With sad heart I offer my dead FP1 for spare parts. My guess is the motherboard is broken as the phone just froze and never came back to life in spite all my efforts. In the time of fail all hardware like camera, sound,… was functioning fully.
The phone is in good state, with all the eye could see functional (ports, camera…). The screen has one small scratch in lower part, cca 8mm long and shallow, but is fully functional.
It is possible to include also a new battery (bought in December 2016, used to months, fully functional).
Concerning the price, please make me an offer.
I am in the Czech Republic and prefer to send within EU and payment with PP.
