iOS 10.3 is now available in beta stages only and it may come with bugs and glitches. If you have updated your iPhone to iOS 10.3 and you find it unstable, it’s best that you downgrade back to iOS 10.2.1 and wait until the final release comes out.

In this guide, we will walk you through the steps to downgrade iOS 10.3 beta to iOS 10.2.1. Before we get started, make sure that you have updated your iTunes to the latest version and created a full backup of your iOS device using iCloud or iTunes, so you can restore it if in case something goes wrong during the process.

Note that you will be able to downgrade to iOS 10.2.1 only, as Apple has stopped signing the older iOS firmware files.

Steps to downgrade iOS 10.3 beta to iOS 10.2.1

Step 1: You need to download iOS 10.2.1 firmware file for your device. You can get the file here. Note that you need to download the correct firmware that responds to your model

Step 2: If you choose to download the firmware file with Safari, make sure that you have disabled auto unzip feature

Step 3: You are now supposed to put your iPhone into DFU mode. If you are now using the newest iPhone models like iPhone 7 or iPhone 7 Plus, the process of putting your device into DFU mode is a little bit different.

Step 4: Once you are done, you need to hold the Alt/Option key on your Mac. If you are now using a Windows PC, hold the Shift key. After that, click on the Restore iPhone button to proceed

Step 5: All you need to do now is to locate the iOS 10.2.1 firmware file you downloaded in the step 1. After that, click on the Restore and Update button

Step 6: Click Next and then click Agree to proceed

Step 7: Once you are done, iTunes will verify the software and start installing it onto your device. It may take a while, so make yourself a sandwich

Step 8: Once the restore process is finished, you will see the “Hello” screen on your device. You simply need to follow on-screen instructions to set up your device.

Step 9: You now can restore your iPhone from the iOS 10.2.1 backup you have made
