Download the Meshtastic firmware packs here:
---> Meshtastic Flasher page Download <---
Plug your starter kit into a Windows PC using the provided USB Cable.
Then double tap reset to enter Bootloader/DFU mode
RAK4631 will appear as a drive on your computer
Next open the firmware pack that we downloaded earlier and locate the firmware similar to this:
firmware-rak4631-X.X.XX.XXabcde.uf2
Copy the uf2 firmware file and paste it on to the RAK4631 drive
Once complete it will likely give you an error, that is ok, just close out of the error. 
Your device should reboot with the latest firmware installed. If your device was previously paired to phones/tablets/pc/etc, you may need to delete/forget the Meshtastic device in the Bluetooth settings, then repair in the Meshtastic app.
For more information on this method of flashing firmware you can visit Meshtastic website HERE.
