Wait... are you actually typing recovery.img? If so, I would double check to make sure your recovery image is actually named recovery.img because that's the actual image file you want to flash to the recovery.Not getting any error message it just says "cannot load recovery.img"
I have tried with and without the .img and always the same?
Tried going through the whole process again on my laptop incase I had missed something but exactly the same.
When I unlock it I follow the onscreen instructions and at the end it says its complete before it reboots. Then I turn on usb debugging again and reboot bootloader all ok but won't let me load the new recovery?
Normally I would just say it wasn't meant to be and leave as it is but I wont be beaten on this so I'm purposely not installing anything on it till its done. Any ideas apart from bringing it round yours lol ;-)

For an example, if the recovery image is titled Rouge_Recovery_to_Awesomeness.img then you MUST type that into the commend prompt as fastboot flash recovery Rouge_Recovery_to_Awesomeness.img, or rename the file to just recovery and do it again, otherwise you will get that error message.
