this happened on my iphone 5 but im posting here to see if anyone has had this issue with their ipad. i opened cydia, saw i had to updates, one was bytafont big boss and the other was winterboard. i updated both at the same time. seemed to load fine, clicked respring. after trying to respring it got stuck on dim apple logo. tried hard reset, looked like it was going to work but went back to dim apple logo, tried holding the volume up button, again looked like it was going to work but again stuck on dim apple logo. im thinking i have no other choice but to unjailbreak?
