How to Downgrade to iOS 12.4 for Jailbreak

After @pwn20wnd team has dropped Unc0ver jailbreak for iOS 12.4, Apple quickly releases iOS 12.4.1 update to get rid of the jailbreak. In case you have already updated to iOS 12.4.1 version, but you want the jailbreak, you should quickly downgrade your iPhone/iPad to iOS 12.4 version before Apple stops signing it.

Apple is likely to stop signing iOS 12.4 in the next few days, so you should right now consider returning to the lower version on your iPhone/iPad. This is even applicable for A12.x Bionic devices like iPhone XS, XS Max since an iOS 12.4 jailbreak for them seems to be released soon.

How to downgrade to iOS 12.4 on iPhone/iPad for jailbreak

Method 1:

This process might be risker but you can downgrade to lower iOS version without losing data on your iPhone/iPad. It will be faster than the second method, which includes both erasing your device and reinstall the iOS version.

Steps to downgrade iOS 12.4 without losing data

Here is how to downgrade to iOS 12.4 without affecting any data on your iPhone/iPad

Step 1: On your device, go to Settings > tap on Apple ID banner at the top and disable Find My iPhone

Step 2: Download the iOS 12.4 firmware file for your iPhone/iPad from https://ipsw.me/.

Step 3: Unlock your iOS device and connect it to the computer.

Step 5: Click on the Summary tab in the left sidebar.

Step 6: Hold the Option key on Mac or Shift Key in Windows and select Check for Update option.

Step 7: Browse to the folder containing the iOS 12.4 ipsw firmware you downloaded earlier.

This method is much safer, but it will need more time since it will erase your iPhone storage. Make sure you have already created an iOS 12.4 backup of data since you are unable to restore an iOS 12.4.1 backup on your iPhone/iPad after the downgrade.  If you don’t have a previous backup, you cannot restore your iPhone after returning to iOS 12.4 version.
