Let Us Take Real Example Scenario

Hello everyone, I’m new here. This is my first time posting so I don’t really know if I’m posting at the right place.

Anyway, I don’t know how to start but I rooted my LG optimus G pro and everything was fine. I wanted to install a custom recovery and I downloaded this apk called G pro recovery. I installed it and everything was okay but as soon as I rebooted my phone, it took time to start but it did come on.

The apk did not work and no recovery was installed but after that my SD card stopped working. It stopped mounting and even though I try to “Mount external SD” it would just show, ‘sd card is inserted’ but nothing else happens.

I tried doing a factory reset but the problem persists. Please help as everything is okay except the sd card and I tried using it on other phones and it works fine and i tried using another sd card but it doesn’t work so the problem is within the phone. Please help as I have a titanium back up of my stuff on my external sd and I can’t restore it if it doesn’t work right? I can’t really type it all so please reply and I can provide further info.
