BlackBerry released a developer beta OS by way of version 10.3.1.2072 yesterday.
As is typical, the beta OS was repackaged with working device radio files to make it available to non-developers.
Apparently, not too many changes have been made, as it closely resembles OS 10.3.1.1949.
Nevertheless, below are the available autloaders if you’re keen to try out this new OS:
Passport – MEGA
STL100-2-3-4 – MEGA
STL100-1 – MEGA
Q10 and Q5 – Mail.ru
Z30 and Classic – MEGA
