Hello @feroxktm,
after a factory reset I’m having similar problems, mainly the solid magenta error.
I can put the Core in DFU mode, but the CLI cannot detect the Core:
>particle flash --factory tinker
Apparently I didn't find a DFU device? util said dfu-util 0.8
Error writing firmware...no dfu device found.
I think the problem may be a missing driver, where can I find the DFU driver you are referring to?
My Windows 7 Devices list shows a “CORE DFU” without a valid driver installed.
So I can’t flash my Core and install the updated firmware. And I can’t connect to the cloud. Help!!

EDIT:
Why is Google so great…?
I found this: [Installing DFU driver][1]
So I could install the DFU driver and now I can flash from USB a new firmware
>particle flash --usb deep_update_2014_06
But I can’t find the .bin file anywhere on my PC nor on Github!
It is missing
No such file or directory: Could not open file binaries/deep_update_2014_06.bin for reading
And this post does NOT help: [deep-update-source-file-for-spark-cli][2]
as the Github link does not work!
OK, I had to re-install the CLI (update did not work):
I reply to myself…
I have a solid magenta on my Core again!
I can connect through serial and configure the WiFi, but after rebooting I get the solid magenta again.
I tried to update the firmare with
particle flash --usb deep_update_2014_06
but, even though the DFU device is apparenty recognized by Windows, I receive this error:
Apparently I didn't find a DFU device? util said
Error writing firmware...no dfu device found.
What do I do now? Should I reinstall the DFU driver?
I’m discouraged!
Andrea
EDIT:
I installed the CLI again, the DFU driver again and finally managed to flash the firmware with:
Anyway I still had problems connecting to the WiFi AP (Linksys or Android phone), I have a flashing green after any reboot/reset, so I also did:
particle flash --usb deep_update_2014_06
Then a partial success: I could configure SSID and password, had a flashing magenta, but at the end flashing blue again! I can configure the AP details from the serial, but then it goes back to flashing blue again!!
HELP! Is my Core at the end of his life?
