We’ll try to fix error 9 through both these options.
USB Port

Software & Hardware


One of the first things you can try is to change the USB port where the cable connects. This is too basic, I know, but you’d be surprised at how randomly this fixes all hiccups when trying to upgrade/update the firmware.

Another Computer

If you can access another computer / laptop with iTunes installed, the second thing you can try is to update/upgrade your iDevice on another computer. Yes, this is another basic thing to try.

Cable Disconnect / Faulty Cable

When the cable is unplugged/loose, the iPhone looses connection with iTunes. This leads to a plethora of errors (different numbers) and it looks like Error 9 (while not documented on Apple’s support page) could also be one of them.

Security / Anti-virus / Firewall

This is where it gets all about software.

If you’ve set up firewall or connecting through proxy/vpn, you should make sure that this is not preventing iTunes from connecting to Apple servers remotely. When you try to upgrade your iPhone/iPad, iTunes connects to Apple, checks for hashes, security keys etc. (a bunch of stuff that it uses to verify that your iPhone or iPad is technically “updatable/upgradable.”)

If sometime during the attempt, iTunes is stopped from connecting to Apple’s servers, it throws an error. Error 9 is a rarity even then (more common is Error #2 and Error #16xx). But still, since it’s documented, you must try to fix your firewall settings.

Different OSes and different setups have different configurations for proxy or firewall. You might have to tweak them so that all servers are accessible.

The first step, you need to let the phone into DFU mode.

Open the iPhone, use the USB connection to the computer, to ensure adequate power.

HOME button while holding down the power button on top of 10 seconds (until the screen goes black), and then simply release the power button and continue holding the HOME button, and then wait 15 seconds. iTunes recognizes appear, DFU mode drivers successful, but the screen is always black! then successfully entered DFU mode.

At this point, iPhone looks shut down, but in fact is a special DFU into recovery mode (Tip: At this screen, you must maintain the state of black).

The second step, open iTunes, you will be prompted detected in recovery mode an iPhone, and click OK.

Hold down the shift key and use the mouse to click on the "Restore" button, a window pops up to select the firmware release the Shift key to select the official firmware.
