To begin with, we must apply heat to the back cover to soften the adhesive that holds it, we can apply heat several times since the adhesive is quite strong. With a fine tool we will open a small hole through which we will introduce one or more plastic spikes, so as not to damage the paint of the casing, and we will take off the entire edge.

Taking advantage of the heat that we have applied to the back cover in the previous step, simply pushing on the lens will detach it from the back cover.
