    I successfully updated to Win 10, now there are few problems that I am facing.
    First - Very slow phone performance
    Second - Flight mode and Mobile data options does not work
    Third - Camera freezes
    Fourth - SD card needs frequent checking
    Fifth - Seems I am yet to encounter many more

    I regret updating to Win 10
    Any help regarding these issues

    PS- If I use windows recovery application, can I revert back to Win 8.1 Denim

    A hard reset may solve some issues. Otherwise you can use the Windows Software Recovery Tool to roll back.

    Are you sure the windows recovery tool will work, moreover the recovery app starts downloading software package of around 1.5 Gb, isn't that too much of data for Win 8.1 Denim

    Windows 10 is not finished. You should've read before jumping in blindly.

    New Windows 10 Technical Preview build now available for phones
    Look at the known issues section. It's all there.
    512 MB devices will sometimes have app crashes. Those two cellular toggles are broken, etc.

    If you wanted a final product, you should've waited. Best you revert to 8.1 and wait for a more finished build of 10.

    Flight and data mode toggles were listed as known issues that wouldn't work on this build.
    Some people suggest a hard reset/creating a dummy access point might help.

    It's a technical preview man. That's the point of releasing it to the interested public so that Microsoft will know all the problems and work on fixing it for a perfect and smooth "official release".

    There are many things broken, you should've read what was up with this, because this isn't just some normal polished software update that some seem to think it is. It is NOT complete, it is NOT for normal use on a daily driver. It is experimental or alpha at best.

    Now take that phone to the Recovery Tool and downgrade to the current version until they release something that's not an Insider build.

    Finally reverted back to Win 8.1 Denim. It took hell lot of time for the windows recovery tool to download the package and the download speed never went above 107 kbps, took almost 6 hours, but now Lumia Denim feels so much like back home

    In case windows 10 is not finished, updates to windows 10 should be avoided by mirosoft itself.

    Was able to download, but now facing many issues. Planning of doing factory reset.
    1) wifi / mobile data not working
    2) contents on Sd card not accessible.(music/Photos)
    3) Phone is very slow


    I trust Microsoft if it provides an update it should be compatible.
    If a issue is known , update should be prevented.
    I do agree argument since it is not a final release these things are expected.atleast prevention would be better then cure.
