I followed your insteuctions but it did not work. When I remove the battery and it’s on charge, there is continuously the “fairphone” opening page then a vibration,then all black, then opening page again etc and it does not stop. When I put the battery back inside the phone I cannot turn it on… It stays all black. I think the shock must have disturbed some circuits or something. It’s really weird as if the phone could not connect with the battery. The battery is only 3 months old and was working perfectly well until last night.
