This time our article will tell you how to disassemble a Nokia Asha 300 phone, and, besides that, also replace the damaged touch glass. A standard set of dedicated tools will help us achieve our goal. Also, you need to buy a new Nokia Asha 300 touch glass in our VsePlus online store. Armed with everything you need, you can start disassembling.
Before taking the first step in disassembly, turn off the device. We put the phone with the back side up.We open the back cover exactly as shown in the diagram. We remove the battery from the compartment.
Next, take a Phillips screwdriver and unscrew the screws located around the entire perimeter of the phone case.
Then, using a metal spatula, detach the rear panel of the device, pushing it in several places where the panel is fixed. Remove the back panel.
Following this, we take a flat screwdriver and carefully detach the screen that covers the display connector located on the main board. Then immediately snap off the display connector with a metal spatula.
After that, with the same metal spatula, very carefully lift the main board of the phone and remove it from the case.
On the top side of the board are located: system connector, display connector, camera, vibration motor, sim card reader, memory card reader, processor, flash, power controller, radio unit and battery connector.
On the back of the board are: a sensor sensor, touch pad contacts, a keyboard membrane and four LEDs.
We continue to disassemble the Nokia Asha 300 phone further. We take out the keyboard panel from the upper part of the phone case. Then we remove the display very carefully by hand.
All we have in our hands is the top panel of the phone with the touch glass. We need to remove it from this panel. To do this, take a Phillips screwdriver and unscrew the four screws that fix the frame of the touch glass to the panel.
Phone disassembly is complete. Now you can install the new Nokia Asha 300 touch glass. Carefully attach it to the front bezel by screwing the frame with four screws.
And then we install other parts that follow in the correct order during the assembly process.
Nokia Asha 300 teardown is very simple, and replacing the touchscreen or display is also easy. I want to warn you right away that you are doing at your own peril and risk, if something breaks, I am not to blame :)
Disassembly of any device starts from the back cover. It must be removed, then remove the battery, SIM card and memory card, if any. Then we unscrew the six bolts around the perimeter.
