I need help to identify a SMD component
The F1 component is a diode, probably a zener in an SOD962 or SOD882 package. There isn't going to be a good way to find this part without the exact dimensions and the diode voltage.

The red square looks like what is left over from a WLCSP4 or other BGA part, without exact dimensions there is no way to be sure. Without the markings on the part it will be impossible to identify it (Could be one of these)
