How To Downgrade iOS 11.2.1 On iPhone Or iPad [Tutorial]

Here’s how to downgrade iOS 11 / 11.2.1 to iOS 11.1.2 / 11.0.3 / 10.3.3 (on 6S only) on a compatible iPad, or iPod touch device.

Fortunately, if you have taken the opportunity to get up and running iOS 11.2.x, and found yourself in the middle of a desert, then you are really going to want to take the chance to get back on the faithful iOS 11.0.x or iOS 11.1.x while Apple is still signing those firmware versions. Here’s how you can do that.

Unfortunately, downgrading iOS 11.2.1 to 11.1.2 or iOS 10.3.3 is only literally been available for iPhone 6s devices. As for iOS 11 downgrade is not possible, because Apple stopped signing the firmware a few days ago. The only thing you have to note is that you can revert back to the current iOS 11.0.3 or 11.0.2. Jump into the tutorial.

Step 1: Those who have taken the opportunity to upgrade to the latest version of iTunes on your PC or Mac are fine, and if you haven’t? Then, you will also going to need to have the relevant iOS 11.0.3 IPSW file. You can get that from here: Download iOS 11.0.3 IPSW Links And OTA for iPhone, iPad, iPod touch, or here: Download iOS 11.1.2 IPSW Links And OTA Update For iPhone, iPad, iPod touch. Once you have the required file in possession for your device, continue the instructions from step 2 below.

Step 2: All you need now is to get it primed and in a position to be downgraded successfully. Launch the Settings app and navigate to iCloud > Find My iPhone and make sure to turn it off. You will need your iCloud password for this.

Note: If you forgot the iCloud password, then you are not going to update or downgrade iOS 11.1 to any supported version. As your device requires the iCloud password for Activation.

Step 3: Once done, connect the device to your PC or Mac using the normal USB cable you received with the purchase. You’ll also need to put your device into DFU or Recovery Mode.

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.

Congrats! You have successfully put your iPhone 8/8 Plus or iPhone X into DFU mode.

Step 4: Now if you are using a Mac, hold down the Option key and select the Restore iPhone… button in iTunes. If you’re using a PC then you will need to hold down the SHIFT button and select Restore iPhone…. This will then prompt you to select a relevant IPSW file from your local machine.

Step 5: Point iTunes at the iOS 11.0.3 or 11.1.2 IPSW file that you already downloaded earlier.

iTunes will continue its process of installing the firmware onto the connected device, which is essentially a downgrade from iOS 11.2.x in this instance. You will be presented with the familiar setup process on a device once it has completed.

Want to downgrade to iOS 10.3.3? As already mentioned that Apple is still signing that particular version on iPhone 6s, meaning that it is possible to downgrade to it right now on 6s running iOS 11.1 using our previous guide here: How To Downgrade iOS 11.0.3 / 11 To iOS 10.3.3 / iOS 10 [Tutorial].
