Here’s how you can downgrade iOS 11.2.6 to iOS 11.2.5 on your compatible iPhone, iPad or iPod touch device the easy way.
As you all know by now that Apple released iOS 11.2.6 today to patch a critical bug which made messaging apps such as WhatsApp, Facebook Messenger,iMessage and others crash when a specific character from Indian language Telugu was sent to devices running iOS 11.2.5 or older.
Prior to today, a user running iOS 11.2.6, are able to revert back to iOS 11.2.5 through iTunes. That downgrade from iOS 11.2.6 window is alive now. While iOS 11.2.6 is an important update for those affected by the aforementioned issue, but if you upgraded and then immediately noticed issues such as poor battery life or performance, then here’s how you can go back to iOS 11.2.5.
Before that, you are notified that you can only downgrade back to iOS 11.2.5 from iOS 11.2.6 as Apple is still signing iOS 11.2.5, which is only firmware sitting beside iOS 11.2.6 and iOS 11.3 betas.
Also important here is that downgrading from iOS 11.2.6 to iOS 11.2.5 won’t give you any jailbreak benefits as iOS 11.2.5 doesn’t have any jailbreaks available for it. With that in mind, here’s how you can roll backiOS 11.2.6.
Note: Complete backups made via iTunes or iCloud on iOS 11.2.6 won’t be restorable on iOS 11.2.5 as backups aren’t backward compatible.
Step 1: Download iOS 11.2.5 from here.
Step 2: Disable Find My iPhone on your device from Settings > iCloud > Find My iPhone.
Step 3: Launch iTunes and put your device into DFU or Recovery Mode by following the instructions given below.
For iPhone 7 and iPhone 7 Plus owners
Enter DFU mode by powering down your devices as you normally would by pressing and holding the power/lock button until the slide to power off prompt appears. Slide it to turn off. Once completely turned it off, press and hold the power/lock button on the right side for about 3 seconds. With the power/lock button still pressed, press and hold the volume down button on the other side of the iPhone 7/7 Plus. Keep holding both buttons down together for approximately 10 seconds.
After 10 seconds, release the power/lock button, but make sure that you continue to keep the volume down button held down for another 5 seconds. You will see Apple Logo on the screen, or if you see the iTunes logo with Lightning cable appear on screen, then you have held the volume down button down for too long. In either instance, you will have to re-start the process again.
If you nail the timings, the display will remain all black, confirming that the device has entered into DFU mode successfully. iTunes will also confirm the same if you’re connected to that via PC or Mac.
For iPhone 8 and iPhone 8 Plus owners:
Press and hold the Side button on the device for three seconds. You should get the Apple bootup screen. With the Side button still held down press the Volume Down button and hold both buttons for a period of ten seconds. The image below shows exactly how!
The bootup screen should disappear once the system has detected that these buttons are pressed for a specific period of time. After that timing, release the Side button but continue to press the Volume Down button for an additional five seconds. iTunes should pop up an alert informing that it has found a device in Recovery mode. The iPhone 8’s screen should be entirely black at this stage.
Step 4: Once in DFU mode, hold down the Option key on the Mac keyboard and click on the Restore iPhone… button. Those of you on Windows can do same by holding down the Shift key while clicking on Restore iPhone... button. Once prompted, select the iOS 11.2.5 IPSW file, which you already downloaded in step 1.
That’s about it. Allow iTunes to go through the restore process. Once complete, you should have your device downgraded back to iOS 11.2.5.
