When using [setup.particle.io](http://setup.particle.io) for a Photon, the default OS installed is 3.3.1. Is there any way to modify this Device OS version - say to 2.3.1?

It is not possible to change the Device OS version.

However, [setup.particle.io](http://setup.particle.io) is only intended for setting up individual developer devices; there are a number of other tools for onboarding device fleets that do allow the version to be set.

If you already have the firmware you want, you can just use the Particle CLI. Just pass the Device OS version you want as `--target`

```auto
particle usb dfu
particle flash --local --target 2.3.1 firmware.bin

```
