Which page of the wikia re you looking at?  Is it the getting started
page?  What about it do you think is out of date?  I'd be happy to
update it.

Using the gnuradio pybombs script is fairly reliable for most people.

Thanks,

It sounds like the RX amplifier may have been damaged by that signal.

Could you try running your hackrf_transfer -r command again with the
RX amp explicitly disabled?  Then with it explicitly enabled?  Do you
see any difference in the output?

Thanks,
  Dominic

That looks like a fairly reasonable set of instructions for the time,
but I would recommend that anyone not planning to modify libhackrf or
the hackrf firmware should use the last stable release (2014.08).  As
previously mentioned, pybombs would be my preferred method for
installing all of the hackrf and gnuradio tools that you will likely
want to use.

If for any reason you aren't able to use pybombs, then I you can
follow that guide but download the release instead of cloning the git
repository.

Thanks,
  Dominic

Frank,  I am no Hackrf expert, but I fear you fried the first stage of 
the receiver.  The Wiki warning reads

"Receive Power

The maximum RX power of HackRF One is -5 dBm. Exceeding -5 dBm can 
result in permanent damage!

In theory, HackRF One can safely accept up to 10 dBm with the front-end 
RX amplifier disabled. However, a simple software or user error could 
enable the amplifier, resulting in permanent damage. It is better to use 
an external attenuator than to risk damage."

Assuming you had an antenna connected when the 0.5 watt transmission was 
made, the power was probably just too much for the first stage.  I would 
troubleshoot that portion of the radio."

The possible good news is that this probably happened to a lot of people 
so you should be able to get advice which components likely need replacing.

Good luck, Fred
