Hi there, Could You Maybe give Me some advice? My N9 has switched off because of low battery power and when I tried to switch it on again after leaving it on charge for a while it just brings up the Nokia Logo with a wrench icon beneath it, then a yellow warning triangle with a message about software and it switches off again. I have tried to flash it in windows and linux but does not work because it is not detected by the USB? I would appreciate any help to get this phone back to Life.
