    Hello there!
    I have a Lumia 1020 with the windows phone 8.1 developer preview, and am experiencing a problem with my phone. I can't connect my phone to my Windows 8.1 laptop.
    I have tried all of the solutions I found online.
    I can't uninstall or reinstall the drivers as Windows does not recognize the phone, and lists it under "other devices" in device manager.
    I have tried connecting the phone while it is off and have even tried changing the USB setings in the Bing search.
    I guess the only other solution possible is to find the USB drivers and install them manually.
    Can anyone provide a link to the drivers ? I can't find them anywhere online.
    Or does anyone know of a solution to my problem?
    Really guys, I would be very thankful.

    My 620 sometimes gets confused when trying that - power cycling the phone usually sorts it.

    Umm so by power cycling you mean that I should connect it to the charger first and then unplug it and connect it to the computer?

    Switch the phone off and on again and try it when the phone has got to the screen (ie ready to use).

    I had to manually install the mtp driver, dont remember where.

    Since then, everytime i connect the phone, the computer asks ne to reboot.
    It only works once per reboot for me.

    Havent found a solution.

    Im using L 1020 with wp8.1 dev on a w8.1 pc

    Do you remember if the drivers you downloaded were generic MTP drivers, or were they particular to the Lumia 1020?
    Thanks for giving me some hope :)

    I'm also experiencing this. Mine is L620 running WP 8.1 DP

    I've have tried everything from changing the USB cable to hard-reset the phone but nothing worked.

    EDIT : I've also have tried connecting it to another PC but still no luck

    me too have the same issue with my L620, did almost all tips but no luck.Hard reset done about more than 5 times and no count for softreset :)

    battery is so worst irrespective of usage. Mainly it is dropping from 100% to dead over the night.

    Went to Nokia care in India and they said that "we have to wait for official release and they reminded about the warning as well while we install DP 8.1"

    I am pretty much happy if I get this resolved.

    Did they tell you anything about the DP voiding your warranty?

    No ,They did not say anything about that and I dont think it avoids warranty but I am not sure of outside India. I see the phone is in warranty under the Lumia Help +tips

    USB file transfer doesn't work in 8.1 developer preview. At least not on my 521.

    No special drivers are required in any case...it's a standard MTP device.

    Had to resort to connecting my 1020 to an old Windows 7 laptop but at least now I know it wasn't my pc that has an issue.

    I had a similar issue with my device not finding drivers.

    When the phone is connected to your PC restart the phone as I noticed the drivers got installed during the boot-up process

    Which OS does your PC run? I tried this method on Windows 8.1 Update 1, but it didn't work :(

    I also had suffered the same problem about connecting my Lumia to my pc.Tried all measures like signing drivers,updating drivers,installing pc connectivity software downloaded from Windowsphone website and all that.NONE worked.Then I upgraded my pc operating system from windows xp to Windows 7.Since then my pc and my Lumia connect within 3 seconds.Please consider this solution if your pc runs xp

    That is a no-go for me. My laptop runs Windows 8.1. I won't install another OS just to connect my phone to my PC.
    Maybe i'll try it on a Virtual Machine, if it is possible. Anyone have any ideas about that?

    Start it up in safe mode and then go into device manager - you should be able to see things there that aren't visible in normal mode. Remove anything related to the phone and try everything again in normal mode.

    I've got the lumia 625, 1520 and 1020 - all ruining the latest wp8.1 dp - all of them connect to my multiple windows 8.1 machines with no issue, as well as windows 7 and Apple machines (mountain lion)... Can you get the faulty phone working with another machine, like a friend's or a work machine?

    Not to be alarmist but it could simply be the usb socket is not functioning properly. Sadly it happens - the socket on my 1020 went, amazon replaced the device under warranty (I'm in the UK, laws vary etc).

    Perhaps contact Nokia?

    Good luck!!!

    Tried it, didn't see anything new at all. The device manager stays the same with or without the phone connected to the PC.

    I think the problem is with the phone itself. In the phone's USB settings, it simply says "Not connected" even when connected to the PC

    UPDATE : I've went to Nokia Care center, and unfortunately they stated that enrolling WP 8.1 DP will voids the warranty. They also stated that they need the replace the entire phone's motherboard to get it fixed

    I'm really really surprised they told you an officially sanctioned ms update voids the warranty.

    What part of the world do you hail from?

    It is not just him. The Preview for Developers app clearly states that installing the Developer Preview may void your warranty.
    I contacted Nokia India through Twitter and their Support Chat about this issue, and both of them told me that the DP voids the phone's warranty.

    PS. As you might have guessed, i am from India,

    It may differ by region in that case...I have 8.1 on my L620 and according to the warranty check thing in Nokia (now Lumia) Care app, it says i'm still warranty.
