I'm new to rooting and such I have a Samsung captivate, and its rooted i did all the research i possibly could. I did it successfully, but now it been rooted for a few months now, and suddenly when the phone goes into lock i try to unlock it by sliding the picture it doesn't work, if I don't let the screen lock, it works wonderfully. If I hold the unlock button to where the power, airplane mode etc if i tap the power off button a on the screen a few times it works but i can't figure it out, and i thought maybe a fresh install of a ROM but i keep getting "E:signature verification failed, installation aborted" If anyone can help this is the only phone i have use it everyday please and thanks
thanks
