that's never happened to me, but it is no to be surprised.
why don't you post your phone's spec so we can help you flash it somehow else?
i had flashed it many times but when i used seus once it gave me new flash menus and i found that cool and i saw there was a new firmware for my phone which i dont have access downloading from TOpSony and i thought i;m gonna use SEUS but it didnt work too bad
