Use the correct screwdriver (usually a Phillips head) to remove these screws. Keep track of where each screw goes! A small container or a magnetic mat can be incredibly helpful here. You don’t want to mix them up.

• Step 2: Locate and Disconnect Flex Cables. These are the delicate ribbons connecting different parts of the phone. Look for small, rectangular connectors that plug into the motherboard and other components. Use a plastic opening tool or your fingernail to gently pry up the connector’s locking mechanism (usually a small flap). Then, carefully slide the flex cable out. Avoid pulling directly on the cable itself; always disconnect from the connector.

• Step 3: Remove Protective Shields. Some components, like the battery or the motherboard, are often covered by metal or plastic shields. These are usually secured with screws or clips. Remove the screws and carefully detach the shields.
• Step 4: Detach the Battery (If Necessary). If you need to replace the battery, you’ll need to detach it. Batteries are often glued in place. Again, apply gentle heat to soften the adhesive. Use a plastic opening tool to carefully pry the battery away from the frame. Be extremely careful not to puncture or bend the battery.

• Step 5: Access the Motherboard and Screen. Once the shields, cables, and battery are removed (or detached), you should have access to the motherboard and screen. These components are usually connected by flex cables as well. Proceed with the same care as before when disconnecting the flex cables.

Safely Detaching Flex Cables and Connectors

Flex cables are the lifelines of your phone, and damaging them is a recipe for disaster. Here’s how to treat them with the respect they deserve.

• Understanding Connector Types: Most connectors have a locking mechanism. This could be a small flap that flips up, a sliding lock, or a simple friction fit. Observe the connector carefully to understand how it locks and unlocks.
• Using the Right Tools: Always use a plastic opening tool or a spudger to detach flex cables. Avoid using metal tools, as they can short-circuit components.
• Gentle Application: Never force anything. If a connector doesn’t budge, double-check that you’ve unlocked it correctly. Apply gentle pressure, and it should release easily.
• Angle of Approach: When detaching a flex cable, approach it at a slight angle. This helps to avoid bending or damaging the connector pins.
• Visual Description:
  

  Imagine a flex cable connector as a small, rectangular box (typically black or white). On one side, you’ll see a series of tiny, gold-colored pins. The flex cable itself is a thin, flat ribbon, often a light tan or grey color. It slides into the connector. A small, usually blue or black, plastic flap (the locking mechanism) is located on top of the connector. When you lift this flap, the cable can be removed. The angle to apply the pressure is around 30 degrees, using a plastic opening tool.

• Protecting the Cables: Once detached, gently fold the flex cables back to prevent them from getting in the way or accidentally being snagged.
