried to reestablish their iPhones to resolve a slight problem, however, water had ruined another element that prevented the revive from finishing. A usable iPhone with minor problems can become completely unusable in case a DFU restore fails due to water-damage.
What is Firmware? What Does This Do?
Firmware is the programming which controls the hardware of your apparatus. Software changes all of the time (you set up programs and download fresh email), hardware not changes (ideally, you do not open your iPhone and rearrange its parts ), and firmware virtually never affects — unless it has to.
What Other Digital Devices Have Firmware?
All of these! Consider it: The washing machine, drier, TV remote, and microwave use firmware to control timers, buttons, and other standard functions. You can not alter what the Popcorn setting does on your microwave, therefore it is not software — it is firmware.
Apple workers restore a great deal of iPhones. Given the choice, I would consistently select a DFU restore over a routine or retrieval mode reestablish. This is not official Apple coverage and a number of techs would say it is overkill, but when an iPhone comes with a problem that may be solved with a revive, a DFU revive stands the best chance of fixing it.
