[solved] PM3 bricked?

Hi,

I was flashing my firmware yesterday and after flashing the bootrom the PM3 stopped working... even though no errors occurred!

For reference I was following the tutorial here:
https://github.com/Proxmark/proxmark3/w … DC_Flasher

So when going for step 22 the flasher kept waiting for PM3 to show up:

% ls /dev/cu*
/dev/cu.Bluetooth-Incoming-Port	/dev/cu.usbmodem1411

% ./client/proxmark3 /dev/cu.usbmodem1411

Waiting for Proxmark to appear on /dev/cu.usbmodem1411.............[ad eternum]

If I connect the PM3 to my computer, with or without holding the button, the yellow and red LEDs are lit.

Please advise if my PM3 is bricked, and if so, what was my mistake so I can avoid it in the future...

Thank you!

EDIT: For reference here's the version I cloned

Re: [solved] PM3 bricked?

solved with the advice from iceman in this thread:

http://www.proxmark.org/forum/viewtopic.php?id=3203

OP had the exact same problem as I did
