Want to downgrade from iOS 26 to 18, but don’t know how? Follow the guide to know how you can do so. We shall also discuss the possible reasons that people prefer to do so. So, let us begin.
Can one downgrade from one iOS to another?
To answer your question fairly, downgrading from one iOS version to another is generally not supported by Apple. The company signs specific iOS versions, and once a new version is released in the market, Apple usually stops “signing” the old one within a short period. This is necessary to maintain the upgraded quality of work in the Apple world. This signing process is a security measure that verifies the integrity of the software and protects the data of the users. Without a valid signature, you cannot install the older version on your device. While it’s possible to downgrade from a beta version to the most recent release, honestly speaking, going back to a previous public version is only possible for a very limited time after a new update drops. Yes! You heard it! If you want to do it, do it quickly. If you miss that small window, you’re essentially locked into the current or newer version of iOS.
Steps to downgrade from iOS 26 to 18
Now that we know what the situation is, with downgrading from one iOS to another, let us discuss the steps for the same.
Most importantly – Backup Your Data
Before you do anything, create a full backup of your device on a computer. This is absolutely necessary; otherwise, there is a high risk that you may lose your data and information stored on the device. An iCloud backup may not be compatible with an older iOS version, so you’ve got to find alternatives. Be aware that a backup made on iOS 26 can’t be restored to a device running iOS 18, so any new data will be lost unless you have an older backup already prepared.
Turn off Find My iPhone
As the next step, you also need to turn off ‘Find My’. To do this, just go to Settings > Your Name > Find My > Find My iPhone and turn it off. You’ll need to enter your Apple ID password to proceed.
Download the Firmware
Go to a trusted site like IPSW.me to download the official firmware file for iOS 18. While doing that, make sure you select the correct file for your specific iPhone model.
Enter the Recovery Mode
Now connect your iPhone to your computer and open Finder or iTunes. You’ll need to put your phone into Recovery Mode. The exact steps vary by iPhone model, so this may bring about slight changes in the exact steps. So, make sure you check that up before you proceed to do anything.
Finally, Restore Your iPhone
Once your device is in Recovery Mode, a pop-up will appear on your computer. Hold the “Option” key on Mac or the “Shift” key on Windows and click the “Restore iPhone” button next. A file browser will open on your screen, allowing you to select the .ipsw file you downloaded. The process will wipe your device and install the older iOS version, which you can now comfortably use.
