Issue with Flashing - does not work - devices seems bricked

[Axlbuld]

Hi,

I just pulled the latest version and tried to flash it onto a proxmark3 easy as well as my proxmark3 RDV2 (before trying the RDV4). However, I have severe issues:

• flashing the bootrom works
• flashing the rest fails after one line of dots. Afterwards, the proxmark3 won't boot. It does not show up on ttyACM0 anymore.

I tried the master as well as iceman fork. no success. I have found some very old very small special firmware (LF-standalone). That was mostly the only I could flash successfully afterwards. However, I had to hold the Button for more than 10 Seconds to get it into DFU mode and keep it flashed until the process has finished. I have to follow this procedure for bootrom and fullimage.

Now, I was able to flash an older icsom-fork image onto the RDV2 and get it to work (however, LED CHR is constantly flashing red). I am using kali rolling 2.0, just updated and upgraded.

Any idea? Where did I fail?

Found the issue - thanks to a friend. It stil is the ModemManager on Kali. Eventhough I have created the blacklisting entry suggested, it still interferes and resets the device (the old PM3 RDV2 is clicking every 20 seconds or so). ModemManager killed, works fine.

And how did you kill the modemmanager? Update Wiki for Kalli?

Sorry, forgot to write. As I don't know what the ModemManager is used for, I left it installed. I did not kill it permanently. So, just plain commands: ps -aux | grep ModemManager kill [pid] - on my system stable 521

I know, it is not permanent and not intelligent or sophisticated, and you have to do it everytime before use. apt-get purge ModemManager might do a better job as it is permanent, but I don't know, what I will break with that.

@Iceman: do you update the wiki? I am quite new to the github stuff and a bit preoccupied to break stuff. And thanks for the good work.
