Firmware Update

Step 1. First and foremost, you’ll need the iOS 7.1.2 firmware file specific to your device.Download iOS 7.1.2 IPSW from here or ios 8.1.3 download.

Step 2. Next, connect your device to your computer, and fire up iTunes.

Step 3. Select your iOS device from the pane on the left hand side, and hold down the left SHIFT (PC) or Alt/Option (Mac) button while hitting the ‘Restore’ button.

Step 4. Browse to your iOS firmware file downloaded in Step 1.

Step 5. Follow the steps to restore your device back to factory settings. This will delete the contents of your device, hence the importance of backing up.

Step 6. The restore process can take anywhere from a couple of minutes to around half an hour, depending on the age of your device and the speed of your computer rig.

And there you have it. Your iOS device will be running iOS 7.1.2, meaning it’ll be jailbreakable via Pangu’s tool, and given that Apple won’t be signing iOS 7.1.2 for much longer, we cannot stress enough how swift you’ll need to be if you want to retain the old software.

Given the major changes Apple has made to iOS 8, most will be happy to stick with what they have, but with iPhone 4s users having encountered many glitches since updating, these steps offer perhaps the only immediate opt-out solution while Apple’s servers are still signing the older firmware.
