For step 3, you need to launch iTunes and then head over to the summary page. On your Mac keyboard, hold down the Option/ Alt button or the Shift Key in Windows, followed by clicking on the Restore iPhone button. After this, you will notice a prompt to browse and choose the iOS 8.2 IPSW file that you downloaded. After this, you should select and open the file and start downgrading it by restoring to iOS 8.2. The entire process shouldn’t take more than a couple of minutes.
Meanwhile, with the release of iOS 8.3, a potential jailbreak designed for iOS 8.2 is already under development. TaiG indicated that iOS 8.2 jailbreak is facing a lot of difficulties but declared that they are still hopeful of releasing a jailbroken version soon. The team earlier completed the jailbreak for iOS beta 1 and 2 versions but sadly Apple was quick enough to shut off the exploits and turn the jailbreaks useless.
Apple is getting quite aggressive with its fixes as it patched a jailbreak for iOS 8.1.3, and a newer one hasn’t been created yet. After this issue, the would-be jailbreakers have refrained from updating their devices to iOS 8.2 or iOS 8.3.
Have you already updated your device to the latest iOS version? Stay tuned for more updates on iOS 8.3!
