I am having trouble rooting my phone. I first rooted it using the root guide on this website. I downloaded the root checker app, and it says that It is rooted, and I'm able to use apps that require the phone to be rooted, but I believe that It may have been rooted incorrectly because I've been having issues with the recovery. I am trying to flash a custom rom, but I am getting an "signature failed" message. I have installed cwm through rom manager, so that's not the problem. Also, some of the options are missing, such as "backup and restore" "mounts and storage" and "advanced". When I rooted my other phone, those options were there, and from there I could disable signature verification, but it's not showing up on this phone, so I am stuck. Does anyone know why these options aren't appearing, and how to fix this?
