Apple releases iOS 10.3.3 for iPhone, iPad, iPod users which features bug fixes and security improvements. It would be the last tiny update for iOS 10.3 before iOS 11. Though it does not bring much surprise, it fixes some problems that exist in the older iOS versions including battery improvement. Most of us can update without any problem, unfortunately, some users can’t update to iOS 10.3.3. They either hang on verifying update, or get messages saying "Unable to Install Update. An error has occurred installing iOS 10.3.3”. If you are one of these few unlucky users, please read on and get some tips to tackle this issue.
If you get the error like “Not connected to the Internet” when updating via OTA, the two things below usually help. Try and then update via OTA again
1. Resetting the Network Settings. Go to Settings > General > Reset >Tap on Reset Network Settings.
2. Change your DNS settings to 18.104.22.168 for your Wi-Fi.
You can restart your iPhone/iPad by pressing and holding both the power button and the Home buttons (volume down button for iPhone 7/7 P) and continue holding until the Apple logo appears, or using freeware ReiBoot to do it with 1 click.
Installing the update wirelessly (over the air) is more likely to fail. I will suggest you try updating your device via iTunes on computer.
Before go to iTunes for iOS update, please delete the failed iOS software update on your iPhone/iPad.
After removing the unpacked OTA from your device, follow the steps below to proceed with iTunes update.
If you come across unexpected error or stuck during installing iOS 10.3.3, ReiBoot is recommended to fix the issue without damaging your device data. The system recovery function in ReiBoot will fix any stuck like recovery mode, DFU mode, black screen, endless reboot, etc. What is more, your iPhone/iPad/iPod will be installed with the latest iOS 10.3.3 after system recovery.
Open ReiBoot, choose “Fix all iOS Stuck” and then click Fix Now.
It will detect your device and display the latest iOS firmware file for downloading.
You can download the firmware file online and wait for ReiBoot to repair the system. The whole process takes a few minutes and your device will back to normal with iOS 10.3.3 installed.
iOS 10.3.3 is available for iPhone 7/7 Plus/SE/6s/6s Plus/6/6 Plus/5s/5c/5, iPad 4th generation and later, and iPod touch 6th generation. If you are running into iOS update failure or error, just give these solutions in this article a try. My iPhone 7 Plus is now performing much better in terms of battery life after this update.comments powered by Disqus
