Heat not working after new Wi-Fi

I installed my T-stat about two years ago, and everything has worked properly, heat and A/C. I recently changed my internet service so I have to re-setup my t-stat. Problem is, I have no idea what wires my old t-stat from two years ago had at this point. I cant get it set up now regardless of what color I choose in the setup. I did install the c-wire adapter. Like I said, it all worked until I had to reset it up and dont know what wires my old t-stat had. How do I figure this out?

share pictures.
even just pictures of your old wyze setup are sufficient.
