How to Downgrade iPhone Firmware

Do you want to downgrade your iPhone or iPad to an earlier iOS version? There are several reasons why you might want to do this, but the main one is that the current iOS version is causing problems. When Apple releases a new firmware version, you get a short time in which to try it and downgrade if you need it.

Because after a set period of time, usually a week, Apple will stop signing the old firmware so you won’t be able to downgrade back to it; you’ll be stuck on the new one, problems and all!

Let’s dig in

Before Downgrading:

Before you downgrade your iOS version, you need to do three things. These will ensure that your data is safe and that you can downgrade successfully:

  • Make sure iTunes is up to date. Open iTunes and click on Help>Check for Updates. Follow the onscreen instructions to update. itunes-update-mac
  • Make sure your data is backed up. You can use iTunes and/or iCloud for this; if you don’t and something goes wrong, you will lose everything. itunes-backup
  • Disable Find My iPhone/iPad, your passcode and, if enabled, Touch ID. You can enable them all again after the downgrade. find-my-iphone-turn-off

Fix TinyUmbrella Downgrade Errors :

TinyUmbrella is a reliable app, but there are a couple of errors that you might be unlucky enough to come across – Error 1 or getting stuck in recovery mode:


  1. First, download Fix Recovery onto your computer and extract the files
  2. Download zlib.dll and save it onto your Pwnage folder
  3. Extract the contents and then follow the steps above to put your device into DFU
  4. Find the file named fixrecovery43.exe and open it
  5. Let it do its work; once finished your iOS device reboots and you can use it once more

It’s that easy.

A word of caution:

You cannot downgrade to an iOS version that Apple no longer signs. If you try, you will get an iTunes Error 3194 or one that reads, “Device Isn’t Eligible For Requested Build”.

  1. Hi, thanks for the tutorial, but ….

    I have followed the steps, however in the end the iPhone 4s finally installs iOS 9.3.6.

    I choose the downloaded file from 9.3.5 but it seems to “update” after installing it.

    I have tried disconnecting the wifi from the laptop but then it comes out that you cannot communicate with apple.

    any advice?

    Thank you

    • bad timing. Apple just released iOS 9.3.6 while also closing signing window of iOS 9.3.5 ( which was jailbreakable earlier ). So if you are looking for a jailbreak, then bad luck. You will have to wait for it before someone does it again. Downgrade back to iOS 9.3.5 is not possible, as signing from Apple has stopped.
