My Lumia 925 is not connecting or discovering any devices...I've checked the usual checklist soft reset and hard reset included which leads me to the conclusion of a faulty Bluetooth module or flex (don't know the difference or what is the right term). Problem is Bluetooth replacement parts for 925 are hella scarce and don't ship to Nigeria. So I was wondering if Lumia 930's Bluetooth flex is compatible with Lumia 925
Also side note, if your Lumia 925 is not 4G compliant, can changing the antenna change that or is that a feature that is region or hardware dependant?

if your Lumia 925 is not 4G compliant

If your phone is still running on Windows Phone 8.1 then Microsoft had long ago released an update to that phone which had enabled 4G & you could select it in network options.

It is RM910 so I don't think so

But do you think the whole 925 RM892 and RM893 having 4G and RM910 the one I use not having is hardware dependent or is it software. And if I were to flash the firmware for one of these two would I have 4G? Has it been done before?

Really?!! I never knew about this. I thought they had updated all 925's and made them 4G enabled. I know don't anything about the firmware hack.
