Aha, Thank you so much for that info
So Sounds like
1) we get the cable from Ebay or some site so we can connect to the vehicle with the laptop running chrome browser.
2) Get the Matrix Headlight USED Or New (For My Case Model S/X) Refresh
3) Question - Do we need any special adapter or make one or are they pretty much Just Plugs and mounts the same way ? For the 2021+ Refresh.. Headlights
4) Get the Subscription for Say Just a Day and cancel..for $165 for the toolbox 3

5) Follow instructions the one you provided after connecting the cable to laptop with chrome browser with the right cable.

2. click
Service Shell from left pane
3. enter command
gw-diag SET_CONFIG_DATA 00 28 2
4. enter command
reboot-gateway
5. from vehicle, enter service mode and press Reinstall Firmware button
And that should be it .. Correct for Model S/X refresh ? Am I missing anything sorry the reason I am asking this want to make sure If I end up trying this I have everything I need..
