No

Return in ios 18

No.

Your wish cannot be granted.

Sorry, but you can’t go back.

You can't. How many times do we need to say it?

Apple is no longer signing iOS 18, so it is unfortunately not possible to downgrade.

no computer to downgrade is there another way to do the change on the iPhone 16 Pro Max to Change to iOS 18.5 without having to have a computer. All I have is my iPhone.

Nope, sorry. Ask a friend or neighbor if you can borrow theirs, if not, visit your nearest Apple Store or Apple Authorized Service Provider to borrow theirs.

Right now, you need to read the more than 17 answers that have already been posted in this thread. We don't need to post the same answer again.

But, before you think about reverting, hopefully you made an Archive Backup of your phone running iOS 18 on your Mac......before.....you installed the beta software.

You will need that Archive Backup to restore the phone using iOS 18 if you want to avoid losing all of the data on your phone and starting all over.

If you backed your phone up to iTunes prior to the update to the beta you can format and restore that backup.

( Instructions do state prior to installing beta to make sure you back up to iTunes.) ❤️

I downloaded iOS 26 and I want iOS 18.5 but I don't have a laptop

Returning an iPhone to the production version of iOS from a beta requires use of a computer - either a Mac or Windows PC. There are no alternatives.

The process is described repeatedly, by multiple contributors, throughout this thread.

Apple told you to use a "spare" phone for the iOS 26 beta. It appears that you did not do this.

Did you make a special "Archive Backup" on your Mac.....before....you installed iOS 26?

If not, you are going to lose all of the data on your phone if you move back to iOS 18.

Please I need too update my IOS

Whether or not you are able to update your iPad to a newer version of iOS/iPadOS will be dictated by the iPad model - and the currently installed version of iOS. You can find this information here:

Settings > General > About

Not sure which iPad you have? Identify your iPad model.

As of 29 July 2025, here is a list of the highest version of iOS supported by the older models of iPad (for simplicity - “generations” are shortened to a number) that are restricted in their ability to be updated:

32-bit devices (obsolete)

iPad1 - iOS 5.1.1

iPad2, iPad3 and iPad mini1 - iOS 9.3.5 (WiFi Only models), iOS 9.3.6 (WiFi+Cellular)

iPad4 - iOS 10.3.3 (WiFi Only), iOS 10.3.4 (WiFi+Cellular)

64-bit devices

iPad Air1*, iPad mini2 and iPad mini3* - iOS 12.5.7

iPad Air2, iPad mini4 - iPadOS 15.8.4

iPad5, iPad Pro (9.7"/12.9" 1st generation)* - iPadOS 16.7.11

iPad6, iPad Pro (10.5"/12.9" 2nd generation) - iPadOS 17.7.9

(*) obsolete

Newer models are all able to be updated to the current version - iPadOS 18.6

• iPad Pro 13" (M4)
• iPad Pro 12.9" (3rd generation and later)
• iPad Pro 11" (1st generation and later + M4)
• iPad Air (3rd generation and later + M2/M3)
• iPad (7th generation and later)
• iPad mini (5th generation and later + A17 Pro)

If your iPad is capable of update to a more recent version of iOS/iPadOS than is currently installed, these support pages outline both the available methods by which the update can be performed - and troubleshooting should you experience difficulties:

Update your iPhone, iPad or iPod touch – Apple Support

If you can't update or restore your iPhone, iPad or iPod touch – Apple Support

If your iPhone, iPad or iPod touch won’t update - Apple Support

iOS update and restore errors – Apple Support

Be aware that while an iPad may be capable of update, in some circumstances you may need to use a computer to perform the update*. To do so, you will need access to either a Windows PC (with iTunes for Windows installed - or the more recent Apple Devices App) or a Mac (with iTunes or Finder - as appropriate for the installed version of MacOS). Ensure that your installed version of iTunes has been updated to the most recent version; the essential device drivers are included.

Download and use iTunes for Windows – Apple Support

Update to the latest version of iTunes – Apple Support

Update software on iPhone, iPad or iPod touch in iTunes on PC - Apple Support

Update your iPhone, iPad, or iPod touch with the Finder - Apple Support

Apple Devices App (Windows PC):

(*) If you don’t have access to a suitable computer of your own, that of a helpful friend or family member will suffice. Alternatively, the technicians at the Genius Bar of your local Apple Store or Apple Authorised Service Provider (AASP) will be delighted to assist.

If you have a beta profile installed, ensure this has been removed from your iPad - as, otherwise, installation of production software updates may be inhibited. This support page provides the necessary information to remove the beta from your iPad:

How to uninstall iOS beta software - Apple Support

You should note that for your iPad to install an available update, its battery must be charged to at least 50% capacity - and/or be connected to its Power Adapter. Similarly, the iPad can only be updated over a standard WiFi connection - or be updated by a PC or Mac using iTunes or Finder - over a USB connection.

If you’re looking to revert from iOS 26 to iOS 18, there are numerous replies in the ten pages of the thread here.

Here is: How to uninstall iOS or iPadOS beta software - Apple Support

You will lose some data by reverting with a backup.

You will lose somewhat more data with a reset, if there is no backup.

If you can’t lose any data, continue with the iOS 26 beta.

I want back ios 18

Apparently you did not ready anything here before posting. You will not get iOS 18 back. The link has also been provided to send feedback to Apple if you wish, they won't know how you feel by posting anything here.

When I try to restore from IOS 26 to IOS 18.5 by putting the iphone in restore mode. IOS 26 keeps coming back on my iphone and not IOS 18.5.

That's correct. Restoring your phone will always result in the installation of the current iOS version available.
