I am running the Z4root and it has said "running exploit in order to obtain root access" for a while. I rebooted twice, but it just keeps saying that. How long should it do this for? And what should I do?
Try pulling the battery out for a minute and put it back in and try again...did you download the correct z4 root app for your phone too? Another idea might be to delete the z4 root app off your memory card and redownload it again.
