Updating the firmware

Before starting, make sure that your Meteor Pro remains connected during the entire flashing process.
Interrupting the connection during an update may cause the device to enter an undefined or unrecoverable state.

Step-by-step procedure:

Connect your Meteor Pro to your computer using the supplied USB-C cable.
Open a browser that supports Web Serial (such as Chrome, Edge, or Opera).
Go to the official Meshtastic Flasher website: https://flasher.meshtastic.org
In the device list, select NomadStar Meteor Pro.
Choose the latest stable (Beta) firmware version available.
Click “Flash”.
On the next page, click on "Enter DFU".
A USB storage device named "RAK4631" should appear in our filesystem explorer on your computer.
Back to the flasher, click on "Download UF2".
Copy the UF2 file downloaded on step 9. and copy it on the USB storage "RAK4631".
Wait for the USB "RAK4631" storage media to disconnect by itself.
Once the USB storage "RAK4631" disappeared, you can safely disconnect the Meteor Pro from your computer.

Important notes

Do not disconnect the USB cable or close the browser during flashing.
Ensure your computer remains powered and does not enter sleep mode.
Only use official Meshtastic firmware or firmware verified by Nomadstar SARL.
