as others my FP2 is a victim of the colored pixels failure. Tried swapping the screen with a friend, there is no doubt and the core module is responsible for it. I contacted support, but they agreed with me that a 300€ repair is not worth it, and even though they are probably receiving FP2s for FP3 discounts, it seems that reselling second hand spare pieces is not (hopefully yet ?) part of their recycling plan. I contacted the nearest Faiphone angel in Grenoble, but no spares there to purchase, thanks for a quick reply anyway. There is the oven solution, but I’m not very confident is baking circuit boards in the same kitchen oven that I use for cooking, especially with a kid.
So there I am looking for a FP2 core module. I beleive I can at least offer 50€ plus shipping to Lyon (France) to be competitive with the Fairphone recycling program !
