Nest learning thermostat reset

[Cecil4500]

I purchased a nest learning thermostat and after installing it 3mos later I ended changing internet providers, so the wifi changed. I forgot the 4 digit pin I that Ihad placed on the thermostat & couldn't access settings to change the wifi. In my frustration, I thought that maybe if I deleted the thermostat from the app, that maybe I could reinstall it & start fresh. Well that didn't happen. Now I have a locked thermostat whose settings are on eco mode & l can't use. Can someone please help me on how I can reset it?

If you can't control it using the app anymore, you'll need to reset it using a computer.

1. Connect the Nest Thermostat display via USB to a computer.
   
   
2. Verify that the Nest Thermostat mounts (appears as an attached drive icon).

• If the Nest drive will not mount: Restart the thermostat and the computer.
• If the Nest drive still won't mount: Connect another device to the cable to see if it appears as an installed device.
• If it doesn't appear, use a different cable/port/computer.

If the Nest drive is successfully showing up on your computer, can you see a technicalinfo.PLIST file? If you get this far let me know and I'll ask a community specialist to assist with next steps, as these can't be shared publicly in the community.
