If the jailbreak process gets stuck somewhere, close evasi0n, reboot the device by holding the Home and Power buttons at the same time until it restarts, and restart the jailbreak process. evasi0n takes roughly 5 minutes to jailbreak the device. Once the jailbreak process is complete, open Cydia and allow it to refresh its sources. Once it closes, open Cydia again and in the ‘Changes’ section, update ‘evasi0n 6.x Untether’. Once you do that your device will be completely jailbroken and you can continue to install any jailbreak tweaks/apps/themes you choose.
