Verifying Update Failure (iOS 10.3.3)

My iPhone 6 on iOS 10.2.1 hasn't been able to update over-the-air since 10.2.1. Every time, I download the new update, go to install it (OTA), and it hangs on Verifying Update, or eventually says "Unable to Install Update. An error has occurred installing iOS 10.3.3."

Does anyone know why this may happen? Is it a lack of needed free space? Does it have anything to do with 2-factor verification on our Apple account? Does it not work on wi-fi? Does it not normally work on LTE?

I've deleted the update multiple times and re downloaded, then tried to reinstall. I've made sure I have 4 GB of free space. I've disabled 2-factor verification on my account. And I've tried both wi-fi and through my cellular data.

The only thing I've ever found that addresses this problem is when people suggest to update via iTunes. This doesn't explain why these Verification Updates don't verify correctly, nor does this solve the problem for someone who uses an iDevice independently from iTunes.

iTunes is a solid work-around, but I'd love to know how to fix the problem so it will verify an OTA update instead of constantly being told to do it another way. If OTA updates are still something Apple supports, then they should have a fix/solution to the OTA updates not working, shouldn't they? And not just a work-around, suggesting to do it a different way, which requires the customer own another piece of computing hardware. Does anyone know how to fix a "Verifying Update" or "Unable to Install Update" failure?!? Or does everyone not know, including Apple's tech employees?!?

iPhone 6, iOS 10.2.1

I tried all of the other suggestions found on other threads did not work for me.

If you are/were part of the iOS beta program delete the beta profile then shutdown/restart your phone.

A sign this is the problem is that in Settings>About>Version = 10.3.3 and the update is also showing 10.3.3

This is what I did to fix:

Settings>Storage & iCloud Usage>Manage Storage>iOS 10.3.3>Delete Update

Settings>General>Device Management>Apple iOS beta>Delete

Power cycle phone

Settings>General>Update>(New update >10.3.3 is available)

You'll see that notice if you have an out of date installer already on your phone. Try this to remove it:

Step 1: On your iPhone, iPad, or iPod touch, go to Settings > General > Storage & iCloud Usage.
Step 2: Under Storage, select Manage Storage.
Step 3: Locate the iOS software download in the list and tap on it.
Step 4: Select Delete Update, and confirm you do want to delete it.

I had a beta profile that was preventing me to update 10.3.3 and remove that profile from settings and restarted, It prompted me IOS 11.1 and I was able to install it.

Thanks, This thread was helpful

Had same issue....

SOLUTION:

remove the beta profile
reboot phone

Other solutions to reset settings might help some but not a solution really.... they might have luckily deleted the Beta profile in the process

Had the same problem. I powered off my phone and then powered it back on (because it hadn’t been rebooted for quite some time). Update was successful!

My updates stopped working at this point as well. I also tried wifi vs not wifi, hard reset, deleting update, updating via iTunes, blah blah, etc etc..

I did a reset of my phone ("erase all content and settings") restored (I back my phone up) and now it is updating to Version 11.

Hallelujah.

Did you look to see if there was a beta profile?

What version are you currently on?

Also try this:

Hold power button until the slide to power off appears.

Let go of power button

Hold down home button until the screen blinks off then comes back. This will clear the cached memory of the phone.

Worth a try.

Try plugging into your computer, turn the PC/Mac on then log in, after that open iTunes then click on the button next to the iPhone 6 picture that says Check for update once it finds iOS 11 click download & install then do the requirements but if that fails call Apple Support on 1300 321 456

If you're trying to do the update over the air, try using iTunes instead.

I appreciate you responding, but after reading that link, it makes me feel like you didn't read my original question. Or you also don't know why verifying fails or the updates are not able to be installed, and so you just sent a generic link. The info in that link does state:

"If you see an error or need more space when updating wirelessly

If you see an error message while trying to update your device wirelessly, learn what to do. If you need more space for a wireless update, you can update using iTunes or delete content manually from your device. Whether you use iTunes or update wirelessly, you'll have the same amount of free space on your device after you update.

Some iOS software updates aren't available wirelessly. VPN or proxy connections might prevent your device from contacting the iOS update servers."

Has anyone been able to update over-the-air since iOS 10.2.1? If anyone has been able to do it, why can't my phone do it? Has anyone updated to iOS 10.3.3 over-the-air? If so, I don't understand why I can't. This update was available to download over-the-air. And it asks me to install it, which leads me to believe that it is "available wirelessly."

Stupid question, but if backed up to the cloud, presumably you got all contacts back? I'm failing to see a solution more likely to work than this (unless I've missed it) on this thread
