Firmware header not supported; firmware checksums may be incorrect.

[Google Code Exporter]

I used extract-firmware.sh on this file: 
http://www.win-star.com/download/drivers/fireware/11-WN523N2-B1_W8_standard_MRE2
-B1.344..20130809.Nohw_fwc.bin

It extracted everything correctly.

When I use build-firmware.sh without modifying anything I get the following 
error
Firmware header not supported; firmware checksums may be incorrect.

Also I am not able to upgrade the firmware with the new firmware.bin that was 
created.
