iOS 10.3.1 jailbreak: How to prepare for its release Pangu-Download.net

Pangu team recently showcased a jailbroken iPhone 7 running iOS 10.3.1 in an alleged teaser image, indicating the likely release of its latest jailbreak in the next few days. Furthermore, speculation is rife that the Pangu jailbreak for iOS 10.3.1 will be releasing sometime next week.

Presuming the rumour could actually come true, here's a simple guide to prepare for the latest jailbreak release:

Backup data via iTunes

It is always a safe bet to backup important user data on your iPhone/iPad before embarking on a jailbreaking spree, especially with the initial beta releases for jailbreaking the latest iOS firmware.

Just connect your device to computer via iTunes and you can perform a full backup of all stored data, so that it can be restored if something goes wrong.

Update to iOS 10.3.1 if running iOS 10.2.1

The public version of Yalu jailbreak is compatible only with iOS 10.2 or older iOS 10 versions and hence it is imperative that you upgrade to iOS 10.3.1 if you are running unsupported firmware like iOS 10.2.1.

Consequently, those who are already jailbroken on iOS 10.2 or lower are advised to wait for the arrival of iOS 10.3.1 jailbreak, before updating to the new iOS firmware. Check out the iOS 10.3.1 final IPSW download links posted here.
