This article will provide a detailed guide on how to downgrade from iOS 18 to iOS 17. Let's take a look.

Step 1. To begin, go to the IPSW Download page and download the firmware that matches your specific iPhone model. Make sure to select only the signed iOS versions, as these have been verified and approved by Apple.

Step 2. Navigate to "Settings" > [Your Name] > "Find My" > "Find My iPhone", and disable this setting. (How to turn off Find My iPhone without password?)

Step 5. Select the iOS 17 IPSW file you downloaded and click "Open". When prompted, confirm that you want to restore to iOS 17.

Here is how to go back to iOS 17 from 18 via Settings:

Step 1. Open "Settings", then go to "General" on your iPhone.

Part 3. FAQs on Downgrading from iOS 18

Q1. Is downgrading from iOS 18 legal?

Downgrading iOS versions is legal as long as Apple is still signing the version. However, Apple does not encourage users to downgrade, as newer versions typically include security updates and feature improvements.

Q2. Can I downgrade iOS if Apple stops signing the version?

Unfortunately, no. Downgrading usually depends on Apple "signing" older iOS versions. This signature acts as a verification key, enabling your device to recognize and install the older software. If Apple stops signing iOS 17, downgrading will become very challenging.

Q3. Will I lose data if I downgrade iOS?

It depends on the method you use for downgrading. If you choose the iTunes method to downgrade from iOS 18 to iOS 17, it will erase all your phone data. Therefore, you should back up your iPhone data before proceeding with iTunes. If you want to downgrade from iOS 18 without losing your data, it is recommended to use iOS System Recovery, which allows you to downgrade with a single click while preserving your data.

Conclusion

That's all about how to downgrade from iOS 18. If you plan to downgrade from iOS 18 to iOS 17, make sure to back up your data before proceeding and choose the method that best suits your needs. It is recommended to use iOS System Recovery, which not only supports safe downgrading but also helps prevent data loss. Regardless of the method you choose, following the correct steps will ensure a smooth return to your previous iOS version.
