Apple has released iOS 11.0.3 for iPhone, iPad, and iPod touch users running iOS 11. The latest small software update includes bug fixes to iOS and is therefore recommended to all users running iOS 11 on their devices.
Release notes accompanying the iOS 11.0.3 download mention the update fixes an issue here audio and haptic feedback were not working on some iPhone 7 Plus and iPhone 7 devices, and also fixes an issue where some displays were unresponsive to touch on certain iPhone 6s models screens that had been replaced from third party sourcing (perhaps related, we recommend using Apple to replace a broken iPhone screen for best results). It’s unclear if any other bugs or security fixes are included in the iOS 11.0.3 release.
Users can download and install iOS 11.0.3 using OTA with the Settings app, iTunes, or using IPSW firmware files for iOS 11.0.3 with the provided direct download links below.
Download & Install iOS 11.0.3 on iPhone and iPad
The simplest way to download and install the iOS 11.0.3 update is through the Software Update mechanism in iOS Settings. Be sure to backup your iPhone or iPad to iCloud or iTunes (or both) before beginning the software update.
Open the “Settings” app, go to “General” and then to “Software Update”, then choose “Download and Install” on iOS 11.0.3
Users can also update to iOS 11.0.3 with iTunes on a computer with the generic update mechanism, or by using IPSW files.
iOS 11.0.3 IPSW Firmware Download Links
You can download iOS 11.0.3 as IPSW firmware files directly from Apple by using the links below, using IPSW to update iOS is considered advanced and is generally not necessary for most users:
While most users should update to iOS 11 using the standard software update mechanisms within Settings app or iTunes, another more technical option is available that utilizes device-specific firmware (IPSW) to install iOS 11 onto an iPhone or iPad.
In general, usingIPSW to update iOS system software is considered advanced and is therefore only appropriate for more technically competent individuals. Nonetheless, it’s not terribly complicated and just about anyone can perform the procedure should they need to, if they follow instructions properly.
Why use IPSW to install iOS 11?
It’s important to point out that most users should just update to iOS 11 using the usual Software Update approach detailed here. But for those who use firmware, the primary reasons most individuals may use IPSW to install any new iOS versions are:
Storage considerations: You can update a storage constrained device since the firmware is not downloaded to the iPhone or iPad as it is through the Settings OTA method
Bandwidth considerations: You can download an IPSW file once from anywhere (either with higher speed internet access, or without a bandwidth cap) and then use the IPSW file to update
Updating multiple same devices: You can multiple devices compatible with the same firmware file with a single firmware, thus preventing the need to re-download the update. For example, if your household as three iPhone 7 Plus devices, a single IPSW can be used to update all three
Troubleshooting bricked devices: if an iPhone or iPad fails to properly install iOS 11 or the device is in an unusable state brought on by a failed software update (often referred to as being “bricked” because it is inoperable), you can often restore a device with IPSW via Recovery or DFU mode
There are other reasons to use IPSW as well, but we’ll assume if you’re going the route of installing iOS 11 via firmware then you already know why you’re doing so and have a compelling reason to proceed.
Updating to iOS 11 Manually with Firmware and iTunes
This walkthrough demonstrates using IPSW firmware files for updating an iPhone or iPad to iOS 11 that is operating as usual. Note that you can also use IPSW files when a device is in recovery mode or DFU mode if need be, but that is not specifically covered here.
Back up the iPhone or iPad before beginning, do not skip a device backup otherwise you may suffer permanent data loss
Download the iOS 11 IPSW file corresponding to the device you wish to update, and save it somewhere easy to find like the desktop
Launch iTunes and connect the iPhone, iPad, or iPod touch to the computer using a USB cable
Select the device in iTunes by clicking the little device icon in the iTunes
Select the IPSW firmware file by performing the following in iTunes:
Mac: OPTION + Click on the “Update” button in iTunes
Windows: SHIFT + Click on the ‘Update’ button in iTunes
Locate and select the IPSW file you downloaded earlier
Confirm that you want to install iOS 11 by choosing ‘Update’ when requested
Let iTunes update and install iOS 11 on the device
When completed, the iPhone, iPad, or iPod touch will reboot with iOS 11 successfully installed.
Regardless of whether you update to iOS 11 using IPSW as shown here, or using the simpler traditional software update methods in Settings or through iTunes, the device will be on iOS 11 and ready to go.
For most users, iOS 11 goes well and they are able to enjoy the new interesting features available in iOS 11. There are mixed reports of poor battery life after iOS 11 update, but most of those energy issues can be resolved with a few simple tips if need be.
