Basically, the exploit lets you reactivate the Pangu jailbreak by just navigating to https://jbme.qwertyoruiop.com/ and clicking Go.
To use this tool, you must already have jailbroken your device by following one of the tutorials below:
● How to Jailbreak Your iPhone on iOS 9.3.3 Using Pangu and Cydia Impactor (Windows)
● How to Jailbreak Your iPhone on iOS 9.3.3 Using Pangu and Cydia Impactor (Mac)
Once jailbroken, you won't have to worry about your certificate expiring, as you will be able to use the new browser based tool to reactivate after reboot.
To make things easier, you may want to add the site to your home screen as a webclip. Once you do so, an Internet connection will no longer be required to re-enable the jailbreak.
