Bonjour cher ami

Grace a vous je me suis lancé dans le remplacement de mon ecran explosé par le passage d’un véhicule. j’ai suivi vos explications a la lettre dans le démontage et pour le remontage aussi vous n’avez pas signalé de récupérer le revêtement de cuivre, j’ai réussi de le décoller en chauffant. Tout fonctionne comme avant.

Merci de ce tuto. Félicitations.
