Expand on display cable fix
https://developer.puri.sm/Librem5/Development_Environment/Boards/Troubleshooting/LCD_Problems.html?highlight=cable#procedure already helps a lot but a recent case showed:
a real picture of the misplaced and seated cable
a real picture showing where the connector is placed
instructions how to reseat the cable (basically you filp up the lever (e.g. using a tweezer) tilt the display and flip down the lever again.) This could also include a picture with the lever opened.
would help people to fix this on their own.
