I just did this today. I was coming from Pixel Experience. It's super simple. You will lose all your data.

1. Download the FULL OTA to your computer: (This is a link to global version)
2. REMOVE any security settings you have -- pin, etc. (not sure if this is necessary, but i did it anyways)
3. Reboot to TWRP / Recovery
4. Wipe system / data
5. Reboot recovery again (don't worry if you cannot access the internal storage from your computer, that will get fixed after flashing)
6. Plugin phone to computer
7. Enable sideloading
8. Install the OTA zip by sideloading with ADB
   

   adb sideload OTAFilename.zip

9. Reboot after flash and wait several minutes
10. Done.

I am trying now since 5 over 5 hours to get stock OS for my 7T (hotdogb) with LOS 20 back to stock OS cause of safety net not working as well as some other stuff which i want to reset… But i am unable to install neither TWRP nor default stock OS. I am stuck with LOS recovery and cant install stock OS cause LOS is newer, and it would be a downgrade, letting it fail the upgrade via ADB. I tried with payload dumper and there the partitions are locked even tho oem is unlocked. I ran out of ideas, anything I can try?

Regarding TWRP: i tried both stock and other rom version, it did not work.
