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

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

thanks for the solution... setting the PC DNS to 8.8.8.8 and 8.8.4.4 worked perfectly for me

HeadGeekNeo...

Yep, can confirm that changing my PC's DNS from auto (my ISP's DNS) to Google's 8.8.8.8 and 8.8.4.4 allowed the update to work as expected.

Logged out of corpo nett, connected guest wifi, with VPN off. Tried again and it worked. Cheers!

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.

The update-log was showing that:

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!!!!!

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

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.

Same issue for me.

Windows 11 Custom Built PC

Apple Devices

iPad 10th Gen

updating to 26.5

8 failed attempts. Tried Different Cables(Third Party) different port. Rebooting. I didnt realize my VPN was on when I initially tried, so I turned off the VPN, Malwarebytes, and Windows firewall. One of those things did the trick. never AGAIN!

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.
