How do I tear down a Alcatel one touch fierce a30

My power button has come off and I have tried the reboot tricks with the volume buttons. Didn't work usb cord and laptop didn't work. I found out those trick doesn't work on lollipop and higher. So I am hoping to in other words jump start my power port. But I can not get the pass the middle cover which protects the battery. If anyone knows how to remove it without breaking it please help me.
