    Would someone explain the difference between a normal option-click Restore and a DFU restore?

    DFU is for when something is really broke and a regular Restore fails. Also, DFU is much more likely used in the jailbreak scene.

    DFU is if you don't want to take chances of something that might be still lingering...

    I always do DFU restore as NEW no backups no matter what, it's simple to do and makes me feel better even though I might not need to it. In all my years of owning iPhones I have never had any battery issues nor other similar problems, especially important if you like to jailbreak and play with tweaks.

    From iClarified: DFU means Device Firmware Update. If a restore using Recovery Mode doesn't work you will want to use DFU Mode as a last resort. When placing your iPhone into DFU Mode it does not load the OS before attempting the restore

    If DFU is low level and cleaner, why would anyone NOT chose to do so?

    Because it's not as easy to do and most times is not needed. The same reason why people don't secure trash whatever they want to erase from their computer.

    And why people forget to make backups before upgrading to a new unreleased firmware and run into trouble.

    If you are moving from beta to GM/final back up to icloud, do a DFU restore to GM, set up as new phone, and then back up from icloud.. Itunes backups also tend to backup bugs.. Icloud just backs up what you need and reinstalls all apps.. Much cleaner.. Still not 100%

    I'm curious now, is there a DFU mode for iPads as well?

    Of course.

    Same process for every device pretty much. I'd recommend just Googling how to do it, or watch a video - very easy.

    ----------

    I suppose it's not "Apple certified" because IIRC, but I might be wrong, it's actually a little more trouble booting it back out of DFU - jailbreakers of course have programs like TinyUmbrella to do it.

    As far as Apple are concerned once it's in DFU, you gotta restore it!

    It's not more trouble booting it back out, you are mixing causes of jb procedures that people do while in DFU mode, with the actual DFU mode.
