Unable to Install Update - iOS 9.3.5

Exactly the same problem is happening with iOS 10. Having no indication whatsoever what the problem is is not helpful.

After reinstalling the Apple Mobile Device Driver in Windows and updating iTunes, it finally detected my iPad and completed the install. I feel bad for those without a computer as there doesn't seem to be any fix for those without one.

The installer must know what the problem is and is seems just lazy not to enable it to give an error code or explanation to users.

Happy I solved my issue, but hope a more effective solution that works without needing to connect to a computer is found.

Apparently, my last comment was inappropriate. So, I'll try to be super-civil.

Thanks for the replies.

Just so that other users can use their time efficiently, I would point out that whether or not iOS 9.3.5 is currently available or not isn't relevant to to my query and and doesn't seem to be relevant to the other comment about having the same issue.

I was able to solve the problem with my iPad's iOS update (which I note was to iOS 10.0.1 in the end), by updating the Apple Mobile Device Driver in Windows 10 and installing via iTunes. In the original listing for the device in the System control panel, it stated that it was something different, I think it was 'Apple USB device/controller'.

What would be helpful to those of us who don't have computers is if anyone has any tips other than the 'restart, delete and redownload update, install via iTunes and check battery/storage levels' (that didnt work for me or some of the other people who noted they are struggling), it would be wonderful if they could share them.

If my comment is unhelpful, I personally will not take offence at someone pointing that out in a non-abusive manner. Indeed, it is only by knowing when I get something wrong that I can stop making the same mistakes.

iOS 10.1 doesn't exist yet (not as a public download anyway).

Thanks for the suggested fix, but I explained that I have now resolved my issue.

The proposed solution would not have worked though - as I mentioned, I was able to download the update directly (and note that I had done a backup), but it wouldn't install. As I also mentioned, I was only able to install the update via iTunes and as I have now updated, don't need further instructions myself.

It may be helpful to other users however if someone has tips on how to solve the problem I experienced without using a PC/Mac to share them. For example, if there is an error log somewhere that might have had useful info on the cause of the installation failure.

I won't be replying further on this thread as the last comments haven't been relevant to me.

Thanks for the reply, but this isn't relevant to the specific issue I raised.

As I noted, in my case deleting and downloading the file again did *not* help. This was stated very clearly in my original post and I asked for *different* solutions to those I had already tried.

I had said that I wouldn't reply further but felt I had to as once again, a suggested solution has been posted that appears to ignore what I stated in my query. Redownloading the update file would be a helpful suggestion for someone who hasn't tried that. Suggesting it to someone who has stated that they have tried that already is not helpful. I have no reason to believe the reply was meant to be unhelpful, so please take this response as constructive criticism aimed at all of us as something to learn from, not a personal attack.

What is valid to suggest is that future update files may not have the same problem, so it is worth trying the 'delete update file and redownload' solution when new versions of iOS are released.

As I get an email each time a reply is added, I implore other users of the forum to read what has already been said before posting further replies that aren't relevant to this specific situation - namely, that updates fail and all suggested solutions fail (other than in my case updating via iTunes). It still seems that there is no solution for those who don't have a PC/Mac, so please do add a comment if you have a *different* solution to suggest.

I hope this message does not come across as being a 'rant', I am merely trying to prevent the time of other users and me being wasted and unnecessary annoyance being caused.
