Apple's iOS 10.3 beta brings a number of new features and improvements, but those who don't like it can always downgrade back to iOS 10.2.1.
The most notable new addition that iOS 10.3 beta brings to the table is the Find My Airpods feature, which now comes with the Find My iPhone app. Worthy of mention is also the secret floating keyboards feature for the iPad.
However, if you've upgraded to iOS 10.3 beta and find it unstable or otherwise undesirable, here's how to downgrade to iOS 10.2.1. It's pretty easy and straightforward, so it shouldn't be too much of a hassle.
Getting Ready To Downgrade
This tutorial works for any iOS 10.3 beta version, but there are a few things to consider before proceeding with the downgrade. First of all, make sure that you have the very latest version of iTunes installed. Secondly, make a backup of your iOS device using either iTunes or iCloud so that your data is safe and ready to restore. Keep in mind that downgrading entails wiping your device clean and restoring from a compatible backup.
How To Downgrade From iOS 10.3 Beta To iOS 10.2.1
Once you've handled the prerequisites, you can proceed to downgrade. The first step is to download the proper iOS 10.2.1 IPSW file for your device. If you're not sure, check to identify your iOS device and browse the list of IPSW files until you find the right one for your device model. Once you find it, download the file and if you're using Safari, make sure that the auto unzip feature is enabled. Otherwise, renaming the .zip file as .ipsw should also do the trick.
Next up, connect your device to your PC or Mac via the Lightning cable, which should prompt iTunes to launch automatically. If it doesn't, launch it manually and let it refresh. From here on, head over to the top left corner of iTunes and click on your device, then select Restore iPhone while simultaneously holding down the Option key on Mac or the Shift key on Windows. This should trigger a pop-up window.
Browse and select the iOS 10.2.1 file you previously downloaded, then click on the Restore and Update button. You'll see some information about iOS 10.2.1, click Next and Agree.
From here on, iTunes will do the heavy lifting, verifying the software and installing it on your device. The whole process should take roughly 10 minutes, so be patient while it works its magic.
Once that's done and it successfully restores to iOS 10.2.1, you'll see the familiar "Hello" welcome screen on your iOS device. Follow the on-screen instructions to set it up, restore from the iOS 10.2.1 backup, and you're good to go. You have successfully downgraded from iOS 10.3 beta to iOS 10.2.1.
Note: If you get an error message saying "This device isn't eligible for the requested build," it means that you downloaded the wrong file for your device. Check again and download the right file, then resume the process.
