I tried another thing: particle flash --usb CC3000 and I get this response: running dfu-util -l Found DFU device 1d50:607f checking file /usr/local/lib/node\_modules/particle-cli/binaries/cc3000-patch-programmer.bin spawning dfu-util -d 1d50:607f -a 0 -i 0 -s 0x08005000:leave -D /usr/local/lib/node\_modules/particle-cli/binaries/cc3000-patch-programmer.bin dfu-util 0.9 Copyright 2005-2009 Weston Schmidt, Harald Welte and OpenMoko Inc.

@hbierau, put the Core back into DFU mode and run `particle flash --usb tinker`. ---

@hbierau, if I recall, I had that happen to one of my old Cores as well. I ended up introducing it to the garbage can and replacing it with a Photon. ---

@peekay123, that would be my next step as well. Great minds think alike. Thanks anyway, also to @ScruffR [Previous page](https://community.particle.io/t/spark-core-breathing-white/10225.md?page=1)
