I've tried everything, 3 different cables, 3 different PCs, baterry is full, trying removing battery etc. This phone is behaving very strange, when i press power on button to give a sign to program that phone is connected and ready phone lights up for 1 second and turns off. It should lights up not till then after pressing and hold power on button for 1 second, and when i press it for short time nothing should happen but it lights up!!!
I don't have a clue why!
Sorry for my English
Best regards.
