I had everything working for a while last year and then it sat. Long story short, I tried to updated everything today and my Spark 2 now has a white screen after updating the firmware.
When I try to update the boot loader, it fails
pi@brewblox:~/brewblox$ brewblox-ctl particle -c flash-bootloader

It also seems to loop during discovery. I have power cycled and even reinstalled everything
I have tried that a number of times and it still shows the same issue - and the white screen (not the 6 cells that it previously had)
The flash command does complete properly, however
pi@brewblox:~/brewblox$ brewblox-ctl flash

That got me started on the right track. I ended up having to get the app on my phone and once I was able to configure the Photon to be connected to my wifi and phone, everything started to work again. Thanks for your help.
The first step would be to try again with other USB cables. It’s not uncommon for them to malfunction. The fastest way to check is lsusb. A Spark 2 has VID:PID 2b04:c006.
If you get a working cable, then run the bootloader and firmware commands again.
If that doesn’t work, please take an up-close photo of the USB connector component on the board. They are a known weak point in the Spark 2.

It appears I cannot get it to safe mode - only DFU mode when blinking yellow. When I release the service button on magneta it just goes back to blinking blue again. I have tried releasing it immediately when changing or waiting another second to no avail.
