The remaining Windows Phone community have a lot of thanks due to Rene Lergner a.k.a. Heathcliff74, who created the Windows 10 Mobile unlock solution that finally broke Microsoft’s bootloader protections and who allowed such crazy developments such as full Windows 10 on ARM.
He’s gotten a bit busy however and will not be able to give the project his full attention any more.
Like any good hacker in that position, instead of just disappearing, he has made his project, WPInternals, open source, meaning any good developer can take over his work, to update, modify or bug fix.
Good move – and most likely the only way for the foreseeable future we’ll be able to do any modding of Windows Phone and its devices, considering Microsoft has mostly abandoned the platform.
