How To Downgrade iOS 11.3.1 On iPhone, iPad, iPod touch [Guide]

As you all know by now that Apple released iOS 11.3.1 into the public domain. The release, however, means that owners of a compatible iPhone, iPad, or iPod touch now have the ability to directly update to iOS 11.3.1 as an over-the-air installation.

There is no need to downgrade new iOS version to the old firmware, that too if you are not interested in iOS 11.3.1 jailbreak, which is in the cards. While the previous iOS 11.3 has it already. It’s likely that a fairly substantial subset of device owners have already done exactly that. But, what if you are one of those who are now regretting that decision and wants to roll back the firmware to iOS 11.3? Well, Apple is still signing iOS 11.3, here’s how you can do it.

Note: Be aware that if you have updated to iOS 11.3.1 and took a backup of that device via iTunes or iCloud, then that backup will not be restorable anyway, once it’s rolled back to iOS 11.3. Backups aren’t backward compatible.

Step 1: First of all, download iOS 11.3 firmware file for your iPhone, iPad, or iPod touch from here.

Step 2: Disable Find My iPhone on your device from Settings > iCloud > Find My iPhone.

Step 3: Launch iTunes and put your device into DFU or Recovery Mode by following the instructions given below.

For iPhone 7 and iPhone 7 Plus owners

Enter DFU mode by powering down your devices as you normally would by pressing and holding the power/lock button until the slide to power off prompt appears. Slide it to turn off. Once completely turned it off, press and hold the power/lock button on the right side for about 3 seconds. With the power/lock button still pressed, press and hold the volume down button on the other side of the iPhone 7/7 Plus. Keep holding both buttons down together for approximately 10 seconds.

After 10 seconds, release the power/lock button, but make sure that you continue to keep the volume down button held down for another 5 seconds. You will see Apple Logo on the screen, or if you see the iTunes logo with Lightning cable appear on screen, then you have held the volume down button down for too long. In either instance, you will have to re-start the process again.

If you nail the timings, the display will remain all black, confirming that the device has entered into DFU mode successfully. iTunes will also confirm the same if you’re connected to that via PC or Mac.

For iPhone 8 and iPhone 8 Plus owners:

Press and hold the Side button on the device for three seconds. You should get the Apple bootup screen. With the Side button still held down press the Volume Down button and hold both buttons for a period of ten seconds. The image below shows exactly how!

The bootup screen should disappear once the system has detected that these buttons are pressed for a specific period of time. After that timing, release the Side button but continue to press the Volume Down button for an additional five seconds. iTunes should pop up an alert informing that it has found a device in Recovery mode. The iPhone 8’s screen should be entirely black at this stage.

Once in DFU mode, hold down the Option key on the Mac keyboard and click on the Restore iPhone… button. Those of you on Windows can do same by holding down the Shift key while clicking on Restore iPhone... button. Once prompted, select the iOS 11.3 IPSW file, which you already downloaded earlier.

Finally, iTunes will work its magic and restore to iOS 11.3 as requested. Once done, you’ll be all set to either restore from a compatible iTunes or iCloud backup or if you prefer to set your device up fresh.
