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

I had this issue with an iPhone 15 whilst doing a restore using Apple Devices on a PC after I forgot the passcode to the phone. After going through this thread and macobserver, I finally successfully restored the phone by doing the following:

1. connected my PC to a hotspot from another phone
2. restart Apple Devices
3. forced restart on my iphone and connected the phone to my PC using a usb-c to usb-a cable (the usb-c to usb-c that came with the phone does work for the restore as at this post)
4. Followed the restore prompt instructions on Apple Devices
5. With a lot of prayers after more than 7 attempts, the restore was successful and I can now use my iPhone

I wasn't able to use iTunes as suggested by others; it didn't give me the restore/update option.

Hope this helps someone that like me, switch off when instructions start to get a bit technical.

Error code (1109).06B4.0000 on restore & (75).067E.004B on update--issues with Iphone 12 to install 18.2.1 IOS update. I was using Apple devices on window 11 to install. The install would fail many times. I changed to my other PC with windows 10- issue fixed and IOS updated using windows 10 version and Apple Device app on PC! I did restore vs. update. Hope this works for others.

Yes.. this method worked for me for restoring ipad 10.. I had exact same errors 1109 & then later -75.. don't know why Apple has messed up 18.3 restore files.. Also Apple devices app from Microsoft store is not very helpful.. this 3U application is far better to restore Apple devices such as iPad.. I had exact same errors 1109 & then later -75..

After doing Quick Flash & selected restore Battery option, things worked like a charm..

Thanks a lot for posting this method..

Yes.. one of the reason why I had restore the iPad was because for some reason iPad did not recognize the 6 digit code which I had set up previously.. I was using my ipad after a break of 1 month.. did that somehow made iPad forget my code? I do not know.. I have set up same code again.. at least this time it is working... lets see..

Thanks a lot for posting above method

Thanks for this! I tried multiple times using the Apple Devices app and kept getting stuck at 50%. ITunes wasn't recognizing the phone at all initially. I uninstalled and re-installed ITunes and was finally able to do a full restore!!

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

Remember those old Lightning to USB-A cables? Use it. Save hours

THIS WORKED FOR ME: I changed my PC's internet connection to a mobile hotspot from another phone. That's all it took! I have been working on this for the better part of 2 days.

Mobile hotspot with Apple Devices on my W11 PC alone did not fix the issue.

What did work for me was this:

Remove the SIM card, Connect to Hotspot on PC. Download/Launch Apple Devices, Enter iPhone into DFU mode (Volume up, Volume down, Hold side button until screen goes black) and then select Update/Restore in Apple Devices once the iPhone is detected.

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

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.

Thanks! Solved my problem while trying to update iPad 8th gen via Windows pc. Received the same error, so I disconnected Pc from the WiFi and connected it to my mobile hotspot and started the update again and it went smoothly.

downloaded an update via my windows laptop using the apple devices app. it bricked my ipad. upon attempting to update it, I got an uunnamed error. attempted to restore my data (which by the way, will completely wipe out years worth of information). restoration process got stuck halfway through. got error (1109) 06B4.000. restarted my computer, restarted my ipad, attempted again. nothing. turning off my firewall fixed it.

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.

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