Be careful around the antenna when removing the display. I sheared the antenna sticker in half and needed to wait 30 days for a new antenna (25$).

Otherwise, the repair was very doable once the screen is off. The recommended adhesive (tesa), does make the display sit lower than original, giving the border a slight sharp edge all around. I would recommend a slightly thicker adhesive for reassembly.

You need to heat it a lot. I used heat gun at 280°C and applied heat to the edges and kept it moving around the edges for 15 min. Then the edge was too hot to touch (around 120-150°C) and then it was easy to remove the screen. Be careful for the top antenna’s mine were stuck to the display instead of the bar below and I needed a new antenna.

Would a nvmeSamsung 970 Pro 512GB work as a replacement on a device as old as the Surface PRO 4? Or would it be better to go for a 850 pro (around the same time period as when the Surface was launched)?
