Wtfis

wtfis is an untethered jailbreak for 64-bit devices running iOS/iPadOS 8.0 - 8.4.1. It is a port of the untether exploit from daibutsu, which was only released for 32-bit devices, combined with additional exploits/techniques required for 64-bit devices. Unlike daibutsu, which only supports iOS 8.4.1, it has wider compatibility with all versions of iOS 8.
