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

I solved it by restoring it with the Apple Devices APP. But I could only do it on windows10.

THANK YOU!! This was helpful as I have Xfinity and was struggling to do a restore and I turned on VPN and then I was able to access the phone finally!!! Thought I would tell you since you pointed out the Xfinity thing, you might be on to something LOL

Okay, so I had exactly the same problem, and solved it 20 minutes ago !

I was looking on this exact forum and I'm here to confirm : 3uTools saved me !

At first I didn't wanted to try it because it's not from Apple and I was scared to make the situation worst, but then I told myself that my phone was already bricked and I would lose nothing by trying it, and OMG it worked PERFECTLY !

That's super ironic for Apple, they're so scared of this kind of software and they are so closed that they doesn't want you to use them, and yet, these same software restored my phone, what Apple couldn't do with their own softwares (iTunes, Apple Devicies...)

Edit : I use Win11

Another data point; trying to restore iOS 26 to my 15 PM. I don't have a Mac, nor do I want one. I have Linux systems and 1 Windows system (Windows 11 24H2). iTunes is pretty much useless now, replaced by Apple Devices.

I tried everything in this thread, even when it sounded silly - ie. using a VPN instead of just changing DNS; or even having to change DNS at all, for that matter. Like, what's the technical reason that needs to be done? Anyhow, Apple Devices just doesn't work for reflashing iOS from Windows, unless you're on an older version of Windows 11 or still using Windows 10. It's not a problem with the IPSW, it's a problem with the turd of an application.

The fix was to use 3uTools, as many have pointed out. Worked first time, no BS. Not sure why I need to use potentially shady 3rd party software to flash an official iOS image to my iPhone. This thread has been going for over a year. How is this still a problem? I don't know about you guys, but this kind of thing doesn't make me want a Mac more, it makes me want one less.

Using a VPN worked for me. I am from Spain and my VPN was in The Netherlands

Same thing here. ISP block Apple and switched to Hotspot using mobile data works.

I should also add, while I have had issues with restore of iOS 18.0.1 and 18.1, I have no issues restoring the same devices to iOS 17.7, which fortunately is still being signed by Apple for the moment. So there definitely seems to be a problem with iOS 18 ipsw files.

Hello world,

at me the same issue occured while restore my iPhone 15.

Due to the case of missing a different hotspot, I used the Fixppo app and did finally a iOS downgrade to version 18.2 successfully.

Thereafter I did a restore from my latest backup from the iCloud.

done and dusted

regards ;)

Hotspot didn't work, VPN didn't work, but changing my DNS servers did! This is how I did it on Windows 11:

1. goto View Network Connections
2. Right click your active network
3. Properties
4. Double click Internet Protocol Version 4
5. At the bottom, Use the following DNS server addresses:
6. Preferred DNS server: 8.8.8.8
7. Alternate DNS server: 8.8.4.4
8. Download Apple Devices from the Windows Store
9. Plug in your iPad, and restore!

Iphone 15 pro: Tenorshare ReiBoot (Windows Version) app.  

I solved with this app, after 4 hours of chat with 3 different apple team technicians.

Date and time was off. It finally hit me what was wrong after a lot of the wording was weird. It was showing that it checked tomorrow and it was up-to-date and that didn’t make any sense until now. Why everything that looks like it was scheduling an update or it said that it was up-to-date and last time it checked was tomorrow and I should’ve just realized yeah no the date and time is not set oh so no more error codes because for some reason, date and time wasn’t set automatically and it was old and I had an update software update for my Mac now I can restore my phone

I FOUND THE SOLUTION.... USE QUICK FLASH ON 3uTools!!!!!

Finally, success. If you are in AUS and using a PC.

Steps to follow after multiple failures.

1. Update your PC to latest 11
2. Use USB a-c not c-c
3. don't use wifi.
4. use an apple devise and hotspot your PC for network access.

just change the internet connection,it worked for me

This was the solution which was working for me too. Setting the DNS to 8.8.8.8 / 8.8.4.4 in the router.

Thank you very much for this hint.
