How can I totally reset my iPhone? (Like a factory new)

Was this iPhone jailbroken at any time?

Because that error is often associated with restoring a jailbroken device and as jail breaking is not supported by Apple (it actually voids all warranty support from them) it is not not considered appropriate to discuss it here.

Try a Google search and you may find solutions on other forums though.

Don't listen to people claiming your phone doesn't deserve support simply due to their ASSUMPTION that your phone is jailbroken. You never stated whether it was or not. So all options available to restore your phone should be mentioned.

Put the phone into DFU mode and reinstall the OS.

Entering DFU Mode on iPhone, iPad or iPod touch

1. Plug your device into your computer with a USB cable.
2. Turn off the device.
3. Hold the Power button for 3 seconds.
4. Hold the Home and Power buttons for 10 seconds.
5. Release the Power button but keep holding the Home button.
6. After about 15 seconds you will be alerted by iTunes saying that it has detected a device in Recovery Mode.

Make sure the device screen is blank and no logos are present

From there you can re-install the latest iOS 9.0.2 release totally fresh. This is the last resort method if you are having no luck by simply pressing "Restore" in iTunes.

Well that didn't work, got any more?

Are you sure you put it into DFU mode? Was the screen blank or did it show a picture of an iTunes logo? Have you tried using a different USB cable? Yours might be frayed, bent, or faulty to where it works fine for charging but not for data transfer.

Dulyfuly - downloading and messing about with illegally hosted ipsw files from some anonymous web site in Montenegro is not likely to help you much in getting back to a proper and legitimate installation of iOS.

Seriously, spend 2 minutes on Google looking up that error, and IF it is a result of being jalilbroken, you will find suggested solutions easily (although no guarantee they will work).

Otherwise, you'll need to take it in to an Apple Store and see what they say, as that error is not one specifically listed under any Apple trouble shooting steps or guides.

They are not illegally hosted. Do your research. The links are pulling directly from Apple servers and if you knew anything about MD5 checksum and HASH you would know this. It's simply a directory to quickly access the files. They are not hosted there.

It downloads from this URL which is Apples server - http://appldnld.apple.com/ios9.0.2/031-37244-20150930-8AA55C68-64A1-11E5-9BD8-C3 E351D92A8C/iPhone4,1_9.0.2_13A452_Restor…

IF you want you can download it from iTunes and don't extract it. Then go to C:/Users/YourName/AppData/Roaming/Apple/iTunes/iPhone Update Software and get the same file.

Hi Mike

Ignore nemesis, he's just out for some way to waste his and everyone else's time. His posts are already being deleted, let him make a bigger hole to stand in.

The only one wasting time is the person offering ZERO solutions and reporting posts that point out that fact. That's why they were deleted. Offer some assistance instead of badgering those helping out just because you disagree with JB.

Who did the OP thank? Me or you?

He thanked the person who posted a solution that did not work, was that you?

Oh, of course it was

You do understand how a support community works, no? You offer solutions that the OP has not yet tried to try and HELP them. You've done nothing except post a comment that it didn't work when he already said it didn't work. Is stating the obvious your job? I think I should pass the shovel to you. No surprise that a quick Google search of your username results in various postings dedicated to you and none of them positive.
