First, do not crosspost.
Second, you don't need a binary firmware! Unless you are forced to use MtkFlash (either to recover a dead drive or because you don't have Windows), there is absolutely no reason to use a raw binary firmware. And in the event that you do need a raw binary firmware, they're fairly easy to obtain, as they are located at the same site where you would go to get the necessary conversion tools.
Please read the FAQs and guides before proceeding so that you know what to do.
