disconnected sd while updating OS

[marsuper33]

while updating the OS my younger brother got a stupied idea to remove the memory, so he did then the computer told that the device is not connected.
now screen says: Error 507, Reload Software

now while reloading it stops on connect to boot rom, then shows that the mobile is disconnected
I tried connecting while battery removed as per many forums but waited too much and nothing happened
I tried connecting waiting the usb-pin: unknown but never got it too it will directly boot and give the error message.

any help
