[SOLVED] Flashing to newest firmware issue


I was trying to to flash the PM to the newest  version from RRG\iceman repo,  however I got the following:

[!!] Note: Your bootloader does not understand the new CHIP_INFO command           
[!!] It is recommended that you first update your bootloader alone,           
[!!] reboot the Proxmark3 then only update the main firmware 

After searching, I tried flashing the booloader alone and it was successful. However, when I tried running the client I got:

 unknown command:: 0x61334d50[!!] ERROR: cannot communicate with the Proxmark 

I realized later that the device is not enumerated correctly and it gets disconnected even though I removed ModemManager. After searching here and there I tried button trick to flash the device as follows:

  1. press button and keep it pressed (IMPORTANT)

  2. plug in device

  3. run flash command sudo client/flasher /dev/ttyACM0 armsrc/obj/fullimage.elf

  4. wait until flash is finished.

  5. release button.

And the method was successful, but when I unplugged and re plugged it again, ran the client, it could not find the device on the port. So I checked, the enumeration problem still presists.

What am I missing here or doing wrong? yikes

I need help as this is maybe the third time this happens.  yikes

Your help is much appreciated. Thanks! big_smile

Re: [SOLVED] Flashing to newest firmware issue

That would be the correct way to update it.   However did you compile the repo for your device?  If you have a RDV4, nothing extra to do,   if you have other proxmark3 device you will need to follow instructions …

If you feel the love,
