I've downgraded my phone to A11, then updated it to A12 using this full zip and then used OTA to get C.20.
As i mentioned this full zip is EU version. If you have a global or IN version i am not sure it will work.

If you're already running C.15, you can simply use Settings>System settings>Backup and reset>Reset phone>Erase all data. This will wipe /data (wipe all apps and all user data) leaving you with a clean install of C.15. If you're rooted, you'll keep root but will need to set up the Magisk app again.

My personal preference for backing up is:
- Swift Backup (available from Play Store) for backing up apps and their data
- ADBsync sdcard Backup from https://forum.xda-developers.com/t/...-and-ends-multiple-devices-platforms.2239421/ for backing up and restoring data from /sdcard to PC.

By sdcard backup you're referring to the internal memory backup, right? Is there a guide for using ADBsync to backup all data there? Thanks!

any way to restore the old advanced display slider. i had it set just right and the new 12 only has a warm / cold option i hate it. color os made the screen very washed out looking like reds are more maroon. hard to explain. i used msm to go back to 11 and the screen looks awesome again. the phone keeps annoying the crap out of me to now update to 12 again even though i turned it off and then selected not to notify me. so freaking annoying.

I have already downloaded this and tried to flash it using local upgrade but although the zip is in the root dir it won't appear on the local upgrade. Maybe is an older version or a corrupted file, also the file name should be something like KB2003_11.C.16 instead it's OnePlus8Oxygen_15.E.16_OTA_1036.

Update:
I was confused with another site, this is the file that stops downloading midway (usually when it reaches 2.5GB)
