TUTORIAL - Failsafe method to restore the current version of IOS

[VanillaLab]

Welcome to the iPadForums.net tutorial on the failsafe method to restore the current version of IOS on your device.

From time to time our iPads do get messed up and you want to get the device back up and running on the latest firmware so you have a fresh platform to start over. This guide will help you get your device restored with the latest firmware whilst avoiding most of the common iTunes errors along the way.



1. Update iTunes to the latest version
If you are going to install the current version of IOS reliably, make sure you are running the latest version of iTunes. Use the "Check for updates..." menu item in iTunes.

To restore 7.x IOS you must be on at least iTunes 11.1 or newer...

2. Fix Hosts File ( this step is normally for jailbreakers only to resolve error 3194)
If you are absolutely SURE that nobody that has used the PC you will be using will have ever messed with the hosts file, or jailbroken a device on the PC you are using, then you can probably skip this step only, but you MUST continue with all other steps. If in doubt, or you are getting Error 3194 you should do this step.

Lots of iPad owners mess with their hosts file but don't really understand the changes that have been made or why they made them.
Usually, the hosts file is changed to allow an older firmware to be installed by using SHSH Blobs from Cydia. Having a hosts file which is pointing towards Cydia and not Apple is probably the number one cause of issues when trying to restore a device. Normally, this gives an iTunes Error 3194. To make sure your hosts file is pointing back to Apple, follow this process:

• Download the latest version of TinyUmbrella from here - The Firmware Umbrella - TinyUmbrella
• Once downloaded, start the TU program
• Switch to the "Advanced" tab
• UNTICK the option which says "Set Hosts to Cydia on Exit"
• Close TinyUmbrella - We will not use this application again during this process, so make sure it is closed.

Alternatively, if you know what the "hosts" file is and how to edit it manually, remove ALL references to gs.apple.com from the file and save it.

• On Windows the hosts file can be found in: C:\Windows\System32\drivers\etc\hosts
• On OSX the hosts file lives in /private/etc/hosts

When editing the hosts file in Windows, you may need to use Explorer to show both hidden & system files and then launch your editor (e.g. Notepad) with Administrator privileges by right clicking on it and choosing "Run as Administrator", otherwise you won't be able to edit and save the file.

3. Download the IOS firmware IPSW file to your desktop
iTunes is not very forgiving when it comes to unreliable internet connections or times when the download servers are being put under a lot of strain, e.g. when a new firmware is released. Therefore, it is usually best to download the firmware file directly to your desktop and then direct iTunes to use it.

If you are using Windows and Internet Explorer, make sure you rename the file back to have an extension of IPSW if it gets renamed with ZIP. This is a fault of Windows and IE, and nothing to do with Apple! You could also consider using a better browser such as Chrome or Firefox to avoid this issue altogether...

4. Put your device into DFU mode
Restoring a device by just connecting it to iTunes and pressing restore will only work if the iPad is working properly. Invariably, and especially if you are looking at this post, something has gone wrong before you got here, so it is unlikely that a normal restore will work. In order to get the restore to complete normally, you MUST put your device into DFU mode.

In order to put your device into DFU mode, with the iPad connected to your computer and turned on, you must press the "home" and "power" buttons together for EXACTLY 10 seconds at which point you must release "power" but continue to hold "home". After about 15 seconds, the device will enter DFU mode.

Once your device is in DFU mode the screen should be blank. If anything else is showing on the screen, such as the "connect to iTunes" logo, you got it wrong. You must get the device into DFU mode successfully. Don't be tempted to release the button when the screen goes blank at the 7 second mark. You must hold the buttons for exactly 10 seconds! Try again

5. Temporarily Disable 3rd Party Tools
Sometimes, 3rd party apps such as firewalls, anti-viruns, and anti-malware software can interfere with the restore process, particularly on Windows. If you are having trouble with 15xx and 16xx errors this is often the cause. It's best to temporarily disable all these on your PC whilst you carry out the restore. VMWare services have been know to interfere with a restore too. Disable everything you possibly can!

6. Manually restore in iTunes
Finally, you are ready to restore your device using the firmware you downloaded in Step 3. Make sure it has completed the download of course!

