Use WinRAR to extract the files.
There are 1.img, 2.img, 3.img, etc etc archives. Focus on the 1.img
Now, like when you flash the recovery on the command line (fastboot flash recovery recovery.img), you will flash this one this way:
fastboot flash modem 1.img
Remember to put the 1.img archive on the same folder that you have the fastboot archive.
And that's it. Reboot, and then flash RSD with Stock. Then with you favorite custom ROM.
Hope it works for you. Please let me know if you need further assistance.
