I have installed windows 8.1 pro N final which has been activated by phone. I thought there was no significant differences between pro N and pro except windows media player. But my computer cannot recognize my Lumia 520 phone as a portable devices or something like that. In devices manager, there was a yellow triangle with an (!) on RM-914 Lumia 520 ( my phone) line. Anyone has a solution to solve that problem ?
Neither ways works. I reckon that the problem relies on drivers. I mean windows pro N lack driver for my phone, and it cannot browse internet to look for it
If it really depends on being N or non-N, just install the media feature pack and you'll be good to go. However, I'd be surprised if really that was the problem.
I had the same problem with an iPad on Windows 8.1 Enterprise N. iTunes installed ok and I could access my device through it, but it did not appear in the list of removable devices in file explorer and I could not access the pictures I took. I had a yellow exclamation point in device manager next to my iPad device, just like you. I also had a problem reading youtube videos; after an update to the flash componenent, internet explorer started crashing when reading videos encoded in h.264. Old flash animations worked fine. All problems solved when I switched to Windows 8.1 Enterprise (I had this option through my MSDN subsciption), even with multimedia components removed after installation. There seems to be a lot of little things missing in "N" editions, in addition to the multimedia parts of the OS. I don't know if installing the media feature pack on an "N" edition would also install these missings parts, cause I didn't try it, but that would be an interesting thing to test. I think I'll try it in a VM.
Iaqk, i encountered the same problem with you on my iPhone. I got the problem solved without reinstall the windows. I simply add the Media Feature pack to my Windows 8.1 Pro N. It does the tricks after restart Google for [h=1]Media Feature Pack for N and KN versions of Windows 8.1[/h]
