    Still waiting for MS to release the CYAN update OTA for us on Dev Preview so we'll know if it fixes this issue.

    I am pretty sure now that it is a hardware issue.
    Last time I tried to connect the phone to my laptop (Win 8 Home, USB3 ports, stock cable) it started to loop on the unrecognized hardware and didn't even charge.
    If I connect it to the wall, they it charges just fine, but there is no way I can make my PC recognize it and I tried all the "solutions" posted in this thread. I think I'll buy the app I mentioned earlier, that way I can backup all my files to my PC without the need for a cable.

    /sighs, it is quite disappointing. Having such a great phone with such a great flaw.

    If your operating system did not come with Windows Media Player, install the Media Feature Pack for your version of the operating system.
    Get Windows Media Player - Microsoft Windows

    Use the USB cable that came with the phone.
    Connect the phone to the PC. Turn it all the way off, hold power button and slide the screen down. The phone will turn back on and it will be detected, drivers should load.
    You should see it in windows explorer. It should install in 'portable devices' in the device manager.

    Problem is:
    "Included in Windows 8 and Windows 8 Pro"
    "Included in Windows 8.1 and Windows 8.1 Pro"
    My laptop came with Windows 8 Home edition ahd I updated to 8.1. I bought it in the US so I know is not an N or NK Windows edition. I checked the about and I have WMP 12.0.9600.17031 so yeah, I have the Windows media player and the feature pack. because they come with the OS

    Use the USB cable that came with the phone.

    Tried to turn it off and connect (basically the same thing) I've used stock cable, original nokia car charging cable, original nokia power bank cable, samsung cable, HTC cable, a thread with 2 plastic cups on each end, nothing works.

    I give up. I give up.

    Trust me, it's not the drivers - nor Windows 7/8/8.1. Like I said before, I tested my 1020 on 3 different machines, with newly installed/formatted Windows OS'es. -each time it manifested the same "USB not recognized" issue. The problem is the phone itself. Somehow the DP installation corrupted the USB drivers in the phone itself.

    I couldn't wait any longer for the CYAN update. I was hoping the release of the CYAN firmware for the DP users would come sooner and fix this issue. I brought my unit to a Nokia Care Center last week. I got a call yesterday that they replaced the mainboard of my 1020 free of charge. (My unit is till under warranty). I will pick it up tomorrow.

    Good luck guys! Here's hoping I don't have to come back here and get the same issue...

    Same here. was getting repeated 'USB not recognized' errors. took it to Nokia Care, they replaced the motherboard. works like a charm now :)
    PS: Nokia has a 24 month warranty so all 1020s should still be covered under it.

    Thanx for the heads up.
    I don't think there is a Nokia Care Center in my country, but maybe the carrier covers the warranty.

    Hi,
    Sorry to hear that. In my experience the only solution is to send it back to nokia. I'm quiet sure it's a hardware problem because everything goes fine after having it fixed.

    Hi all,

    The answer to what's happening here is very simple. It's not your Windows Phone software, it's not your desktop Windows and (partialy) it's not your USB cable. It's just a simple physic matter.

    I own a Nokia Lumia 1020 since 2013, the one with 64 GB of storage. When the phone starts connecting and desconnecting loop, that means that the microUSB of the phone was damaged. This was happening lately to me too, and from the attachedlumia-1020-damaged-microusb.jpg photo you can clearly see that the real microUSB connector is slighty backward inside the metalic hole that is with the case, like if someone would have pushed it. Well, in fact that "someone" is you and why this happens?
    Well, after opening and dissasemble 4 times the phone for microUSB replacement, I can assure you that this happens due to 2 facts:

    1.- The microUSB quality of the Nokia Lumia 1020, remind me the bad quality of that same port used in the Nokia N900. With that phone (Nokia N900), you have to use a special microUSB cable with the downside fangs (that are used to maintain connected the cable to the phone) the softer posible you can get, because if not, even using the official cable, it will broke internally, making it impossible to connect again (the only way was to weld it again by yourself). You can check this kind of problem in some N900 forums (http://talk.maemo.org/showthread.php?t=75920).
    In this N900 case, the problem was when you pulled the cable from the phone, but in this current case (Lumia 1020) is that you are pushing it inside the phone little by little. And how is it you should ask...? well, get 3 or 4 microusb cable used for charging or for data and observe that the metalic final part (the one that goes inside the phone) doesn't have the same lenght. It slighty differs from one and other. That take us to the second fact:

    2.- You, or anyone that used the Nokia Lumia 1020, used a microUSB cable, for charging or to transfer data, that had LONGER metalic connector that the space the phone has to allocate it. With the time, that make the connector to get backward little by little, and get us to the day that it will only charge and nothing more. But, why it would be still charging and pseudo connecting to the computer? well, that's due to the USB design.
    Check this USB diagram: https://i.pinimg.com/236x/1b/55/53/1...c10c3b7257.jpg As you can see, the data connectors are slighty backward compared to the power connectors. You can check that this is true in any USB cable. Well, this is an old USB A diagram but the connectors used for data in a microUSB are also slighty backward with one difference, the microUSB connector has 5 pin connectors instead of 4 as you can see here (https://i.pinimg.com/236x/a7/c1/02/a...f--samsung.jpg). The fourth pin connector is not as back as the data connectors and enough to connect to the USB port, starting the connection that can not be completed due to the fact that the data connectors are not touching those inside the phone microUSB.

    To sum up. You have two options here:

    1.- Replace the damaged microUSB with a newer one and don't lend the phone to your childs (my case) that will connect any cable with any imaginable force.
    2.- Open the phone and put some kind of glue or silicon just before the microUSB connector, so it won't be able to be pushed back again with any kind of microUSB cable.

    That's all.

    Regards,

    Akuma.
