    Please help me with the downgrading process in OnePlus 6 as the stable update of Android 10.3.0 is still not stable for my device.

    Problem in Android 10 - A lot of heating, battery loss, Camera sometimes doesn't open, gallary doesn't work properly.

    thanks.

    You need the rollback ZIP.

    Hi
    You must save important files, this process will erase all your data
    Suggestion: first try a factory reset

    Since downgrading from Android 10 to Android 9 will wipe your phone, why not do a Factory Data reset, as @Cervantes suggests, on your existing Android 10 first and check out if your issues persist.

    DOWNGRADE FROM ANDROID 10 TO ANDROID 9

    You will need to use the roll-back firmware which will wipe your phone and downgrade you to Android 9.

    See downloads and instructions for both OnePlus 6 & 6T, rollback firmwares...

    [GUIDE] Rollback/downgrade from OOS Android 10/Q to stable 9/Pie

    You can then download the the latest Android 9 stock Oxygen OS from here to upgrade to the most recent Android 9 release for the 6 & 6T by using Local Upgrade on the phone.

    You cannot downgrade with the local update
    You are changing the system, so you have to clear the data and cache memory

    Did you follow ALL of the steps provided by @ironass? You cannot skip any. If you followed all of the steps faithfully you shouldn't be having that problem. Shortcuts not permitted.

    Yes, I have followed all the steps except doing Factory Reset at the beginning. Do I have to factory reset first?

    You seem to have quite a mess. I do not understand why users are so reluctant to reset their phones. If you followed all of the steps the first thing you did was a backup... so you have all of your data. With a reset you're beginning with a clean start.
