Windows Phone Internals is a tool for users of mobile phones with Windows Phone 8.1 and Windows 10 Mobile. It is used to unlock the bootloader, get root privileges, and even allows you to upload both your own and community built ROMs. Using an application developed by the well-known hacker of the XDA Developers community, we will not only be able to install our own software on our Lummies (and in the future not only Lummies), but also allow applications to leave their sandboxes, back up software images on the phone and access the device's file system in mass storage mode.

The package also includes an SDK, thanks to which copyrighted applications for Windows Phone can easily access the file system and registry. Note: the unblocking of the smartphone may be considered by the seller as a pretext to terminate the warranty agreement, although the legal situation is not clear.
