Excellent but i find nowhere an explanation of how to reassembly, mainly how to adhere the keyboard glass surface to the base chasis. I mean, is still usable the same original adhesive heated in the first step or a two sides adhesive frame has to be placed after removing the old adhesive (or just aplying a sort of glue -¿wich one?-). I’ not sure I’ve made it clear, I hope yes. Thanks in advance.
