How to remove ios 8 jailbreak can I factory reset my iPhone?

DO NOT FACTORY RESET!

Most people think it's fine to use the reset function on the phone to remove a jailbreak, this will make your life hell trying to fix as it partly deletes the jailbreak which you then end up in a boot loop.

Saurik (creator of Cydia) has actually created an app called Cydia Impactor which removes the jailbreak without a restore. Just search for it on Cydia

Alternatively you can restore via iTunes (backup first)
