After a very long and a much shorter delay, the long-awaited jailbreaking solution for Windows 10 Mobile by Rene (Heathcliff74 ) is now available.
The application supports all Lumia handsets (but not from other OEMs) but of course, comes with no warranty.
In theory, it can be used to install Android ROMs on Windows 10 Mobile handsets, but this is not a specific application Rene will be supporting. He is, however, looking at porting Project Astoria back to current builds of Windows 10 Mobile, and will presumably be working on that from his site.
See his announcement video for more information below.
