Followed steps to a “T” - got phone up and running successfully! However, there is a vertical line in the center of the screen that changes color with whatever button is being displayed in the center screen. For example, a dead battery icon shows a red vertical line, acknowledging a blue “OK” button when setting up the phone shows a blue vertical line, etc. Essentially it’s not a black screen or white lines. Could it be that the display data connector is not correctly attached or perhaps a faulty connector?
