Receiving an error code (1109) in the middle of the restore on iPhone 11

After trying 3 different computers with the newest Windows 11 Pro 24H2 and NO result in restoring my iPhone 13 Pro, I tried on an old Asus PC with the latest Windows 10 Pro 22H2.

None of the 3 PC´s with 24H2 were able to do the job, they all ended with error 1109!

The old stationary Asus with an Intel E8400 processor from year 2008 and Windows 10 Pro 22H2 did the job flawlessly.

I was running into this issue as well, I tried with separate Windows 11 machines using the Apple Devices application and it gave me errors, (1109).06B4.0000 and (4017).0648.0000. Thinking it was a network or an Intune configuration I tried hotspot and a personal Windows 11 device and nothing. It only worked on a test Windows 10 machine so I think it might be some incompatibility with a Windows 11 update or something. Thank you, community, for the different ideas and possible solutions.

I had the same problem (both on an iPhone (iPhone 12) and an iPad (iPad 8th generation)), I used different computers but I could not solve it.

When we talked to Apple Support, they asked me to do / did not check the following;

1. The PC you are using must be Windows 10 and above,

2. The latest version of iTunes or the Apple Devices application must be installed and you must do this installation from the official Microsoft Store application,

3. There should be no restrictions on the Internet connection you are using and there should be no additional protocols such as VPN,

4. The cable you are using must be an original Apple cable.

I tried everything written above completely and on three different PCs, but I kept getting the error.

The error occurs in two different ways,

1. If you do it in iTunes, the restore starts and after a while iTunes suddenly closes; the process stops.

2. If you do it in the Apple Devices application, the restore starts and after a while it gives this error; the process stops.

After experiencing this several times, I decided to do this process on a Mac as a last resort and completed the process on Mac without any problems.

I think this problem is currently caused by a bug in Windows computers accessing Apple servers or writing data to Apple devices, and this may also be related to the latest iOS / iPadOS.

If you continue to experience this problem, I recommend using a Mac computer for the fastest and most accurate solution.

I hope it was helpful.

Thank you for solving this mystery. Changing the DNS to Google (8.8.8.8 / 8.8.4.4) worked for me. I have Spectrum as Internet provider and was using Open DNS owned by Cisco 208.67.222.222 and secondary 208.67.220.220. iPad 7th gen was stuck on restore. Initially was stuck on apple logo during update over PC.

I had the same issue when updating to 18.3.1. It would close down ITunes on my PC. Updated to Apple Devices for Windows. That worked a little better but still failed. I got the (1109) 06B4.000 error. I hooked by IPhone to my work MAC and it was able to finally perform the update all the way through. I had backed up my IPhone prior to performing the update and was able to use Apple Devices to Restore from the Backup. This seems to be a Windows Issue with the new update. I don't recommend downloading via your PC until Apple figures out this bug.

Had same problem updating iPhone 12 to iOS 18.4, which I had to do via Windows Apple Devices as there wasn't enough storage on my phone and I don't have a Mac.

Tried the Hotspot and VPN tricks, but neither worked.

Spoke to Apple Support who basically said take it to my nearest Apple Store (over an hour away!)

Then I saw a post about 3uTools so last ditch attempt I tried that - and the Quick Flash thing worked, reset the phone back to factory settings with iOS 18.4, and now I am currently restoring it to a previous iCloud backup. (by the way, didn't need to do the "fix battery health" thing)

So far, looks promising - the phone is on and working, at least! Before it was completely stuck mid install, and even hard reset just took it back to same "plug me in" screen, which then got stuck again when I did.

I was then super paranoid that the 3uTools was a scam and when I was putting in my phone password to unlock it, it was actually harvesting that password along with all the others - but that was after reading one bad review amongst many good ones.

Anyway, thank you to 3uTools and thanks to agcb256 for suggesting it!

P.S. I've just found the only article I could see on Apple Support that actually references that error code 1109:

If you see Error 3194, Error 1109 or other network connectivity errors when restoring your iPhone or iPad – Apple Support (UK)

I had an identical problem while restoring my iphone 11 Pro. Got the error 1109 multiple times and it would hang in between the restore process. I was using Apple Devices app on Windows 11 Business. I tried using the suggestion from one of the users here of switching from Wifi to Mobile hotspot. But it did not work. Finally uninstalling Apple Devices and using the iTunes app on Windows allowed me to restore my iPhone.

