Apple Stops Signing iOS 18.1.1, Downgrading No Longer an Option

Apple has stopped signing iOS 18.1.1, preventing iPhone users who have upgraded to iOS 18.2 from downgrading to that version of iOS. Apple released iOS 18.2 a week ago on December 11.

Apple often stops signing an older version of iOS, usually within a week or two after a new version is released. When an update is no longer signed, it can't be installed on an ‌iPhone‌ due to a server-side software verification check.

This policy encourages users to keep their operating systems up to date, ensuring they have the latest security enhancements. Apple also stopped signing iOS 17.7.2 on Wednesday.

The iOS 18.1.1 update provided important security fixes, but no other notable changes. In contrast, the iOS 18.2 update brought several new Apple Intelligence features to compatible iPhones. You can find all the details in our comprehensive guide.

Thankfully I was able to go back to iPadOS 17 on my iPad Air 4 by using an iOS 17 beta that was still being signed for some reason because it got unreasonable slow on iPadOS 18.

They actually stopped signing it since yesterday.
Fingers crossed they will release 18.2.1 soon enough to correct the blue / red mess in photos while shooting in night mode at 30 sec exposure with the stock camera app. I won't hold my breath though.

The only time I wanted to downgrade was to save some 32-bit apps and games that had no other equivalent available and the developer ghosted.

Good time to ask this question:

Does anybody know what to do when the software update gets stuck at “Update Requested…”?

I have been attempting to download and install iOS 18.2 for days. But each time I start it just gets stuck at “Update Requested…”.

I have tried all the obvious things of making sure there is enough free space (have over 12GB of free space). I’ve tired to turn my phone off and back on. I’ve tried to “Update Now” and “Update Tonight”. I’ve tried to let the “Automatic Updates” do its thing at night or such. I’ve also turned off Automatic Updates.

It’s been days of this! Lol. Except for this update problem, my phone doesn’t seem to be having any issues. Everything else seems fine.

The only other obvious thing I haven’t yet tried is to erase my iPhone and restore from a backup. That would, of course, be the last thing I would want to attempt. Does anybody have any other ideas of what I could do (before I try to erase and restore)?
See if there’s a cached update in iPhone storage. Delete it, reboot, then try again.

See the section:

As long as Genshin Impact works flawlessly on the current version of iOS, I see no reason to downgrade. :cool:
