iOS 9.3.5 Security Update Released for iPhone, iPad [IPSW Downloads]

Aug 25, 2016 - 27 Comments

iOS 9.3.5 for iPhone and iPad

Apple has released iOS 9.3.5 for all compatible iPhone, iPad, and iPod touch devices. The small update appears to include important security fixes and is therefore recommended for all users to install.

Updating to iOS 9.3.5 is easy as we’ll walk through below, and advanced users can also choose to use the IPSW firmware files to update manually with iTunes if desired.

Updating to iOS 9.3.5 with OTA

Updating through the Over The Air mechanism is typically the easiest way to install a software update. Be sure to back up before installing.

  1. Back up the the iPhone, iPad, or iPod touch first
  2. Open the “Settings” app and go to “General” then choose “Software Update”
  3. When iOS 9.3.5 update appears, choose to “Download and Install” and agree to the terms of service (after carefully reading it all, obviously)

iOS 9.3.5 update

Some users are getting stuck on an “Unable to Check for Update” error popup within the Settings app when trying to get iOS 9.3.5, with the repeated “Try Again” and “Cancel” buttons not seeming to do much. If this happens to you, quit the Settings app, wait a few minutes, then try again and the update should appear.

Another option is to use iTunes to update to iOS 9.3.5, available if you connect a device to a computer with iTunes through a USB cable.

iOS 9.3.5 IPSW Direct Download Links

Some advanced users prefer to use IPSW files to update iOS system software. The firmware files are hosted by Apple servers and can be downloaded from the links below:

Don’t forget to backup your device before installing a software update, even if it is a minor point release.

    It looks like it patches three security vulnerabilities that were recently uncovered by some surveillance thing.

    Unlikely to impact most people but it is always good to secure your phone by installing software updates.

    Apple did quick work on this one, which is good. Now if only they would update any of their Macs……

  2. calciumJoe says:

    iOS 9.3.5 is pretty important to install. This patches some major web-based attacks that have been used to target people.

    A lot of details here

    Good information but you forgot to put the link for the ipsw download where you said you would. Also, checked Apple support page and they still haven’t posted info about the update

  4. Wharf Xanaduu says:

    I refuse to install these updates. They offer nothing new for me and that is all I care about!

    • Patrick M. says:

      Good for you. It’s not all about features, genius. Have you heard of this little thing called Security? I bet you don’t give it a second thought, but you’ll be one of the first to complain when your devices are compromised.

      • Luis says:

        I won’t do it either, it takes some time to update and also, the risk of bricking the device on every update has increased in recent years, making me wonder if it is worth it. Besides, apple is pushing updates too often: we just got 9.3.4 not even two weeks ago and in about the same time, ios 10 will be out. I will wait for that one instead.

        • Ikomrad says:

          It’s funny that you said this. I installed the update on my iPad Air 2 and my iPhone 6 plus today. The iPad Air updated and restarted without problem.

          My iPhone just sat at the update screen and it never installed. I did a hard reset/restore followed by an update , which worked the 2nd time.

      Precisely why you’re the biggest doofus on OSX and the internet.

    These are substantial security issues that have been patched. If someone is on iOS 9 they should update to iOS 9.3.5.

    These are not theoretical risk, these are active risks that have been utilized already by hackers.

    Update your iPhones, people.

  6. Barttels says:

    That was quick and easy. No restarts required.

  7. Phred says:

    9.3.5 magically fixed my camera. When I installed 9.3.4 my phone bricked. I did a hard reset, and my camera did not work. I tried everything to get it working.

    I just installed 9.3.5 and now my camera works!

  8. YJ says:

    Fix the links for iPhone 5 CDMA and GSM.

    The iPhone 5 GSM link points to iPhone5,3 (which is an iPhone 5c), while the iPhone 5 CDMA link points to iPhone5,1 (which is the GSM version).

  9. Ii says:

    What about iPhone4? Are older iOS also in risk?

  10. I did the lasted phone security update and always the phone is backed up. Went into to email and all was gone from inbox. Yikes!! got on my computer and the same. Did looking around and found all my messages new and old had been moved around to different folders. What the heck happened? I do I prevent this from happening again?

    • Tom Heinlein says:

      Unfortunately this is why I don’t install the updates and can’t recommend anyone install the updates from Apple anymore. There is always some problem waiting to happen, even if the smallest update. I just don’t trust the software updates anymore unless I have an entire day devoted to troubleshooting, backing up, restoring, the whole works, and who wants to spend their day off doing all that? Backing up my iPhone takes over 2 hours, and restoring my iPhone takes over 4 hours… what the??? The entire time you can’t use your phone, or your camera, or anything else… it’s as good as a stale sandwich on the counter.

      I hope Apple addresses the problems with updates soon, software quality has plummeted. The only hardware they update anymore is the iPhone and it’s half-effort, the new iPhone 7 looks more boring than anything I could dream up. Everything else is four years old. I don’t know what Apple is focusing on but it’s sure not any of their current customers or current products, and it’s not their software either. What gives? I can’t be the only one who notices this.

    • Paul says:

      Your emails may have been removed from the inbox if the iPhone is low on storage space, the latest versions of iOS delete emails automatically when the device is low on space. They then try to download again from the mail server when space is available. If you are getting a low storage warning, consider that to be a possibility.

      If the iPhone is not low on storage but you lost your emails with iOS 9.3.5 update, you may want to restore to the backup. If you made a backup beforehand of all your data you could restore the device from that backup and your emails should return as well. You can do that with iTunes or iCloud, and it can take a while to restore an iPhone. Good luck!

  11. Alex says:

    Despite it is available for iPhone 4s, iOS 9.3.5 will break the compatibility between the iPhone and iTunes 11 on Mac running Mac OS X 10.6.8 Snow Leopard.

    I discovered it by my own and now I’m paying the consequences of trusting Apple as the company it used to be some time ago.

    So if some of you have and old Mac (and you feel fine with it), DON’T UPDATE TO VERSION 9.3.5

  12. Florp says:

    Hi, what about the files for 5S? they look as if they were created from 6. On all websites I found the same issue.
    Help please?
    Thanks

    • DrDon says:

      I believe you are misinterpreting the filename of your download. The “identifier” for 5s (GSM) is 6,1. Another example – my iPadAir2 is designated iPad5.

      Look at the BACK OF YOUR PHONE/DEVICE to find the MODEL.

      Generation – common name of the device

      Model – designation on the back

      Variant – service type

      Identifier – device series and firmware update series i.d.

    I can’t get the ipsw files to open in itunes to downgrade an ipad, two days after the upgrade – what a mess apple have made of it – now you only need 6 clicks instead of 1, finger print lock doesn’t work, browser dead, icloud missing…

  14. Jan says:

    Sorry if this is a dumb question, can these files be used anytime to restore an iPhone? Or do they fall under the category where they have to be signed by Apple so they can be used?

    Thanks.

    Not Working…

    Hi,

    I have the iphone5 with iOS10.2 and itunes 12.5.4.42 and I would like to downgrade to iOS8, so I start to downgrade to iOS9 first, but when I select the file for iphone 5 (GSM or CDMA, tried both) the itunes tells me the firmeware is not compatible.. (error 1641)

    Anyone dad the same issue?

    Tanks

  16. Marc says:

    NOT WORKING
    iTunes declined my image.
    “TATSU declined to autorize this image on this device for this user.”

    “TATSU declined to autorize this image on this device for this user.”

    Me too, is there any SIGNED ipsw file still available somewhere? I am really fed up of their propaganda security updates.
