Hi,
I am from Mumbai.
I am using Nokia Lumia 925 with Insider Fast Preview.
Currently using 10586.164 i tried for update but not gettting any updates .
Can any one help me what can be the problem.
your device is not upgradable to windows 10 mobile & in order to get the latest build you need to on the fast ring and you are on that but-" only devices that are either upgradeable/upgraded or are shipped with windows 10 mobile could receive the update"
so there is the line drawn, what you could do is switch to slow/release preview build and keep getting future 10586.xxx builds
or
upgrade to a windows 10 running device , i know 925 is a sweet device, letting it go will be tough
