iOS 15.7 Update Download Failed

I faced this problem as well, after trying different ways (using cellular data, on wifi, air, while charging etc) finally I could update it while my phone was 100% and still charging and I was connected to the Wi-adi. My device it’s an iPhone 11 and it could be a bug or something so I recommend to try the way that it worked for me. Cheers!

Same issue here, with iPhone 12. This via air, or plugged into a computer and iTunes. Additionally, updating to 16, still indicates a storage issue. Says I need to have at least 1.42GB, but I have 4 GB free.

Skipping the update for now.....after trying for two days!

Same problem. No help so far. Is there any help updating to iOS 15.7 in XR iPhone Keeps getter error same as above.

help !

This answer doesn't help - at all. It completely ignores the issue. The statement: "Newer models, not appearing in this list, are all able to be updated to the current version, iPadOS 15.7" simply ignores the fact that most users (me included) are operating with 'newer models' (I have an iPhone 12) and are updated to the latest iOS (which I am - 15.6.1).

The above advice 'sounds good', but again, it completely ignores the glaring issue, which is that most normal users are 'up-to-date', yet they are either getting the above error, or getting what I get - "An error occured downloading iOS 15.7" error notification:

15.7, failed over the air. Failed over WiFi. Failed while connected to a laptop, via iTunes. I noted this in my comments. Same error message as in the first post. 16 Update will not update due to a false "storage" issue. Also via all three (Air, WiFi and iTunes).

How is my reply missing the point? I have provided specific guidance within my initial reply that provides procedures to address a failing update.

So, if you can provide specific information as to which of the support documents you are following - and where the process fails - additional help may be forthcoming.

You also illustrate a screenshot for iPhone - and not iPad. While much of the guidance I have provided is generic to both iOS and iPadOS platforms, there will be differences.

Your reply missed the point by a mile. People with current platforms, indicate an issue, and you reply with a list of older platforms, that can not use IOS 15.7. Same with the other person, who said since we have iPhones, we should post that there.

The 15.7 issue is occurring to updateable IOS platforms, including iPads, iPhones, etc. The platform, is not the issue.

The goal of posting issues is for people to actually provide useful information that they can utilize to get past the problem.

If you don't have a solution....move on.

You needn’t be rude.

Experience here tells that many users often post incorrect or incomplete explanation of their issue. In posting a full answer, additional information may herein may ultimately be relevant or might be helpful. Clearly for you this is not the case, but for others searching for solutions to their own issues, may encounter the post - and find information that, for them, is helpful.

As for “moving on”, that’s up to me… not you.

So, I cordially wish you well in finding a solution to your own problem.

I was not rude at all. I explained the facts, and if you are offended by the truth, then you have some issues. The issue was clearly explained, and others (me) indicated the attempts of updating via air, WiFi, and via iTunes. This issue is across multiple current platforms.

Others have indicated they have the same issue, with IOS 15.7, and at this time no one has provided any clarity about a solution.

Your comments to date have not helped, and in fact are condescending towards those who have had the issue. Additionally, you've added nothing to this conversation other than to let us know how easily offended you are when people present factual information. Again, move along unless you have something positive and helpful to add in order to help those with the issue.

The screen shot above, is not from me. It is from another customer. Same issue, different platforms, so very relevant to the original post. If anyone has hijacked this conversation, its you.

Do you have a solution? If so, please let us know. If not, please move on.

Thank you, I'll give that a go. I restarted my iPhone once, but I will leave it off longer. Thanks for your help, and glad you have progress!

It is not my screenshot. It was provided from someone else.

I am having the same issue and I have tried wifi, cellular, and lots of frustrating moments.

Thank you, that’s normally where I operate at 3-6GB. Having an external storage device has made big help. What’s not helping is the new apps are eating way too much storage with each update.
