A mi me paso lo mismo con mi SEw300i, y no lo detectaba ningun problema de flasheo, hasta que me di cuenta de algo, el computador que habitualmente usas para los flasheos, ya no te va a servir por que este se "acostumbro" a reconocer el dispositivo "Sony Ericsson Flash Device" y cuando tiene el problema de la pantalla blanca se "transforma" en "Generic Flash Device" pero como ya instalo un dispositivo flash, ya no va a instalar en nuevo (eso no se porque)
Me consegui un nuevo PC e instale nuevamente el ggsetup, luego conectas el cel en modo flash y va a reconocer el "Generic Flash Device" (Si dice "Dispositivo Desconocido", es la batería), luego le das a la segunda opcion, siguiente, y luego en "No buscar, seleccionare el controlador", luego aparecera una pantalla con el nombre del Dispositivo de Flash Generico y lo seleccionas y le das siguiente, y voila, tu SE esta instalado.
Retiras el cel, inicias tu programa de flasheo, recomiendo XS++ ya que SeTool comienza con el error NAK, o el ldk o Unknown ChipID, RETRY.
Y haces full flash, no el flash de main, flasheas TODO!
Por lo menos me funciono a mi xD
PD: este es el log de mi flasheo, espero que te sirva.
