How can I downgrade from iOS 26 to iOS 18.5?

There is no downgrade.

Resetting to revert to iOS 18.6.2 means no local data is preserved.

Resetting and restoring means some local data — that which has changed since the beta was installed — is lost.

If there are no backups created immediately prior to the installation of the beta, all local data is lost.

iCloud data is probably still available, and apps can be re-downloaded, independent of the reset.

But I’d likely stay with the iOS 26 beta through its upcoming release, as that probably avoids data loss.

Apple is having an announcement on September 9th.

There is no downgrade.

This is an older thread that started during the beta, when iOS 18 was the current shipping version.

It was possible to revert to the shipping iOS version then.

iOS 26 is the current iOS version now, and Apple does not support iOS downgrades.

If you have a backup before the iOS 26, if you tried for beta, You should have a backup copy of a iCloud or iTunes when your device is running 18.5. But Be aware that restoring earlier versions of iOS will reset and erase your iPhone. Theres no other way to revert.

A backup copy of iCloud or iTunes only contains data, not iOS. So restoring an iOS 18 backup will still restore the iPhone to iOS 26. You could only revert from a beta to iOS 18 before the iOS 26 GA release.

You might want to downgrade or even need to downgrade.....but it is not possible to downgrade. That won't change.

Maybe if you could tell us what the issue(s) might be, we might be able to help.

Sorry, you cannot downgrade. Maybe explain exactly what the issue is and we can try to help.

iOS 13 hasn't been signed for several years. Still, you CANNOT downgrade at all.

You have made a mess for yourself and you cannot restore your phone back to 18.5 without a computer. Since you don't have a computer, you clearly aren't a developer, nor did you read or do the things you were told to do when you updated to iOS 26. You most assuredly didn't create an ARCHIVE backup on your computer, so when you do get access to a computer to restore your phone, you're going to LOSE the data on your phone.

Then you should NOT have installed Beta software on your iPhone. Not only do you need a computer, but without one, it means you didn't create an Archive Backup before you unfortunately installed the Beta. You MUST use a computer and without a backup made before hand, you will lose all your data in the restore process.

You may as well live with your mistake until a stable version of iOS 26 is released in the fall.

If you had bothered to read past the first post, you'd have noticed that on every page of this thread is the answer, which is you CAN'T downgrade. Instead of wasting your time and the time of other users, please read a thread before posting the same question which has been answered beyond multiple times.

I don’t know; perhaps if you ask the same question 100 times or so the answer will be different on the 101st😏

Unfortunately, Apple doesn’t allow downgrading to older iOS versions once they’ve stopped signing them. That means you can’t directly downgrade from iOS 26 to iOS 18.5 unless Apple is still signing iOS 18.5 (which is highly unlikely).

What you can do:

Check signing status – go to ipsw.me

and see if iOS 18.5 is still being signed for your device.

Download IPSW file – if it’s signed, download the iOS 18.5 IPSW file for your device.

Restore via Finder/iTunes – connect your iPhone to your computer, open Finder (Mac) or iTunes (Windows), hold Shift (Windows) or Option (Mac) and click “Restore iPhone,” then select the downloaded IPSW file.

If it’s unsigned – you won’t be able to downgrade through official means. The only alternatives are advanced methods like jailbreaks or SHSH blob saving, but those are complex and limited.

So in short: unless Apple is signing iOS 18.5 for your device, downgrading isn’t possible.

I can convert ios 26 to ios 18.6

If you are currently enrolled in the beta programme and wish to return to using the current production version, this support page provides the necessary information to remove the beta from your iPhone:

How to uninstall iOS beta software - Apple Support

Be aware that restoring an earlier version of iOS will completely reset and erase your iPhone. Assuming that you have a pre-existing iCloud or iTunes backup of your iPhone that has not been updated since installing the iOS 26 beta, your locally stored data and files can be restored after returning your iPhone to iOS 18.6.x; if you don't have a pre-existing backup, all locally stored data will be irretrievably lost:

Restore your iPhone, iPad, or iPod touch from a backup - Apple Support

An iCloud or iTunes backup can only be restored to a device running the same or later version of iOS than created (or last updated) the backup. As such a backup created or updated by iOS 26 cannot be restored to a device running iOS 18.x.

Then you "need" something that you can't have. Is there an Apple Store nearby that might be able to help you reset your iPhone?

I'm guessing that if you are unaware of the need to use a computer to downgrade from the iOS 26 beta back to iOS 18, that you also didn't bother to make an archived backup of your data before you installed the beta. That means that you are going to lose all of your data, with the possible exception of data synchronized to iCloud.

Re: “Would like to go back to iOS 18 do you think you could fix it please”

If you installed the production version of iOS 26, you cannot go back, and in any case, you are talking to fellow users who have no ability even to upgrade the version of iOS on your phone.

Correct, restoring the phone does not revert it to an older version of the operating system.

Downgrading the operating system is not possible.
