To reassemble your device, follow these instructions in reverse order.

Take your e-waste to an R2 or e-Stewards certified recycler.

Bonjour Mathieu, merci de votre attention et de votre remarque. La partie du retrait de la batterie a été ajoutée. Par contre, la carte SIM qui se trouve derrière la carte mère ne dérange pas la procédure. Il n’est donc pas nécessaire de commencer par la retirer. J’espère que vous avez à présent toutes les infos pour effectuer la réparation. Bonne continuation !
