I have an LG Optimus T, and I downloaded z4root 1.3.1; I selected the Temporary Root, it went through the process, and then z4root closed and brought me back to my home screen. I looked in my App browser and there is no Superuser app. I also tried to use an app that needs rooting and it tells me that my phone isn't rooted. What's the problem here? What do I need to do? As it's a temporary root, I can't turn my phone off or the rooting will go away (right?).... am I doing something wrong? Oh - and another detail - when I try to click on the z4 app, it "transparentizes" to show that it recognizes that it's been pressed, but then doesn't open. I pressed it a couple times and then I got this black screen, which I "home"d out of, and that's that. That's the most I get when I try to open it again. I've been trying this over and over again, rebooting and uninstalling and reinstalling and shutting down and rebooting and I keep getting here. Stuck at a non-root even after I can finally get z4 to "work". -- Would I need to permanently root it in order to reboot it and see if it can finish the root and download superuser? I'm afraid that if I permanently root it I won't be able to unroot it because of the problems I'm having with opening z4 after I've "rooted".
