Hi I have a proxmark rdv4 and macos

I managed to run a few commands but i needed to update the firmware to give me access to hf mf ekeyprn d.

I went through the wiki guide here. made and flashed the bootloader and fullimage.elf

sudo ./client/flasher /dev/tty.usbmodem142301 armsrc/obj/fullimage.elf

You can cancel this operation by pressing the pm3 button 

nothing i do seems to fix this, i can no longer run any commands.

can you please help?

When you are coming from a pretty old firmware your bootloader might be outdated as well. Try flashing a new bootloader. In the current (inconsistent) state you probably need to press and hold the proxmark button during the flashing process. And be aware that the Proxmark may appear under a different port now.

and how is it done?

I have a similar problem. Neither flashing a new boot loader nor flashing a new firmware works. In both cases it's stuck at Waiting for a response from the proxmark....

Example output:

sudo proxmark3-flasher /dev/tty.usbmodem143401 -b /usr/local/share/firmware/bootrom.elf

Tried also kali linux but that doesn't help.

How can this be fixed?

I just used the fork https://github.com/RfidResearchGroup/proxmark3 instead and now it works!
