Default [Q] Which jtag/usb jig does work on a Nexus 5

I bought my Nexus 5 just a couple of weeks ago and yesterday it bricked all of a sudden. The phone isn't rooted and/or modded.
I'm going to send it back and receive a new one but I'd really like to see if I can unbrick it on my own (assuming the problem isn't hardware).

Is there a jtag/usb jig that works for the Nexus 5?

Thank you
