However, many iOS users should
know that each upgrade or downgrade system will be accompanied by the
risk of data loss. Therefore, it is recommended that every iOS user have
to backup important data in order to upgrade or degrade your iOS
device, so as not to be lost when the system is upgraded or degraded.
How to Downgrade iOS 11 to iOS 10.3.3 on iPhone and iPad
Note: downgrading
iOS 11 to iOS 10.3.3 can cause data loss, including the removal of
important data or everything on your iPhone or iPad. Thus it is critical
to have a backup that is compatible with iOS 10 available before
downgrading (one should have been made prior to updating to iOS 11 in
the first place), this is because iOS 11 backups are not compatible with
iOS 10 or other prior releases. If you only have a backup for iOS 11,
then downgrading to iOS 10 may require you to update again to iOS 11 in
order to restore from that iOS 11 backup. If you don’t know what you are
doing and do not have adequate backups, do not attempt to downgrade or
you may experience permanent data loss on the iPhone or iPad.
How to Downgrade iOS 11 to iOS 10.3.3 the Easy Way
Follow these simple steps to go back to iOS 10.3.3 which is the latest stable version of iOS.
Step 1: Go the this page
to download the iOS 10.3.3 Final IPSW Links for iPhone, iPad, iPod
touch . It is a large file so it may take a few minutes to download.
Step 2: Now open iTunes and
ensure that you have the latest version. Go to iTunes > Check for
Updates and take a moment to update iTunes if you don’t have the latest
version.
Step 3: Connect the device to
the computer and put it in recovery mode. For iPhone 6 and earlier
versions press and hold the Sleep/Wake button and the Home buttons and
don’t release them until you see the Apple Logo. For iPhone 7, hold the
Sleep/Wake and Volume buttons until you see the Apple Logo.
Step 4: Once the device is in
recovery mode, a message will pop up in iTunes saying that there is a
problem with the device and give you an option to “Update” or “Restore”
the device.
Step 5: Option-Click
(Shift-Click for PC) on the “Restore” button and select the IPSW file
you downloaded in step 1 above and then click “Restore.”
Step 6: The device will restart
after the restore process is complete and you will then choose to set it
up as new or restore from a previous backup. If you have an iCloud
backup instead, simply go through the setup process until you see the
“Restore from an iCloud Backup.”
Note:
You will not be able to restore the backups you created after
installing the iOS 11 beta. Simply scroll down to choose the one you
