Downgrade iOS 9 to iOS 8.4

Apple officially released the public beta version of its latest operating system, iOS 9, earlier in the week, and invited iDevice owners to participate to use it.

Although the beta test is not open completely, to try it out, you must be in the first 100,000 users to register on the website – remember that many people want to try out the beta.

However, those of you who have updated to the public beta of iOS 9 might want to downgrade to iOS 8.4 for several reasons. It could be because the test version of the OS is stable and suffers from application incompatibility or interface errors. How can you go back to iOS 8.4, which is the only operating system issuing digital certifications? Below is the answer.

Downgrade iOS 9 Public Beta to iOS 8.4

You need:

  • An iPad or iPhone running iOS 9 public beta.
  • iOS 8.4 IPSW-file for iPad or iPhone.
  • iTunes 12.2 for Windows or Mac.

Steps needed to downgrade iOS 9 to IOS 8.4:

Step 1: Before proceeding, ensure that the latest version of iTunes is present on your device and you have iOS 8.4 IPSW file downloaded on your PC.

Step 2: Save the data’s backup copy on your iDevice using iCloud or iTunes.

Step 3: Switch off the Find my iPhone by going to Settings > iCloud > Find your iPhone.

Step 4: Launch iTunes and connect your iPad or iPhone running iOS 9 to the PC.

Step 5: Select the iDevice in the upper panel of the program.

Step 6: Put the device into DFU mode. To do this, hold down the lock button for 3 seconds, and while holding it down, press down the Home button for 10 seconds, and while holding the Home button release the lock button. Continue for 30 seconds holding the home button.

Step 7: iTunes will show a message ‘iTunes has discovered the iPhone in recovery mode. It’s necessary to restore the device using iTunes. To do this, select OK, and then hold the Alt key on Mac OS X, or the Shift key on windows, and press the restore button.

Step 8: Next, select the iOS 8.4 IPSW-file.

Step 9: Now wait before the procedure completes; the recovery lasts from 10 to 15 seconds. Certificates won’t require rolling back as iOS 9 is in beta status.

Now you can follow our guide to Jailbreak iOS 8.4 & enjoy your device.
