A few days ago, we wrote about the interop unlock achieved by XDA Recognized Developer GoodDayToDie on his Samsung Ativ S running Windows Phone 8. At the time, however, there was no guide / procedures thread for users to follow in GoodDayToDie’s footsteps. However, good things come to those who wait, as the product of GoodDayToDie’s and Senior Member -W_O_L_F-‘s work is now clearly described.
If you’re new to Windows Phone, you may be wondering what exactly you can do with interop-unlock. According to GoodDayToDie:
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 app. The limitation on whether we can use these capabilities or not is based on what “level” of developer unlock the phone has; 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. In WP8, however, there are a great many interesting capabilities. Note that Interop-unlock by itself does not enable all of these; a deeper unlock is still required to fully “root” the OS.
Since our last update, GoodDayToDie has now created the thread and filled it with the requisite information including a brief primer on what interop-unlocking your device accomplishes, as well as a simple guide showing how to achieve interop-unlocked status and what capabilities are gained.
Just as before, this is just for Samsung Windows Phone 8 devices, as it relies on the Samsung diagnosis app. However, work is in progress to extend this to other phones.
Head over to the guide thread to get started._________
