[solved] Your LF / HF Antenna is unusable
Hey guys,
I haven't used my proxmark3 for quite a while like 3-4 months. I decided to use it today, and when I re-setup my computer for (installed driver, etc.) and typed "HW Tune", I got the following error:

The device was well kept in the box... so I am not too sure how the antenna could have got damaged?
The last version I was using was "20161115-unofficial".
Does that mean that I need to change the antenna or buy a new one or it is a normal behaviour that can happen with the hardware?
Thanks!

Re: [solved] Your LF / HF Antenna is unusable
standard recommendations;
check your antenna wires and connectors.
upgrade firmware with latest source from github

Good to hear, may I suggest that you edit your first post and add the prefix [solved] to the subject
