Brand new Photon, right out of the box - can’t connect it to the cloud. Blinking cyan with red flashes. The Tinker app setup fails Using the CLI (on Mac running for 10.11.2) for USB setup fails Then I’ve done: Manual Firmware Update, following instructions here: https://docs.particle.io/support…

Solved!! Though I had previously flashed the server key to the device, I did it one more time, on mdma’s suggestion, after running the keys doctor command and voila!! Connected, claimed! I have indeed won the internet. Thanks so much, everyone in this thread, for hanging in there with me.

Thanks so much, but the solutions from that thread did not work. I put the device in DFU mode and pasted in the device id with this command: particle keys doctor paste-device-id It failed and I got this message: dfu-util: Invalid DFU suffix signature dfu-util: A valid DFU suffix will be required…

Just out of curiosity How often have you replaced your Device ID in the output pasted there?

Just once. Well maybe twice - I inadvertently ran the “paste-device-id” command without the Device ID number and got the message below. Then I ran it properly and got the message above. *************************************************************** Warning! - device id was shorter than 24 chara…

Hmm, it still doesn’t make sense tho’ I think you are misunderstanding the suggested command line It’s not meant to be particle keys doctor paste-device-id 3D0020000347343339373536 but particle keys doctor <replace-this-with-your-device-id> so in your case particle keys doctor 3D0020000347343…

Well, that could be. I think I used your second command there, but I might not have - command line still somewhat new to me. I’ll try again. Thanks.

Ok I ran the key doctor command while in DFU mode, $ particle keys doctor 3D0020000347343339373536 got this: running dfu-util -l Found DFU device 2b04:d006 running dfu-util -l Found DFU device 2b04:d006 running openssl genrsa -out 3D0020000347343339373536_rsa_new.pem 1024 running openssl rsa -in …

From the above, this seems significant: attempting to add a new public key for device 3D0020000347343339373536 Error sending public key to server: Permission Denied Make sure your device is in DFU mode (blinking yellow), and that your computer is online. Error - undefined
