its updated to latest version, its 22.214.171.124
Nokia X software platform 1.2
I downloaded Nokia X Manager, thanks to Stanley
but it was missing 64bit drivers,
I then installed Nokia X Toolkit, and install driver by pressing 1
still both of the tools weren't detecting my phone.
but by now i have nokia drivers in my windows 8.1
Go to Device Manager -> Right Click Nokia with Question Mark -> Update Driver -> Browse locally... -> Let me choose from installed drivers (b/c downloaded files were getting ignored) -> in the list of installed drivers go to Nokia-> select ADB click next and boom XL detected.
Follow Nokia X Manager and get Google play and other stuff on biggie phone with nice camera.
I bought it for 16500 pkr 2 days ago.
Hope it helps.
