iTunes wants to update my already up-to-date iPhone

It’s not a bug. Apple patched iOS 9.2.1 to fix the error 53 issue without changing its version number; the patch will only appear when checking for updates from iTunes on a computer.

Sounds like Apple decided to forego standard Revision Integrity rules on this release, by not rev'ing the version number. Is this counter to their quality systems or are they in the mode of doing whatever they want these days? While this may seem like a small thing, it points out an alarming trend in Apple's quality control, which is being reflected in their products.

The update has a different build number, though I don't recall it off the top of my head. I believe it's what's called a slipstream update.

No, the full version on your phone is ( or was) 9.2.1(13d15). The new version in the update is 9.2.1(13d20). The update notificaction left off the build number, but it still has a different full version number that follows accepted standards.

Re: iTunes wants to update my already up-to-date iPhone

Isn't this lazy on Apple's part? Why are they okay with their customers receiving unnecessary messages about updating their OSs? I get it on both my iPhone and iPad. Seems sloppy to me.

😕

What unnecessary message are you talking about? The message is accurate - there is a new build of iOS 9.2.1 that is absolutely mandatory if you have received an error 53 message, and a good idea if you haven't received such a message, because if you ever do and you haven't installed the update it will brick your phone.

Here's what happens when I attach my iPhone to my iMac:

1. The following message pops-up:

A new iPhone software version (9.2.1) is available for the iPhone “Mark's iPhone”. Would you like to download it and update your iPhone now?

2. I click on "download and update". I get this message:

There are purchased items on the iPhone “Mark's iPhone” that have not been transferred to your iTunes library. You should transfer these items to your iTunes library before updating this iPhone. Are you sure you want to continue?

3. I click "Contunue". I get this message:

iOS 9.2.1

This update contains security updates and bug fixes including a fix for an issue that could prevent the completion of app installation when using an MDM server.

For information on the security content of this update, please visit this website:

4. I click "Next" and "Agree". I get this message:

Enter the passcode on “Mark's iPhone” to continue this iOS update.

5. I unlock my iPhone. I get this message:

There was a problem downloading the software for the iPhone "Mark's iPhone". An unknown error occurred (1671).

I get this all the time. Maybe its a problem with the OS X beta. I'm running.

Thanks for your response to my email.

The beta shouldn't be an issue, but it's at least a possibility. Do you have the OS X firewall enabled? If you do try temporarily disabling it. Most of the other causes of that error involve jailbroken phones, or using a computer that was used to jailbreak an iOS device in the past. I'm assuming this doesn't apply to you.

Thanks for your continued feedback. I finally got both my iPhone and iPad updated. Everything is great. I have to admit this particular upgrade seemed to be a little bit more difficult than previous ones. It was hard to know that the upgrades were actually downloading.

I have this error as well. How did you ever get your iPhone to update?

1. I decided to be patient.

2. Closed all apps on my iPhone and iMac.

3. Turned both my iPhone and iMac off.

4. Plugged my iPhone into my iMac via USB.

5. Turned on my iMac, which also turned on my iPhone.

6. Followed the iTunes prompts until no more prompts.

7. Left for about 30 minutes and followed any new prompts.

Thanks for the explanation....I had this happen on both my iPhone & iPad. Just wish Apple would have given me a heads-up.

I agree they should have explained it better. There have been a lot of questions about it.
