What do you mean by strange firmware? Please back up your current firmware and e-mail it to us and to dhc014 (see codeguys.rpc1.org and dhc014.rpc1.org for our e-mail addresses). You can use LtnFW to back up your firmware.
As for getting a .BIN firmware, you can extract the SS0E .BIN firmware (48246S) or the 6S0F .BIN firmware (52246S) from the official firmware flashers using the XFlash Utility. Or, you can download a .BIN firmware of 6S0F from dhc014's website (he doesn't have a copy of SS0E hosted, so you'll have to use XFlash Utility if you want that).
