Using iTunes upon my Win 10 PC to update my iPhone XR to iOS 14 from its current iOS 13.7 build I receive an "error 4000" an unknown error occurred
Any ideas ?
I've tried this twice now, same issue.
iPhone XR
Same issue here with error 4000 - latest iTunes version, whether iTunes
from Apple or through the Windows Store - iPhone 11 Pro Max and iPad 6th
Gen. This has been happening for the past few update cycles. I believe
the problem lies in iTunes thinking the phone/iPad is locked, even if
you keep the screen on and enter your unlock code when asked. The only
way I have found to update using iTunes is to turn Passcode off in
settings, then it will update. Only thing is it will delete and
debit/credit cards in Wallet and you have to re-enter them. Apple really
needs to fix this.
Yes that worked for me. Then I had to out my card back. Also it ran for a couple hours! Thank you.
Just updated from 14.0.1 to 14.1 - iTunes still has the same problem upgrading. Which is not surprising since iTunes was not updated since the last time.
I had to do the same with an ota update, so to me it seems an ios14 issue, not an iTunes issue
next try with latest iTunes 12.10.10.2 and iOS 14.2 → still Error 4000
(Win 10 64bit v.20H2, iPhone XR with iOS 14.1, security suite like AV and firewall deactivated, 2 USB Ports tested)
Is that ridiculous? ITunes wants to update my phone every time I connect. So I have to remove my passcode every single time? Please.
I agree it’s very silly. Why can’t they fix this?
i think you’re right... actually keeping the iPhone unlocked by tapping the screen periodically also does not work
Correct, I tried setting the Auto-Lock to Never and that didn't work either.
Correct. I had tried that as well.
Is this similar to the problem where syncing never finishes Step 5 i let it run over 12 ours once and it wouldn't finish Step 5. If i remove the passcode will it complete?
I guess you could try doing what I did, after backing up your phone.
If you're having trouble with the latest iTunes version (which is required to update to iOS14) then you can download the previous version here: https://support.apple.com/downloads/itunes
[On your iPhone] Settings -> Software Update : Download & Install
The ipsw file is just over 5GB in size, so you will need at least that free space available on your phone.
Same issue, here. Reddit seems to be littered with the same issues.
Multiple iPhones and iPads, latest iTunes, already rebooted, tried different ports, plenty of space.
No dice...just garbage QA testing.
You should also allow us to pick the backup folder we want to use, so iTunes backups will stop dumping data on my SSD.
I manually make the move with the Mklink command.
I have found if you turn off passcode and set the lock screen to never the iphone will update on Windows. I hoped it was a one time thing but I have had to do it now with 14.0 14.0.1 and now 14.1. Then once updated I turn passcode and lock screen back on
Thanks after deactivation of passcode phone updated to IOS14
Deactivating passcode, dumps your apple wallet, that's a solution, just not a great one. I'm upgrading each device on device instead, backing up to my PC before I kick it off.
