Numerous number of iOS devices owners will probably already be aware of that it din’t take Apple long to release updated version of iOS after the initial introduction of iOS 9.3. Made available to download iOS 9.3.1 on iPhone, iPad and iPod touch devices right now as part of Apple’s afforts to fix a unusual unverversal links bug that became apparent in the last few days.
Worth accidentally! If you’ve upgraded to this latest version, or couldn’t find anything better performance on your device post update, then you may really want to revert back to the previous version of firmware to iOS 9.2.1. But Apple stopped signing in iOS 9.2.1, now waht and how to downgrade iOS 9.3.1 to iOS 9.2.1, then?
The first thing to note here is that as of this writing, a downgrade from iOS 9.3.1 is only possible if you’re comfortable with rolling back to either iOS 9.3 or 9.2.1. Because, these two firmware versions are the only current versions of iOS that are still being digitally signed by Apple, and the only versions that an iOS device will accept restores as part of an iTunes solution. And once that signing window is closed, you can no longer downgrade back to that older firmware anytime.
Now that iOS 9.3.1 is actually available for public consumption, it won’t be long until Apple’s engineers prevent the rollbak of firmware to older iOS 9.3 or iOS 9.2.1 by actually internally stop signing those specific firmware versions.
So, those iOS device owners with an entusiastic interest in going through a jailbreak process should also be ware that it’s not that currently possible to rollback firmware to a version, like iOS 9.1, that a jailbreak solution is being offered for. Neither both the iOS 9.3, iOS 9.2.1 nor the latest iOS 9.3.1 have any kind of public jailbreak solutions being available for them.
Downgrading to an earlier available version of iOS as the real main driver. If you have taken the opportunity to accept today’s upgrade, then follow our guide on how to go through the process here.
How to downgrade iOS 9.3.1 to iOS 9.3, 9.2.1 on iPhone or iPad
First of all you have to perform a full back up of the existing device on the current firmware, before embarking on any downgrade process. Make sure that you make local backups seperately of the iTunes and iCloud backup as Apple doesn’t allow iTunes/iCloud backups made a newer firmware to be restored on older firmware.
Second point is you’ll only be able to downgrade to iOS 9.2.1 as this is the only old firmware that is being currently digitally signed by Apple.
If you’re looking to downgrade to get a jailbreak, Apple is no longer signing th last jailbreakable iOS 9.1 firmware anymore, so that’s no longer possible. On iOS 9.2.1 nor the iOS 9.3 firmware have a jailbreak solution either. Anyway, make sure that you’re using the latest version of iTunes to perform the restore.
Step 1: You’ll need the iOS 9.2.1 IPSW file that’s relevant to your particular device. You can download that device specific file from here: Download iOS 9.2.1 Final Links for iPhone, iPad, iPod touch.
Step 2: Before you enter into the restore point, there’s a little additional work needed to be undertaken on the device itself. Launch the Settings app on your device and navigate to iCloud > Find My iPhone. Make sure to disable the Find My iPhone feature.
Step 3: Connect the iPhone or iPad to your Mac or PC using the relevant sync/charge cable to that particular piece of hardware.
Step 4: Launch the latest version of iTunes on your machine. make sure that your connected device is selected, then select the Summary tab to display all information about the connected hardware.
Step 5: From this point, now you’ve done a bit of housekeeping on the phone or tablet. It’s time to actually go through the restoration process. Using a Windows system, hold down the ‘Shift’ key and click the Restore iPhone…button in iTunes. Mac users will need to hold down the ‘Option/Alt’ key at the same time as clicking the Restore iPhone…button.
Step 6: Now select the relevant iOS 9.2.1 firmware file that was downloaded as part of Step 1 when asked to locate an IPSW file. iTunes will rectify a number of prompts that form part of the restore process. Make sure you follow this through accurately and accept anything that’s relevant.
iTunes will then go thrugh the whole process of restoring the device to iOS 9.2.1. When completed successfully, the connected iPhone or iPad will reboot with a clean version of Apple’s older firmware activated.
What we recommend is it’s waste of downgrading to iOS 9.3 or iOs 9.2.1 now. There is no jailbreak solution current available for both iOS versions. Those who have considered a downgrade for jailbreak reasons only would really be better of remaining as is on iOS 9.3.1.
Update X1: Apple stopped signing iOS 9.2.1. which means you can no longer downgrade from iOS 9.3.1 to 9.2.1. iOS 9.3 is still being signed though so you can downgrade to it from 9.3.1 if you want to.
