    hi there,

    anyone can suggest how to make a clean flash of OnePlus OS. Usually we are doing it by local upgrade method.

    while using Xiaomi for long time, I found the way of local upgrade. sometimes, through local upgrade, all features are not functioning properly or few features are missing or behaving like old.

    Xiaomi has a tool like Mi Flash by which users can make a clean flash of the latest update full OS. sometimes it's needs to unlock bootloader, there is option or tool for unlocking or relocking bootloader. for OnePlus, I also don't know if there is any necessity of unlocking bootloader for clean flash and how to do that.

    anyone can advise, share links or threads for above, will be highly appreciated! thanks
