mobile

So yesterday I was trying to flash CM ROM on my Optimus G Pro. I messed up the process and I ended up soft bricking my phone. I was able to flash the stock version of the device to fix the phone. I was attempting to root my phone again and encountered two problems. No matter what I try I can't key press, boot my phone into recovery mode. And when I do it with the adb command it will reboot my phone and just have the android with the exclamation point. I have tried to scour the webs to find how to fix this recovery mode issue but couldn't find anything that worked. Does anyone know what to do?
