Apple has just released iOS 12.4.1 for all compatible devices. In your excitement, you may have upgraded your iPhone or iPad to that latest release but it means that you have played into Apple’s hands and lost the ability to jailbreak. We’re going to show you how to exploit the very small window of opportunity to get back to iOS 12.4 and jailbreak your device using unc0ver.
Apple made a catastrophic mistake when it released iOS 12.4 towards the end of July 2019. The company managed to regress its own security patches to push out a build of firmware which had a fundamental vulnerability allowing for a public jailbreak to be put in place.
The recent release of iOS 12.4.1 is Apple’s answer to that regression, which, unfortunately for a lot of people, patches the issue and halts jailbreaking on the latest firmware for the time being. Thankfully, iOS 12.4 is still being singled by Apple, which means that there is a small window of opportunity to actually downgrade and re-jailbreak. Let’s check it out.
Step 1: First and foremost, if you are running iOS 12.4.1 – which is the latest Apple release designed to fix the security blunder that the company made with the release of iOS 12.4 – then you will need to downgrade in the first instance. Apple is still signing iOS 12.4, so it is possible to download. Follow this guide right here to downgrade your device from iOS 12.4.1 to the jailbreakable iOS 12.4.
If you are viewing this on your newly jailbroken iOS device, then you will notice that you have that gorgeous and oh-so-familiar Cydia icon sitting on your Springboard. As long as you have run the jailbreak successfully, then Cydia will launch just like any other applications and give you full access to the world of jailbreaking. But wait, you aren’t finished yet. Now that you are jailbroken, you will want to do the following to make sure you secure your jailbreak:
Step 3: Save SHSH2 blobs for 12.4 for future downgrading. You can do that by heading here: https://tsssaver.1conan.com
Step 4: Head to Settings > General > Software Update > Automatic Updates and toggle “Automatic Updates” OFF. This ensures that the iOS system will never automatically upgrade you beyond iOS 12.4
