Unable to unbrick Proxmark 3 RDV - looking for professional help

Hi Guys, after several tries with JTAG, I have to admit I’m not able to unbrick my Proxmark. Is there anyone in Portugal or Spain that could this for me for a fee ? also upgrade it to the latest version because thats were it bricked the first time.

Have you followed this excellent guide by @donfire?

I did, several times, so i’m humbling quitting doing it on my own.
