So I use dfu-util (from package dfu-util v 0.7 r 4.fc21) to load the 
firmware image to RAM as you instructed:

[bernard at juglans-nigra HACKRF]$ dfu-util --device 1fc9:000c --alt 0 
--download hackrf-2014.08.1/firmware-bin/hackrf_one_usb_ram.dfu
dfu-util 0.7

Checking hackrf_info before a reset of the board confirms that the 
image was succesfully loaded:

[bernard at juglans-nigra HACKRF]$ hackrf_info
Found HackRF board.
Board ID Number: 2 (HackRF One)
Firmware Version: 2014.08.1
Part ID Number: 0xa000cb3c 0x00584735
Serial Number: 0x00000000 0x00000000 0x457863c8 0x26466d1f

But when I reset the board, I'm back to the old firmware, even if I try 
to write the firmware image to SPI flash with the hackrf_spiflash 
utility before the reset as instructed in the wiki.

Thanks for your help
Bernard.
