    Hello!

    How can I downgrade my OnePlus 7 (EU variant) from OxygenOS 10.0.3 to 9.5.8? I'm having delayed notifications issues and problems with Bluetooth earphones as well as battery drain so wish to downgrade. I'm non-rooted and fully stock.

    Thank you!

    I've already tried that I'm afraid and am still experiencing the same issues :(
