iOS 8.1.1 Update Available with Bug Fixes [IPSW Download Links]

Nov 17, 2014 - 21 Comments

iOS 8.1.1

Apple has released the final version of iOS 8.1.1 for iPhone, iPad, and iPod touch users. The iOS update is focused primarily on bug fixes and stability enhancements, though some performance improvements are also said to be included for some older hardware.

The brief download notes mention performance improvements aimed specifically at iPad 2 and iPhone 4S, suggesting other devices will likely not get a speed boost from the update. Most devices will find the iOS 8.1.1 build number to be 12B435, while the iPhone 6 devices build is 12B436.

Users can choose to install the iOS 8.1.1 update in several ways, on-device with OTA, which is recommended for most, with iTunes with the update process, or using ISPW firmware files downloaded from the links below.

Download & Install iOS 8.1.1 with OTA

The simplest way for most users to get iOS 8.1.1 is on the device through OTA updates, as a delta update the size weighs in between 65MB and 200MB, depending on the target device. Always backup your iPhone, iPad, or iPod touch before beginning any system update. You will need to be on a wi-fi connection to download the OTA update:

  1. Go to “Settings” then “General” and to “Software Update”
  2. Choose “Download and Install” to begin the process

    What is the hash file (CRC32/MD5/SHA1) of iPod5,1_8.1.1_12B435_Restore.ipsw? So i can compare if my downloaded file is not corrupted or legit.

    • tbu says:

      These IPSW files for iOS 8.1.1 are coming directly from Apple

    • rahat says:

      dont worry! it is safe
      it downloads strait from the apple software server..
      the same server itunes download your software..
      well now it depends
      .. on what type of update are you performing
      i am performing a clean update.. so that i can jailbreak..
      you also do a OTA….
      OTA update is not stable for jailbreak… :)

    Every time you post these IPSW download links, you get the CDMA and the GSM backwards on the 5S. That is how it was on 8.0, 8.1, and now 8.1.1 again! I have to click the GSM link to get the CDMA file, and I have to click the GSM link to get the CDMA file!

    I am not able to connect my iphone 4s version 8.1.0 with itunes , What should i do ?

  4. Robert Holman says:

    iPhone7,2_8.112B411_Restore.ipsw suddenly appeared in the trash bin. Cannot open or trash. Moved to Desktop, since trash won’t function with this file in it.
    Recently upgraded to iPh6 from Sprint from a Verizon iPh4. iPhone 8.1.1, MacOS 10.10.1. No problems with either, except printing from OSX10.

    What can I do?

  5. Sean says:

    Im trying to avoid getting 8.1.1. I am trying to do it from ITunes. I want to get just 8.1 version.

  6. Sean says:

    ok after you download the files where do you place it and how to you start the update in ITunes?

    • itai says:

      Sean, go to Settings > General > Software Update

      Do it on your iPhone to update to iOS 8.1.1

      Or open iTunes and click on “Update”

      You are not at a point where you should use IPSW files. Do not try.

  7. ndabbot says:

    For some reason I cannot download any ipsw, all i get is error processing request message.
    Can anyone confirm that links are actually working?

    • yes says:

      Yes of course the links work, the iOS 8.1.1 download links are direct to the firmware files on Apple servers. Just got the iPhone 6 Plus IPSW without incident.

      You may have a DNS issue or some other connection error.

  8. Peyman says:

    I downloaded iPhone 5S (CDMA) for my new iPhone 5S unlocked, but when I want to restore it with iTunes 12.0.1 it show me the error “firmware file is not compatible” ??
    what should I do ??

    • petuinia says:

      You should update with iTunes by clicking on the “Update” button, or use OTA.

      Updating with IPSW firmware is advanced stuff, not everyone can do it.

    • rahat says:

      try downloading the ipsw
      from any other site..
      or directly from itunes \
      but itunes sometines fails to download large files

  9. Leon says:

    Watch it OTA installation,
    leaves the installation image on the iphone so after succesful installation.
    there is no room on iphone an restart won’t free-up this room even if you delete all picture video’s etc. from iphone, a recover/reinstall gives room free.

  10. Leigh Barnes says:

    Hurrah! With ioS 8.1.1 my iPad 2 and iPhone 4S are both back to their former (ioS7) selves. But why does it always take Apple several goes at getting it right? Surely the “right first time philosophy” is best?

  11. chocieweb0pen0 says:

    It always drives me crazy when there is adequate free space but the updater either on the phone or in iTunes claims there isn’t enough free space. I usually have to take all of my music off, and then update.

    • vdiv says:

      Yeah, a pleasant surprise… Not sure if it is because it just rebooted the 4S and cleaned a bunch of “Other” junk.

      So far I’m happy.
