- Turn off the device, disconnect the battery and use ESD protection before starting the repair.

- Carefully remove the back cover and the necessary components to access the main interconnection flex cable.

- Locate both ends of the flexible cable and disconnect them using suitable tools to prevent connector damage.

- Remove the damaged flex cable while following its original routing and avoiding pressure on nearby components.

- Inspect the connectors on both boards and check that there is no dirt, corrosion or damage to the contacts.

- Install the new GH82-38880A flex cable following its correct orientation and mounting curvature, avoiding sharp bends.

- Correctly align the connectors and connect them without forcing the flexible cable or contact points.

- Reconnect the battery and check device operation, charging and communication with the components connected to the interface board before final closure.

- Clean adhesive residue, replace the necessary fixing elements and check the back cover fit before completing the repair.
