I’m not sure why one would want to do that, but here is a friendly public service announcement to let you know that you can still downgrade to iOS 8.1.1 should you choose to. Following the release of iOS 8.1.2 yesterday, Apple still hasn’t closed the signing window of iOS 8.1.1, which means that if for some reason you have issues with iOS 8.1.2, you can still downgrade to iOS 8.1.1 and enjoy a stable jailbreak with TaiG. 

As always when downgrading, time is of the essence as Apple could close the signing window at any time, making going back to a iOS 8.1.1 impossible.

Again, I don’t think there is any compelling argument to downgrade to iOS 8.1.1, but at least you know it is possible.

How to downgrade to iOS 8.1.1

Step 1: Download the iOS 8.1.1 firmware for your device from our download page.

Step 2: Plug your device to your computer via the USB cable. Hold the Alt/Option key (Shift key if you’re on Windows) while clicking on the Restore option in iTunes.

Step 3: A window will pop up allowing you to choose the firmware you want to restore to. Choose the iOS 8.1.1 firmware you downloaded in step 1.

Step 4: iTunes will downgrade your firmware back to iOS 8.1.1, assuming that iOS 8.1 is still being signed by Apple. If it’s not, you will receive an error message and the downgrade will halt.

        For those planning to Jailbreak on iOS 8.1.2 then I highly recommend adding this Cydia Source into Cydia after you jailbreak so you don’t have to manually input all those Cydia Sources manually. This will automatically add all the best Cydia Sources and give you access to all the best Cydia Tweaks, Themes and Apps for FREE with just a push of a button. Follow the steps below.

        1. Open Cydia

        2. Tap Sources

        3. Tap Edit

        4. Tap Add

        5. Type this url in the box (cydiasource,n e t) without the spaces and replace coma for a dot in the url.

        6. Tap “Add Source”

        7. Install the package labelled “All Sources”.

        This will give you all the best Cydia Sources to have access to all the best Tweaks, Apps and Themes for FREE..

      same error here. I don’t think it’s something wrong at your end.

      • RomanReigns

        maybe just need to restore for goddamn ringtone bug to fix the “size mismatch” issue :/

    • Sebastián Junca 

      Just reboot your device and try again. Worked for me. Good luck!

      • RomanReigns

        still doesn’t work

    • Tim

      You need to refresh your sources and wait for cydia to finish loading then you can update

      • RomanReigns

        did everything mate but still same

    • Rowan09

      Just need to delete a source from the sources page. Delete the 666repo, I forgot the name since it’s used to unlock the older phone models.

  • markelite

    I don’t think it would be wise to downgrade as long as the latest firmware is jailbreakable.

    • Tell that to people who are still on iOS 7.1.2.

      • Andrew

        All my devices are on 8.1 (soon 8.1.2 when I have time), except for my iPad 2, which is still on 7.1.2. I’d rather have an iPad that doesn’t slow to a crawl than the handful of features provided in upgrading.

  • Why would you downgrade if TaiG updated their tool to support iOS 8.1.2?

  • pauleebe

    Good guide. But there’s no point to be on 8.1.1 versus 8.1.2 since they are both jailbreak-able.

  • Jerry

    Honestly I uograded to 8.1.2 my iPhone 6 plus feels snappier & my battery has been great. I think it finally fixed my battery problem

    • h4nd0fg0d

      Word on the battery issue. +1

  • iTw3aks

    Jailbreak available for iOS 8.1.2 so no need to downgrade.

  • h4nd0fg0d

    My battery life on 8.1.2 is way better than it was on 8.1.1, but nowhere near what it was on 8.1.
