Warm the Back Cover. You can use a hairdryer.
Be careful, the Cover is plastic.
Use a small suction cup and plastic tools for separating the Rear panel.
Before installing the new cover, you must clean the phone from the old adhesive tape and install a new one if your spare part has come without double sided adhesive tape.
Disconnect the Battery Cable.
The battery is stuck to the phone fame. Use the white tape to remove it.
Li-Polymer Battery, 2230 mAh Part number: LIS1551ERPC
Remove the SIM and the memory cards.
Remove x4 T5 Torx Corner screws & x2 T5 Torx Screws on the Board
Disconnect one by one: Touchscreen flex cable Proximity sensor flex cable Power on, Volume buttons cable SIM & Micro SD flex cable Coaxial antenna cable
Disconnect the LCD Display flex cable. The connector is on the other side of the board, under the Power/Volume buttons flex cable connector.
Put one plastic spudger between the Logic board and the Main frame.
Step one: move aside less the left side of the board - down.
Step two: the left side of the Logic board must go out of the main frame.
For this manipulation use only plastic tools.
Let's first test the new spare parts.
Use a scotch tape for the broken glass.
Unstuck the LCD Display flex cable from the Main frame.
Now preheat the glass before removing. This will soften the adhesive and will make separating more easy.
You can use a hairdryer.
With a cutter, make a room for a plastic tool, then continue with separating the Touchscreen & LCD Display from the frame.
This is the Display Assembly.
The LCD Display and the Touchscreen are not firmly bonded, while some other other models.
If your Touchscreen or LCD Display is OK, separate them carefully.
In our situation, both of them are broken.
Clean the frame from the remains of tape.
Install the LCD Display and the flex cable on its correct place.
Could not find adhesive sticker for this model, so used universal adhesive tape 3M – 3 mm.
Don't forget to remove protectors from the LCD Display and from the inner side of the Touchscreen.
