Read the steps before, do NOT memorize them!
Be prepared. RIGHT tools, parts, proper workspace, no disturbance for the next hour.
Patience!
Be "OCD" cautious and systematic!
Study carefully the positions of every little tabs, holes, screws, cables... Take notes, mark your screws, etc...
Proceed like a neuro-surgeon. Very gently, but firmly, precisely. And do not improvise! Follow the steps as described!
Be extra carefull on your way back to rebuild:
*At step 7, there is a small black metallic tab that should go UNDER the metallic screw hole tab. Invisible before you remove the metallic plate holding the LCD.
Consider that before screwing back anything from step 10 onward to step 1.
Inserting the FPC connector at step 6 is easier when you aim externally, from where you can see the top edge and the glass plate, holding the casing and the glass plate at a 90deg angle from one another. Between these two parts, with a proper lighting, it is easier to see where to insert the connector.
Tweezers are helpful here.
