How to reset without data loss

[Martin | Mi 11]

How can I switch to stable without losing and data?

Backup all data, copy personal files to a computer or cloud, since you are already unlocked, you could root even if you don't plan on keeping it later and use a root backup app (like Swift backup, titanium backup) to backup every app with data, switch rom, restore, unroot.

No no no . Please make proper backups. Miui backups ~never brought back app data for some reason.. They seem to only be good for launcher and wifi backups. In this guide I made I have a section about backups and otger related stuff. Please take a look there. I explain many backup strategies there.
