Do you have suggestions on how to apply heat to this small parameter around the screen? You mentioned 40C which is 104F but all heat guns I've seen start at 750F and up.....if I used a hair drier, I fear it may damage the screen as it would be too wide of an area of heat being applied.....also I see the 64GB ATP sd card will work ok, but I need to be sure that I can access the card over USB, I understand it will be slow, but if tracking down an extender cable is really difficult then I can deal with the long wait times. Am I correct is saying that the issue of the sd card corruption only happens when accessing the card over USB while using the extender? Or does this happen as well plugged directly into the board?
