Hello all!
Hope that's the right place to post that question
i want to downgrade my phone from android 12 to android 11 (Asus rog phone 5) because it's very unstable.
i read on the google site that the google auto-backup doesn't support downgrading, so i need a recommendation for software from someone who downgraded his/her phone to a lower version and managed to restore it later on.
Also is this process dangerous? I read the manuals on Asus official site which just talks about backup the phone, then downloading some file from the site restarting the phone and it should install it alone.

Thanks in advance for helping!

As a thumb rule, it is always risky to restore a backup of settings between versions, especially when downgrading.

Any tips or ideas you can share? I must downgrade because android 12 really did a number on my phone

If I were you, I would not backup anything and install everything manually and configure. Whatever you do, please do not back up Android 12's settings and restore them in Android 11.

Third party apps can be backed up using Titanium Backup or some similar backup tools. While restoring them, go by one app at a time so that you will know which app's backup caused issues and you can avoid restoring that app the next time.

Do a manual backup of all your personal stuff. Downgrade (A12 > A11 is really an 'upgrade' ). Then do a clean A11 setup and transfer your files over. Old school but the most solid way...

i guess i will make a combination to both
backup some apps with titanium backup (other will be downloaded normally after downgrade)
backup files from files manager through local backup connected to pc
will not backup any setting (maybe will screenshot to restore them manually)
will disconnect google from the phone
download the android 12 to android 11 from the asus site
and hope that anything that was ****ed will be normal again.
will let you know later how it went.
thanks guys.

Any recommendation for backup app for applications that doesn't require root?

TNSMANI said:

If you mean that you are unrooted, then the options are limited. Certain backups require root. ADB backup & restore can also be used.

You can check up this thread: https://forum.xda-developers.com/t/need-recommendation-for-a-backup-restore-app-no-root.4401711/ and search in Google.

Please explain what is adb backup? Is that an app or a method?
Can't find a correct reference to said name

Also, does that back up app data? Is this works for downgrading?

It is a method to backup and restore using adb commands. It is partially explained in the link that I provided. You can also google adb commands to learn further.
