I recently rooted my att galaxy s4 using the pwn method through the sd card and terminal emulator. I know it is rooted and have downloaded many root apps but I badly want to get cyanoginemod. Iv'e tried to get Clockwork Recovery or TWRP in different ways but it won't work. When I boot into download mode it just stays there and I end up having to rip the battery out and restart the phone. I have tried Rom manager and Goo Manager; Rom manager thinks I have Clockwork recovery but I can't boot into it, and I can't even download anything on Goo Manager. Am I making some noob mistake...how can I get a recovery flashed? Any help would be great!

Thanks,
