With a on the horizon, a number of iPhone and iPad users must be looking for a way to downgrade back to the OS from iOS 11.4. While iOS 11.4 introduces AirPlay 2 and other audio-related improvements, I am sure iPhone owners who follow the jailbreaking scene closely would be ready to give up on these features for jailbreaking their device. Apple is currently signing the iOS 11.3.1 release which means its the perfect time for you to downgrade back to it from iOS 11.4. In case, the release of the iOS 11.3.1 jailbreak is delayed or you change your mind about jailbreaking your iPhone, you can always upgrade back to iOS 11.4.

However, once Apple closes the iOS 11.3.1 signing window, the downgrading process would become next to impossible. Pre-requisites Since Apple has stopped signing iOS releases prior to iOS 11.3.1, you will not be able to downgrade to a version lower than that. If you are on a lower version of iOS 11, my recommendation would be that you stick to it for now.

There are two different ways for you to downgrade your iPhone or iPad to iOS 11.3.1 from iOS 11.4. One of them will retain your user data, while the other will wipe your device completely clean. Irrespective of which method you follow, make sure to first check that Apple is signing the firmware file.

Method 1 This is a riskier method, but it allows you to downgrade from iOS 11.4 to iOS 11.3.1 without losing data. It is also much faster than the second method which involves wiping your data and restoring it. How to Downgrade iOS 11.4 to iOS 11.3.1 Without Losing Data • Turn off Find my iPhone via the Settings app (Settings > iCloud > Find my iPhone).

• Download the iOS 11.3.1 firmware file for your device from our iOS firmware file download page for your iPhone, iPad or iPod touch. • • • Note: If you’re downloading the firmware file using Safari then ensure that auto unzip feature is disabled or use Chrome or Firefox. Alternatively, renaming the.zip file as.ipsw file should also work. • Connect the iOS device running iOS 11.4 to your computer. • Launch iTunes and select the iOS device from the top left corner. • Then click on Summary in the left-hand sidebar. • Hold the Alt/Option key on the Mac or Shift Key in Windows on your keyboard and click on the Check for Update option, instead of restoring.

• Select the iOS 11.3.1 ipsw firmware file you had downloaded earlier. • iTunes will inform that it will update your iOS device to iOS 11.3.1 and will verify the update with Apple. • Click Update. • iTunes should now downgrade your iOS device to iOS 11.3.1.