Definetely YES! It seems to be a ISP related issue. I used a VPN service connecting to USA and everything worked like a charm. This is surely a ISP-Networking-Windows-AppleDevicesApp related issue.

Apple should investigate on it.

My affected connection is a Japanese home 5G by Softbank

It's happened in my iPad 8th Gen 32GB twice. From 18.4->18.4.1 and from 18.4.1->18.5

Windows 11 laptop: OS and AppleDevices app fully updated.

Another workaround I've found that worked was using a VPN to update the iPhone using Apple Devices.

In my case, I used PIA (Private Internet Access) on my Windows 11 PC and reattempted to update my iPhone 15 Pro to 18.1, after that never once saw any error code appear, especially the 1109 error while the update was installing.

I figured this would be useful for folks that don't have a Wi-Fi Hot-Spot available to them to connect to to work around this silly issue.

My ISP is Xfinity and I'm wondering if other folks are using Xfinity as well while encountering this error.

I hope this helps

We encountered this exact issue yesterday. My partner locked herself out of her iPhone 13, and we encountered error 1109 about halfway through the restore.

Mobile signal coverage is terrible where we live (rural England) so we couldn't try the hotspot method.

We tried:

VPN - It didn't work.

via iTunes - It didn't recognise the device.

via Apple Devices - Recognised but errored at halfway.

Eventually, I changed the DNS to Google (8.8.8.8 / 8.8.4.4) and tried again... and it worked.

I have no idea whether or not changing the DNS solved it or it if was just plain dumb luck but this did it.

So final working method for us was:

Windows 11

USB A to Lightning (non-official cable)

Connected via WiFi

VPN Off

DNS to 8.8.8.8 / 8.8.4.4

So after 4 hours of messing around it was finally done.

Apple, you guys are awesome, but this whole process is terrible and seems to be affecting so many users, ya need to do better.

I tried all the suggestions here, but what solved it for me was simply taking it to an Apple store and they re-did the update using one of their Mac laptops. From the restore screen they were able to update it to the next version and keep all my data with no problem or errors. They said this error could be a random hardware issue like a loose wire in the USB cable or jack, but they weren't sure and Apple support had no info on it. If you're not near a store, maybe try updating using another PC in your home or a friend or employer's computer.

I can confirm using vpn did resolve the issue for me as others suggested. however, i did delete the ipsw file so it would instead download via vpn.

logs are created and appended here if installed from windows store. if installed outside of the store, the logs will be in a folder nearby the ipsw so just search that.

"C:\Users\<user>\AppData\Local\Packages\AppleInc.AppleDevices_nzyj5cx40ttqa\LocalCache\Roaming\Apple\AMPDevicesAgent\iPad Updater Logs\iPadUpdater.log"

the logs indeed indicate a network issue as others have suggested but I did not find any clue as to what specifically.

I encountered the same issue on my Windows 11 Pro using Apple Devices. I got the 1109 error with a 130A.0000. After reading these posts with everyone trying VPNs and HotSpots I thought I may have an issue with my firewall. I have Norton 360 installed so I disabled my "Smart" Firewall for an hour to get through the process. That worked for me.

I got this same error code, while updating my se 3rd gen via apple devices on windows 11.

I contacted support after installing, uninstalling, attempting to cycle it, attempting to reset it, restarting my laptop, etc. All told I cycled through all the steps about 10 times. each time it hung at the halfway point. Then I reset router, which also didn't do anything.

changed the dns settings as discussed in this thread to 8.8.8.8/8.8.4.4

cycled power, restarted the restore. no dice.

connected to vpn, kept the dns settings as above.

cycled again,

restore completed.

Took me a few hours, but the vpn was the fix.

I resolved the issue by changing my DNS to Google (8.8.8.8 / 8.8.4.4) thanks to 'Fyrstars' comment on this thread. I was trying to restore an Ipad and it kept giving me error code 1109.

I closed Apple Devices app and changed my DNS then reopened the app and tried again and it failed first but worked on the second try. It could be coincidence but it failed about 10 times before I changed the DNS so worth giving that a go if your struggling.

Thanks!
