    Hello, I'm just upgraded from oxygen 9.0.9 to Hydrogen Betab30 (Android 10). But I can't downgrade to Oxygen from local system update.

    I want downgrade, because 4G network issuses and can't login to OnePlus Cloud account (China Version maby )

    There is another way without PC do do that.Because my Windows 10/PC can't see Qualcom drivers on fastboot mode?

    Maby wait oxygen Android 10 version and I upgrade without issues?

    Thank You!

    You have to use the rollback package from the DP build thread. And it will wipe all the data. So backup.

    And next time, do a proper research before changing rom.

    Where have you been since morning? Knew only someone like you could help him. This is exactly why I resisted the temptation to install the H2OS build.

    Talking of installing ROMs and all that, once the new beta arrives ( Android 10), should I first wipe and then install or can I first install and then format?

    That's a special build for rolling back from Android 10 to Android 9. But it is built for OxygenOS. Guess it should work for rolling back to HydrogenOS as well.

    Honestly, I have never wiped after any major update. I just think it is a myth. But if it gives you any solace, a wipe after update is better.

    Try the msm tool then. Google it.
    Anyways, you can't rollback without a wipe.

    You don't need a PC with the rollback package. Just backup your files to a drive and install the rollback package using local upgrade option.
