Default [Q] Odin modem Flash with Knox warranty Void

Hi All,

Probably a topic which has been covered and answered but I couldn't find an answer for. I have an S4 i9507 and was careless and flashed the device triggering the Knox Warranty Void. I'm not too fussed about the warranty on the device but what would like to do is flash the modem via Odin. I'm not having much luck doing so and returns a FAIL (Auth) error when I try to flash. My question is: Are you still able to flash the modem with Knox Warranty void Flag set to 0*1? Or am I stuck on the baseband I have forever?

Thanks in advance.
