CE image install on SG-1000

[rb_telit]

I bought a SG-1000, it comes with the release version of 2.4.2 installed on it.
I am trying to reinstall with the CE development version but it will not boot from the mem stick nor a microSD card:
I tried to image the mem stick adn SD card from Mac OS using DD and from windows using Rufus, neither work.
It it wont boot from usb or SD, it boots from on-board mmc.
I did notice that on the release recovery image it creates a FAT partition that the CE editions do not have.

Any help would be appreciated.
Thanks!

Below is console output of trying to boot from CE image on usb stick:

You cannot use CE image for SG-1000, it's for x86-64 architecture. Download the SG-1000 ARM based image from portal.pfsense.org. If access to your portal expired after first year, it will be renewed automatically. Let me know if that's not the case.
