Wäre super, wenn ein extriges Bild zur Demontage des Mainboards gemacht wird in welchem Winkel das Werkzeug angesetzt gehört.

An sonsten gute Anleitung.

So much parts you needn't to remove in this tutorial for a screen replacement ! Only move the sensor and screen flex by removing the three screws and metal parts at the back of the motherboard and the seven screws on the sub board with the black plastic part and its over ! Don't overmanipulate and dissambly your gear for nothing, you'll lose money and time.

Hi buddy. I believe you a referring to a situation where only the front panel is being replaced. In the tutorial the entire front assembly was being replaced. This includes the LCD and frame. The entire device had to be transferred. No shortcuts there.

If get you clear, you mean the screen alone can not be replaced? Meaning you have to replace the frame as well?
