Now the First Interop Unlock hack for W10M is now available. It's currently limited to LUMIA/SAMSUNG phones, although we're trying to extend it to other OEM Device, of course. (It requires specific Driver/Services to 'RUN' into 'SYSTEM' Privileges. Hence, other OEM Device is lack of these. I.e HTC/Micromax etc. etc.)
*** UPDATE : Microsoft is trying to break our hack through blocking 'NdtkSvc' on Lumia. So the hack currently doesn't work directly on Lumia 950/550 or later. Even if you updated extras+info on any lumia you will loss Service Access. So Stay Away from Extras+Info***

A brief summary, for those unfamiliar with interop-lock:
Windows Phone allows a number of high-privilege app capabilities, which can be used to make changes to the OS which are normally not possible for a third-party Applications.
The limitation on whether we can use these capabilities or not is based on what 'level' of developer unlock the phone has.
ON WP7/8/8.1
Standard 'ISV' (Independent Software Vendor) Dev Unlock (max 10 apps or less) is what pretty much everybody gets.
OEMs, however, get a special OEM Developer Unlock (300 apps or more) which gives them the ability to use much higher-privilege app capabilities than the standard ISV unlock permits. The name comes from ID_CAP_INTEROPSERVICES, the capability which was most important in WP7/WP8/8.1.
However, there are a great many interesting capabilities. Note that Interop-unlock by itself does not enable all of these. However, at least on Lumia/Samsung phones, it is now possible to enable *all* the capabilities.

My phone's specs are: Nokia Lumia 830, Windows Phone 8.1 Update 2 (version 8.10.15148.160), hardware version 1.0.0.0. Find Unlock- Interop Unlock.
