I used WPinternals 2.8 on all my devices up to about 2 years ago. I know of maybe another version 2.9? The developer moved on to other projects. 2.8 will work, and before you unlock a boot loader or go flashing stuff just make sure you read as much as you can in WPinternals in the app all sections, when you read a term or see something you do not quite understand look it up and read more before you commit to anything. Otherwise if you just want to experiment and don't care about the device as much check a couple threads where someone uses this tool to flash a custom firmware or to load a custom app or two. These tools really imo were development tools because W10M had huge potential but since Microsoft thought otherwise, it tools like this and many other projects and discoveries never unfolded. So really you would be using that phone and Windows Phone internals for your own edification and or enjoyment more than anything else.
Have tried this just yesterday but it does not work on my windows 10 pcHave you try this?
I really sorry if there are another tutorials about this, but I wanna shared this easy method to deploy any xap you want, especially root and interop unlock tools. NOTE: This tutorial is oriented to people with low-requeriment PCs like x86 SO or...forum.xda-developers.com
