Mototrola Moto G3 won't charge, volume down and power button don't work! Please help?

I tried to root my phone and did everything androidxda told me to do. I then accidentally pressed the power button and my phone turned on. It now doesn't charge, lock and the volume down doesn't work, everything else is fine. I was on step 12 of androidxda How to root Motorola Moto G (2015) when this happened! Can anyone please help me?
