That's an important piece of info. If you are updating an Argon from anything before rc.25 to rc.25 or above, you also need to update the NCP (Network CoProcessor).  
For that you need to download these files

- [https://github.com/particle-iot/firmware/releases/download/v0.8.0-rc.27/system-part1-0.8.0-rc.27-argon.bin](https://github.com/particle-iot/firmware/releases/download/v0.8.0-rc.27/system-part1-0.8.0-rc.27-argon.bin)
- [https://github.com/particle-iot/firmware/releases/download/v0.8.0-rc.27/tinker-serial1-debugging-0.8.0-rc.27-argon.bin](https://github.com/particle-iot/firmware/releases/download/v0.8.0-rc.27/tinker-serial1-debugging-0.8.0-rc.27-argon.bin)
- [https://github.com/particle-iot/firmware/releases/download/v0.8.0-rc.27/bootloader-0.8.0-rc.27-argon.bin](https://github.com/particle-iot/firmware/releases/download/v0.8.0-rc.27/bootloader-0.8.0-rc.27-argon.bin)
- [https://github.com/particle-iot/argon-ncp-firmware/releases/download/v0.0.5/argon-ncp-firmware-0.0.5-ota.bin](https://github.com/particle-iot/argon-ncp-firmware/releases/download/v0.0.5/argon-ncp-firmware-0.0.5-ota.bin)

And then you need to perform these commands in order  
In DFU Mode (blinking yellow)

```plaintext
particle flash --usb system-part1-0.8.0-rc.27-argon.bin -v
particle flash --usb tinker-serial1-debugging-0.8.0-rc.27-argon.bin -v

```

In Listening Mode (blinking blue)

```plaintext
particle flash --serial bootloader-0.8.0-rc.27-argon.bin -v
particle flash --serial argon-ncp-firmware-0.0.5-ota.bin -v

```

For the Xenon you do respectively

- [https://github.com/particle-iot/firmware/releases/download/v0.8.0-rc.27/system-part1-0.8.0-rc.27-xenon.bin](https://github.com/particle-iot/firmware/releases/download/v0.8.0-rc.27/system-part1-0.8.0-rc.27-xenon.bin)
- [https://github.com/particle-iot/firmware/releases/download/v0.8.0-rc.27/tinker-serial1-debugging-0.8.0-rc.27-xenon.bin](https://github.com/particle-iot/firmware/releases/download/v0.8.0-rc.27/tinker-serial1-debugging-0.8.0-rc.27-xenon.bin)
- [https://github.com/particle-iot/firmware/releases/download/v0.8.0-rc.27/bootloader-0.8.0-rc.27-xenon.bin](https://github.com/particle-iot/firmware/releases/download/v0.8.0-rc.27/bootloader-0.8.0-rc.27-xenon.bin)

In DFU Mode (blinking yellow)

```plaintext
particle flash --usb system-part1-0.8.0-rc.27-xenon.bin -v
particle flash --usb tinker-serial1-debugging-0.8.0-rc.27-xenon.bin -v

```

In Listening Mode (blinking blue)

```plaintext
particle flash --serial bootloader-0.8.0-rc.27-xenon.bin -v

```

You shouldn't need to unclaim/reclaim the devices, you can just set them up as if they were new, even if they are already claimed to your account.
