Make sure u have the essential tools need(Bought this toolkit for 10 dollars at walmart)

Take off the micro sd card cover

use the mini pry bar

Shove into the lining between the back and the micro sd card.

When its wedged push it all around the sides

Now that the back is out you are looking at the insides

turn it around then insert the mini pry bar between the screen and the silver border and slide the pry bar around all sides until the silver lining is poping off the screen

unscrew the screws around the battery

Now take out the connectors (all of them)

now take out all the screws that are all around the edges

than you will see that you can just pull the motherboard out
