But I can another Write Flsah File...
You can not downgrade the bootloader components and you might not be able to write certain segments of the firmware that have been signed with a security key that is now blacklisted in the new bootloader.
Since you already have knox 0x1 you might want to look into installing (from a custom recovery) a custom ROM based on the version that you want - for instance a version that is deodexed and rooted might work. But pay attention to the other similar threads around, eventually ask in the exact thread where you find the ROM.
