So I start with sbsetting then, winterboard, dreamboard, springtomize, full force, retina pad. I always reboot my iPad after every app. It's around this time that when I reboot it locks me to the back screen with the apple logo. Then I have restore factory settings with iTunes and restart the jailbreaking process over again. I have tried about 5 times now. There is not an exact app that I download that causes the crash because sometimes I get barrel,black keyboard, no spot and I file installed.
