I want to install Cyanogen Mod 10.1 on my Galaxy S4 with Verizon. I have already successfully rooted the phone. I attempted to use both Goomanager and Recovery Tools to install TWRP and Clockwork recoveries. Each app told me the recovery was successfully installed, however I got error messages both times. With TWRP I got the big android guy on the screen that said DOWNLOADING. With Clockwork, I got a message saying to take the phone into a verizon store. I was successfully able to reboot the phone each time by going into download mode and canceling. According to a 3rd app I downloaded, ROM manager, it recognizes that both custom recoveries are currently installed. How do I boot into one of them?
