Hi i have Iphone 6 ios 8.1.2 jailbraked with Taig. Last morning i was using safari and then suddenly it got stuck. After 2-3 seconds blue screen flashed and phone restarted. After restart barrel was not working, wifi cant be set to on from settings and apps wont start even Cydia (open then suddenly exit). What can i do thanks ? i have tried starting in safe mode but no luck.
