I've downloaded iOS 14 on my Windows PC with iTunes. Every time I try to update my phone, I get an error. It's also asking me these really odd questions about applying the update. I've never had iTunes ask these questions before.
After getting these odd errors, I'm taken to this webpage:
Windows, Windows 6
Download links:
For general advice see Troubleshooting issues with iTunes for Windows updates.
The steps in the second box are a guide to removing everything related to iTunes and then rebuilding it which is often a good starting point unless the symptoms indicate a more specific approach. When reinstalling right click on the downloaded setup file and use run as administrator. It may also help to temporarily disable any non-Microsoft anti-virus.
Review the other boxes and the list of support documents further down the page in case one of them applies.
The further information area has direct links to the current and recent builds in case you have problems downloading, or want to revert to an older version if the current one won't work properly for you at the moment. Links to the most recent builds are now at the bottom of the page.
Your library and device backups should be unaffected by these steps but there are links to backup and recovery advice should it be needed.

There's a very good chance you're experiencing the same error 4000 as a lot of other folks. The current work around looks to be disabling the passcode on your iPhone. After you update iOS, you can then re-enable the passcode.
I had this same problem with 14.01, 14.1 and 14.2. I wrote it all up in this thread: https://discussions.apple.com/thread/252006398.
The work around is to update via Wi-Fi, then you don't have to delete your passcode. Alternatively, put your phone into DFU mode (https://www.imore.com/how-to-iphone-ipad-dfu-mode -- I think DFU is a wildly appropriate acronym) and restore it from your iTunes backups. Takes a loooong time, especially if you have a lot of music and/or photos on your device.
Bonne chance!
Thanks, but this did not help. I still can NOT update my phone through iTunes on my Windows 10 PC. I can sync it with out any issues. I've made sure all updates are done and working, but I can not update the phone software. I could really use some help with this.
This became an issue after I updated my PC from Windows 7 to Windows 10. I use a proper Lightning cable.
I've never seen the warning about changed settings recently, and I'm pretty sure that's what is causing this issue. Anyone know how to get rid of that? It asks me about these settings that have never changed every single time I sync my phone. Syncing works fine, just can't update iOS.
I'm on the most up to date version of iTunes 12.10.10.2
iPhone 11 Pro 256 GB with iOS 14.0.1
Windows 10 (fully up to date)
Trying to update to 14.1
First I'm prompted to enter my passcode.
iTunes extracts the software.
iTunes backs up my phone
Then I get that silly "Apply Changes" warning. I've tried both "Apply" and "Don't Apply" neither makes any difference.
Then I get error 4000.
I might have to try the restore. I really like updating with my PC. It just feels so much safer, but with how this is all working out right now, I'm a little scared to do a full restore. I've lost that data once before, and I'm really nervous about it, even though I'm backed up on both the PC and iCloud.
Okay, so I did a full phone reset, using my PC to update the iPhone to iOS 14.1. I was able to use my PC to restore my phone to 14.1.
Now that iOS 14.2 is out, I STILL get error 4000 when trying to update with my PC.
Apple, please fix this!
Hi everyone,
i need your help. i have window 7,32 bit and i tunes version 12.1.3 . and just brought a new iphone 12 pro max. So i can't connect my phone to pc So when i do update of i tunes then this error comes " files shared by these updates has an invalid signature" . and some it says download it and install it manually but i can't even download this and i also try to find i tunes version 12.10.10 but i can't find it any where . so i am stuck here can't do anything so please help me.
thanks
Still having the issue even with the latest iTunes update (12.11.0.26). The problem appears to be that even though you enter the passcode to update the device the OS seems to still think it is locked, that's why disabling the passcode is the only way to avoid this error. This never used to be an issue until several months ago. I'm very surprised Apple has not fixed it yet.
I'm still having the issue also. Everything is fully updated. iTunes, Windows 10... all of it. Still Error 4000. I've given up at this point. I backup to the computer, then do the update while I'm sleeping with just the phone. It's stupid to be forced to do it their way when it's MY device, thanks Apple.
See If you can't update or restore your iPhone, iPad, or iPod touch - Apple Support. If you're trying to update using iTunes try over the air instead, or vice versa.
