Hi, My photon bricked after an upload, I did all the steps to reload bootloader and system but it remains with yellow blinking and D7 on.

You have the _“bluetooth”_ tag added to this topic, but the Photon doesn’t feature an inbuilt bluetooth module - can you clarify? Can you try `particle update -v` again and post the full output? ---

OK, in this case you may need to download the individual binaries from here [https://github.com/particle-iot/device-os/releases/download/v1.5.0-rc.2/particle\_device-os@1.5.0-rc.2+photon.binaries.zip](https://github.com/particle-iot/device-os/releases/download/v1.5.0-rc.2/particle_device-os@1.5.0-rc.2+photon.binaries.zip) unzip them and apply them like this (in Listening Mode) ```nohighlight particle flash --serial photon-bootloader@1.5.0-rc.2+lto.bin -v ``` (in DFU Mode) ```nohighlight particle flash --usb photon-system-part1@1.5.0-rc.2.bin -v particle flash --usb photon-system-part2@1.5.0-rc.2.bin -v particle flash --usb photon-tinker@1.5.0-rc.2.bin -v ``` ---

Could it be that the SETUP button has go stuck? You can find out with a multimeter and measuring the voltage between GND and the pad number 26 on the bottom of the Photon ![image](https://us1.discourse-cdn.com/flex026/uploads/particle/original/3X/2/1/21252b80b12dee6e7b86df53963f622021e27388.png) It should read 3.3V - if it’s 0V this might be the problem. ---
