Receiving an error code (1109) in the mid…
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)
