Downgrade rooted device from Android 11 to Android 10 without data loss

[slvrhwk]

I upgraded to Android 11 (Oct 2020 stable) a couple of days ago. I have never been more disappointed in an Android release. My phone freezes constantly and the only way out is a hard reboot. Sometimes it takes 5-6 reboots before the phone behaves normally. There are lots of threads on Google forums where people are facing the same issue on different pixel models, so it looks like an issue with the OS and not the phone. I would like to go back to Android 10 and preferably save my data. I have a rooted phone. Can I follow the same steps that I performed to upgrade - https://www.youtube.com/watch?v=fYib1WNr2I8?? Thanks!

No, downgrading requires a wipe (factory image with -w intact).

I am assuming you are rooted? Are you using systemless hosts module and Adaway? That causes what you are describing...there is a bug in one of them.

Uninstall Adaway and the Systemless Hosts module if so.

Yes, I'm using Adaway and Systemless Hosts module. Cool, I'll delete it. Any other way to run adblock currently?

Thanks a ton, btw! This really helps!

Edit: I uninstalled Adaway. But I'm running the canary version of Magisk and when I go to settings, there's no option to delete Systemless Hosts module. There is a button "Systemless Hosts" and when I click on it, it says 'Added systemless module for adblock apps'. How do I delete it?

One way to delete it would be to create a file called remove in the systemless host directory in /data/adb/modules/, and reboot. I don't have that module, so I don't know what the directory name is.

An alternative to AdBlock is Settings, Network & Internet, Private DNS. Set Private DNS provider hostname to dns.adguard.com.
