Insert the flat end of the spudger tool  in the crack beneath the battery. Move the spudger tool carefully side to side to remove the glue that is holding the battery in place. This is a soft battery, so a little bending is expected.

With the power cable disconnected, the backside camera is free. However, both cameras are sequentially connected through the power cable; the front side camera is glued to the motherboard. Using tweezers, carefully grab the front camera and twist slowly. The camera should release easily, do not twist too hard.

Grab the now loose motherboard and move it to any side of the case. There is still one cable connecting the  motherboard to the screen. Since it does not hurts the process, you can leave it there until the end. If you want to remove it now, go to Step 25 and then come back.

I think that remove the microphone, speakers and cameras are unnecessary. I had change the digiter and don't remove anything just the screws and be careful with the speaker and unlock the digiter cable in the left upper side and that's the parts that I had removed then the parts that you need remove is the battery and the 3 screws and unlock all the cables and the parts attached to the screen and that's it....
