google lens or something I will upload pics though)
5. Wait till all
ont led start flashing, look in the window (the status one) you opned earlier once flashed it will show green checkmark (during flash it will show downloading like icon)
6. Once flashed ont lights will become stable (all lights will keep glowing stable) wait for a few minutes (about 1-2 mins there is no fixed timing) then power reboot ont (means replug power)
7. After reboot connect using telnet to ont ip (whatever you are using eg 192.168.100.1 or 192.168.1.1 basically you can check from network settings the gateway ip)
