hello nice people of the phandroid forums! I'm new here and will immediatly start with a question. My samsung galaxy s2 is stuck in rebooting. Each time I put the battery in and turn it on it will reboot continuously. I've had some extreme battery problems for a week. The battery life didn't display propperly and the phone would turn off for no reasons. Today it has decided to reboot non-stop apparantly... The only solutions i can come up with is pressing the power button - home butten - volume up. It then asks me to reset to factory settings or update the system from a sd cart. I'd rather not reset to factory settings becouse I'l lose all my data then. So does anyone know how 'update from sd cart' works?