Open iTunes and it should report that it has discovered a device in recovery mode and must restore it. Good! That's exactly what we want. Click the OK button to dismiss the dialogue box.

Now you must Shift-Restore (Windows) or Option-Restore (OSX) to select the firmware you downloaded. This means you must hold down the shift key (on Windows) or the option key (on OSX) on your keyboard whilst clicking the "Restore" button in iTunes with your mouse. If you do this correctly, an Explorer or Finder window will pop up and allow you to navigate to the firmware file you downloaded in Step 3. Find the file and choose it for the restore.

Done! iTunes should now restore your firmware file on your iPad without any errors.

If you run into problems make sure you followed all the steps correctly and also check you are not connecting via a USB Hub. Always connect directly to your PC. Try a different USB port and if possible a different cable, particularly if you are not using the original cable that came with your iPad. Yes, not all cables are the same, even official ones, and iPhone cables can cause problems sometimes!
If it still fails after this, post details of the error message and we'll see if we can help.

Any comments or suggestions on how to make the process even more failsafe are welcome

My Aunt was having trouble with her iPad2 (5 years old) and online help said it needed an update. She does not have a computer, so I used mine. I backed it up first then accepted the update in iTunes from 4.3.3 to 9.2. It almost finished and I got the 9 error. I then tried to restore it to factory settings and got the same error. I have tried multiple USB cords and ports. The iPad is stuck on the connect to iTunes screen. I followed your steps (minus 2 - never been jailbreaked). The message I got was: ...could not be restored because firmware file is not compatible. Help?

There's a bug in the update system that will not allow you to update from below iOS 5 to the latest version of iOS. From what I've seen, there doesn't appear to be a workaround. If you live close enough to an Apple Store, the Genius Bar may be able to help.

Hi folks,

Not sure if this thread is still going. I have an iPad 2 which has never been jailbroken. After updating to 9.3.3 the iPad gave up. I have tried restoring it in iTunes which downloads the recovery update, extracts the software but then is constantly stuck on "Waiting for iPad". I've left the iPad on overnight but to no avail.

I have also downloaded the 9.3.3 ipsw. iTunes acknowledges that it is the correct firmware but also I am stuck on "Waiting for iPad" again after extracting it. I've even disabled the firewall incase that was holding it up.

Can someone put me out of my misery and confirm that it's knackered and that there's nothing I can do? I have tried everything I can think of. If only I could put IOS8 on it, the last time it worked well.

Any help would be appreciated.

Hi, Tank Top!

It's not possible to revert to iOS 8, because it's not signed by Apple any more. Sorry!

Do you get any errors, or is iTunes just stuck on "Waiting for iPad"?

The tutorial in the very first post of this thread should help getting your iPad up to date. Give it a try, in case you haven't tried it yet. The most recent software for your device is 9.3.4, but 9.3.3 is still signed by Apple, so you'll be able to install that as well.

If the tutorial doesn't help, visit the next Apple Retail Store, let the specialists there take a look at your device. They can tell you exactly whether or not your iPad still can be used.

Thanks for the response. I have been through the tutorial but no dice unfortunately.

I've an appointment with a "Genius" next week. I'll leave it to them to tell all is lost officially. I suspect it's a hardware issue somewhere.

 

[J. A.]

That's quite possible.

How did it go with the Apple Genius, did you manage to get things sorted? In most cases like this, DFU mode is the first place to try, as long as your backed up or are willing to lose unsaved data.

I am getting a TATSU response. Please help thanks

That means there's a problem in connecting to the Apple signing server or the iOS version you're trying to install is incompatible with the device you're trying to install it on.

Do you have a good WiFi connection?

Yes. I have an iPad air 2 and it keeps stopping at the firmware part. I have followed these directions and got the tatsu message.
the pad just went into recovery mode for no reason and I am having trouble getting it out. I have tried several different things to fix this problem.

Also I Have downloaded the latest firmware and it still gives me the error 56 message at the firmware spot lol.

Error 56 means there could be hardware issues.

Make sure iTunes is up to date. The latest version is 12.5.4.

Make sure your cable is reliable (no damage).

If nothing helps solving your problem, contact Apple Support.

If you still have no luck, and you live close enough to an Apple Store, then you should take in your iPad for a Genius Bar diagnostic. Bring the cable you're using as well.
