Ukoliko je tvoj problem samo kamera,nemas potrebe da radis instalaciju novog OS-a.
Samo uradi hard reset i resio si problem-evo i uputstva za tu proceduru:
Hard reset: Press and hold the Left SOFT KEY and Right SOFT KEY, and at the same time, use the stylus to press the RESET button at the bottom of your device. You will be presented with a menu saying 'press R to reset, X to exit', if you press R Your device will be set back to factory default settings.
(The L/R soft keys are the "- -" keys just above the start and OK buttons).
Ovim postupkom vracas sva podesavanja na fabricka i brises sve podatke iz interne memorije uredjaja(ukoliko zelis da neke podatke sacuvas,uradi backup/restore).
Iskren pozdrav.
