Have your jailbroken your iPhone X, 8 Plus, 7 Plus, 6S, SE or iPad Air/Mini on iOS 11 – 11.1.2 using Houdini11 or LiberiOS and now want to restore without updating to latest version? If answer is yes, then Prometheus is the tool that can rescue you out of this miserable situation.
Restoring your iPhone or iPad to factory setting is simple task. It can be easily done with iTunes. However, it becomes difficult if you try to jailbreak your iDevice. The reason is that after jailbreaking the device, it is very difficult for iTunes to recognize it.
Most people end up updating to latest iOS version available in that cases. However, the problem is addressed by jailbreak developers now and also solved.
Thanks to a new utility called Prometheus. It can help you restore your iPhone/iPad to iOS 11, 11.1.2 and iOS 11.2.1 factory setting without updating it, thus help you stay on previous version. This way, you can be prepared for future jailbreak release.
It is to mention that Prometheus is not easy to use. Rather it require some basic knowledge of jailbreak and Cydia as pre-requisite. So if you feel you have that much knowledge then please proceed at your own risk.
