Iphone jailbreak stuck on apple logo starting up
So I updated like 7 things with cydia and when it rebooted it got stuck onto the apple logo, So after messing with it for about 2 hours i got it on the safe mode some how, I restarted it and then it got stuck on the apple logo once again, and after another couple of hours I got it on safe mode again… What should i do to be able to use it again on regular. I have access to everything now but I want to use my jail breaks again so what should I do, Thanks also its unteathered and its on ios 5 iphone 4
