Do I need to flash a ROM to use the beta?

Is there a way to use the beta workout losing your data? [MI 9SE]

As far as I know, no, wiping your data is mandatory because of how files are managed in the different ROMs

You can try to dirty flash the weekly ROM but if your device doesn't boot to system after that, you can still reflash your previous ROM (Stable one) then use, at your own risks, my "Stable to Weekly" boot patch - BE SURE TO READ EVERYTHING BEFORE USING IT => https://xiaomi.eu/community/threads...t-were-shipped-with-android-9-or-below.58318/
