Last week, Apple released the iOS 13.5.1 update to fix the zero-day security vulnerability in iOS 13.5 that allowed a jailbreak. The company is likely to stop signing iOS 13.5 later this week or early next week, so if you’ve accidentally upgraded your iPhone to iOS 13.5.1, follow this guide to change it back to iOS 13.5..
iOS 13.5 is likely to be the last iOS version to be jailbroken. Apple is expected to announce iOS 14 later this month, and after that, developers will likely focus on this. Therefore, if you want to take advantage of a jailbroken iPhone in the coming months, it is recommended to download the version of your device on iOS 13.5. There was also a bug in Unc0ver that automatically updated devices to iOS 13.5.1 even if the automatic update setting was disabled. Fortunately, Apple is still signing iOS 13.5, so you can downgrade your iPhone again by following the guide below.
Downgrade iOS 13.5.1 to iOS 13.5
- You can downgrade your iPhone or iPad to iOS 13.5 as long as Apple continues to sign.
- You will not be able to restore the iOS 13.5.1 backup to your iPhone after downgrading it to iOS 13.5. The backup version and the iOS version must be identical.
- Make a backup of all the data on your iPhone before continuing the degradation process below.

The riskier of the two, but you can downgrade your iPhone to iOS 13.5 with this process without cleaning your device. This makes it significantly faster than the second method of erasing all data from your device.
How to downgrade iOS 13.5.1 to iOS 13.5 without losing data
Deactivate Find my iPhone via the Settings application (Settings> iCloud> Find my iPhone).
Download the iOS 13.5 firmware file for your device from our iOS firmware file download page for your iPhone.
Note: If you download the firmware file with Safari, make sure that the automatic decompression function is disabled or use Chrome or Firefox. Alternatively, renaming the .zip file to a .ipsw file should also work.
- Connect the iOS device with iOS 13.5.1 to your computer.
- Start iTunes and select the iOS device in the upper left corner.
- Then click Summary in the left sidebar.
- Hold Alt / Option on Mac or Shift on Windows on your keyboard and click on the Check for Updates option, rather than restore.
- In the pop-up window, select the iOS 13.5 IPSW firmware file that you previously downloaded.
- iTunes will inform you that it will update the device to iOS 13.5 and will check the update with Apple.
- Click on Update.
- iTunes should now downgrade your iOS device to iOS 13.5.
- If you’re using macOS Catalina, the steps to downgrade your device to iOS 13.5 remain pretty much the same. However, since iTunes is no longer part of the operating system, you will need to open a new Finder window and access your device from there.

iPad and iPad Pro models, iPhone 6s, and older iPhone models:
- Press and hold the power/side button and home buttons at the same time, keep pressing both buttons until you see the recovery-mode screen.
Release the power button and continue pressing the start button until you receive an iTunes pop-up window that has detected that your device is in recovery mode.

- Hold Alt / Option on Mac or Shift on Windows on your keyboard and click the Restore iPhone … (iPad / iPod touch …) button.

- Then click the Restore and Update button to continue.
- On the next screen, it will give you information about iOS 13.5 update. Click the Next button, then click the Accept button to continue.

Once the process is complete, your iPhone will restart in iOS 13.5 and you should see the white “Hello” configuration screen. Follow the installation process now, and if you have an archived backup of iOS 13.5, restore during the installation process.
