i just tried to jailbreak using blackra1n, but when it said "done, wait for reboot" nothing happens, i can see that the screen is on, but it is just black. i havent heard of anyone else with this problem, i wait for 15 minutes and still nothing happens. also, i tried using spirit when blackra1n didnt work, and it seemed to work (when it got to the space screen with the loading bar, but then the bar fully loaded, and it got stuck with one of those spinning icons which never stopped. very frustrating. any help is appreciated.
