In the final step, I would not say that you should "tear" the screen out ("gently remove" would probably be better)
In Step 7, mention that you should use the plastic tools to pop the speakers out of the device.
In this guide, you missed a step on removing the battery.
Also, mention that you can disconnect the battery from the device by gently pulling out the battery and gently lifting up the wires.
In Step 3, mention that you need to lift up on the black locks to take out the ribbons.
