Hi everyone,
i'm having difficulties to connect my sgs2 to a pc.
i have tried it on 3 different machines (win7 64, win7 64, winxp 32) with the same problem:
I works fine when i first connect the phone in download mode. But as soon as i disconnect the cable i can't connect it again. Windows sais that it doesn't recognize the device and that's it. The device manager shows an "Unknown Device" under USB-Controller. And i am not even able to install drivers by manually pointing windows to a file.
as already sais, i have tried that on 3 different machines. I have tried installing driver via kies and via the driver file that is available here in the forums. i have also tried different usb ports.
Any ideas?
Goddchen
EDIT: Maybe this is an important information: the phone connects fine as long as it is running (can be found via adb, logcat is working, etc...) it only makes problem when in download mode...
I had exactly the same issue yesterday on my Windows 7 box. In the end I connected the phone in normal (not download) mode. Into device manager and uninstalled the drivers through there.
Then I uninstalled Kies and reconnected the phone, I allowed Windows to search windows update to find drivers (not that it did as it couldn't find any and reverted to the local ones. Then disconnect the phone, re-install Kies, run the install drivers from the tools menu, close Kies. Run up Odin and the connect the phone in Download mode, low and behold 2 minutes later after a lengthy installation process the phone was picked up.
I tried a number of things but for some reason this specific order seemed to sort it.
Hey,
thanks for you hints. But they didn't work for me.
I found the problem: believe it or not, it was THE CABLE. I went and got another cable and this one is working fine all the time. The other one doesn't... Very strange...
My computer connects fine to my Z2 tablet via usb, both when in mtp-mode as well as in mass storage mode. I can browse the content the tablet via computer.
However Sony's own software, the pc companion can't find the tablet at all. There is no error message, just a complete blank when it is searching for the tablet.
I'm running Windows 7 and have tried uninstalling, reinstalling both the software and drivers but to no luck.
Anyone else with this problem or suggestion how to solve it?

I couldnt get it to work either, tried everything, even wiping the tablet.
However what worked for me was connecting the Tablet through wifi. With that I could see the tablet in PC companion, however I still cant get USB connection to work. So try Wifi?
I had the same problem. Could fix it this way:
plug in usb-cable only to your computer
start connection-progress within the software
plug in the other end of the usb-cable when prompted to connect your computer and tablet
voilà!
I never imagined, the connection-order of the usb-cable would make any difference, but it works now (whyever).
If it doesn't work for you, download, install and run the update service (http://www.sonymobile.com/global-en/tools/update-service/), follow the instructions until your computer installs new drivers (don't wipe your device and don't apply any update, just abort the progress at this point) and try again the steps above.

Tried the above and still no luck.... Does anyone have any other suggestions? The tablet is recognized as a MTP device but will not connect to PC Companion. Ironically, when I first downloaded PC Companion, it did briefly connect to the device but it looked like additional windows drivers may have installed (?). I abruptly lost connection and have not been able to get it back. Any help would be greatly appreciated. Thanks
I had same issue as u. I fixed it like this: I switched to a laptop that had windows 7 running on it instead of windows 8. Uninstalled pic companion and redownloaded from Sony site. And installed. I reset the tablet. After reset done. I ran the pc companion then I connected my tab to laptop USB. And now after 15 sec my tab was recognized and prompted for the. 402 update. That is how I fixed it.

So I picked up my Verizon LTE Xperia Z2 the other day SGP561, and am having the same issue with not being able to connect the PC Companion. Every time I try to "pair" it with my laptop (running Win 8.1) the PC Companion app tells me the pairing has failed, try again.
I've uninstalled the device from the computer, uninstalled PC Companion, factory reset the tablet, re installed the PC companion and tried again. Every time, it gives me the same error, and just will not pair.
Instructions from Sony
I just had this issue, I assume you solved it but someone else might end up here looking like I did.
These were sent from John @ Sony support for the Z2 (Works for other models too though).

Hi KapaiKiwi,
Thanks a lot for your instructions. After to navigate through the web whithout success (and reading very strange solutions) I have followed your procedure and finally I have fixed my Xperia LT15i.
I had deleted services and applications in order to optimize my phone until I reached a point where my USB connection failed. I had no way to reflash it and i felt lost.
This morning I had the plan to get a new phone. Thanks to you I have saved a lot of money!!!

Help. When I try to connect a smart phone (Huawei G510 4.1.1) to the computer, nothing happens, the computer does not have any notice, in My Computer has a new icon. On the phone is switched on only charge the battery, there is no option as they appeared before you connect them via USB. On computer instaled a Hisuite which also does not recognize the phone. On the phone is switched on USB debugging.I tried everything, installed some drivers. Does anyone know what it can be and how to solve it? (Huawei G510-0200,new usb cable,Windows 10 x64)
I have the model with Snapdragon, before I did not have this problem but now I do. I want to install TWRP and root but when I connect it via USB it is connected and disconnected continuously, I have changed cable, PC, I have installed the drivers ... I want to know if there is a solution or at least TWRP without PC. (I have the latest version of MIUI stable)
Do you have another pc or laptop u can try this with and tell me if the problem still persists? Another solution are linux, because in my case my windows 10 pc wouldnt recognise my rn4 mido device, when i used linux it was all fine. Or rollback to a previous Miui like 8 and try connecting it to the pc again.(You can go to the nearest Net cafe and try it btw, just like i did lol)
Hello,
I've just update my Mate 10 to .136 but since this update, i can't connect my phone to my computer by USB MTP like before with .135
When i connect, i can see the hisuite drive.
The only way to transfer file is to install hisuite
I'm on Windows 7. I also try on a Windows 10 and i go to the hidden menu to change setting to google mode, manufactuer mode or hisuite mode but it's the same
It seems windows can't recognize the phone driver. I tried other cable and it's the same (original or other phone cable)
I also tried other phone on my computer and it work.. (lemax2 and alcatel)
Can someone help ?
thanks
Did you try with USB Debugging turned ON in Developer Settings ?
Yes, USB debugging and also HSB
On windows MTP drivers has a "!"
But i dont know why
The drivers worked with other phone and with previous firmware (OTA update)
nobody has the same problem as me ?
