Apple has released the iOS 8.4.1 update last week and that brought the end to the TaiG iOS 8.4 jailbreak. With other words, if you will update your device to iOS 8.4.1, you will not be able to jailbreak the iOS device anymore (at least… not for now).
However, keep in mind that Apple is still signing the iOS 8.4 firmware and you will still be able to downgrade to the previous iOS version and by doing this, you will be able to “re-jailbreak” your iPhone, iPad or iPod Touch device.
It is not that hard to downgrade the iOS firmware to the previous version and it doesn’t require too much time. However, before thinking about downgrading the iOS from an iPhone, iPad or iPod Touch, we suggest you to backup all the data in order to make sure that you will not lose anything in case something goes wrong.
Keep in mind that the iTunes backup from the iOS 8.4.1 will not work in iOS 8.4, which means that you will need to perform a manual backup.
Downgrading your iPhone, iPad or iPod Touch from iOS 8.4.1 to iOS 8.4
First of all, you will need to download the iOS 8.4 IPSW to your iPhone, iPad or iPod Touch. After that, you will have to disable the “TouchID/Passcode” and “Find my iPhone” features.
Then connect your iPhone, iPad or iPod Touch to your Windows PC/Mac and wait for the iTunes application to launch. Select your device (iPhone, iPad, iPod Touch) and click on the “Restore” button while holding the Shift button while on Windows PC or Option while on Mac.
Now, you will need to go to the folder where you’ve saved the iOS 8.4 IPSW and the downgrade process will start. When your device will be successfully downgraded to iOS 8.4, it will automatically reboot. Once it boots back, you will see that your iPhone, iPad or iPod Touch is running on iOS 8.4, which means that you can “re-jailbreak” your device using the TaiG tool for Windows or Mac.
