Galaxy S7 won't connect to Windows 10 laptop

[rkidcd911x]

Hi I have the UK version of the Galaxy S7 SM-G930F on the O2 network running Android 6.0.1

Baseband:- G930FXXU1BPJG

Build :- MMB29K.G930FXXS1BPLD

I have tried to connect it to windows 10 using both Smart Switch and Kies 3 and both time my laptop doesn't seem to recognise the handset. When i plug in my Samsung USB cable the handset charges but nothing else happens. I don't even get an error message saying my handset can't be recognised.

I have updated Kies too the latest version and the USB drivers.

Any ides / solutions to my problem?

Thanks

Hi @rkidcd911x. :smileyhappy:

When it's plugged into your laptop pull down the Notification bar on the phone. Is it showing as "Connected as media device" by the USB icon?

I've been having exactly these symptoms. The phone shows the "Cable charging" option but clicking it goes to the Battery details.
I've tried three cables which all work with my tablet (Nvidia SHIELD), and work with my partners S7.
I've tried:
Installing Kies, reinstalling Kies / Drivers
Setting the transfer mode using the Developer tool
Setting the transfer mode using the #*8080# debug menu
Restarting phone
Restarting PC
3 different USB cables
4 different USB port

Also tried Smart Switch, doesn't detect phone either.

Tried everything in that guide short of the factory reset. 😕

I would do the reset anyway and if it keeps doing it try to another pc? just thinking if you rule out software with the reset and rule out the other option by trying it in another PC then it would be something Samsung would look at under the warranty.  *just remember to back up what you can to SD card*

You will need to contact O2 for a PUK code ether over the phone or online here http://www.o2.co.uk/puk/landing/ Iet me know how it goes

I wrote to O2 and I went to the office today but they don't have an idea how to fix the device.We've entered many codes but they don't work.I have PUK1 and PUK2 for my Three SIM card but they don't work.I don't know which Sim network PUK I need to enter to unblock  it.
