Huawei P7 – Disassembling procedure – How to replace the screen

Heat the glass panel on the back to around 85 Degree C so the adhesive loosens.
Use a plastic spudger or opening tool to gently pry up the glass.
Carefully work your way around the edges.
Be careful at the bottom. There is a flex cable running near the back-glass.
Never use metal tools for this. Metal will scratch the black paint off the back plate.

First, disconnect the battery cable.
Use a philips screwdriver to remove the shield, revealing the battery connection.
Next, disconnect the LCD/Digitizer ribbon.
Remove the battery.
Use plastic tools to pry the battery off its adhesive.
Don't bend, or heat the battery.
Heat the front side to about 85 Degree C.
Using a plastic tool, separate the display from the frame, but don't pull it too far away.
Flipping the phone over, can see the display ribbon.
Make sure none of this cable is stuck to the frame.
Pull the display ribbon through the frame.
If the screen broken while removing,make sure there is not a single glass-shard left on the frame. Any little splinter will cause significant damage to the new screen you're about to place.
Tape up the whole frame with double-sided tape for a perfect fit that won't become loose.
