Looks like BlackBerry Z10 users have the option to install OS 10.1.0.1429 for their STL100-2, STL100-3, STL100-4 devices, which is the full OS leak, not the stripped version which is mainly for developers.

BlackBerry Z10
Click on the link below to download the OS leak for your Z10 device;
- BlackBerry Z10 Smartphone STL100–2
- BlackBerry Z10 Smartphone STL100–3
- BlackBerry Z10 Smartphone STL100–4
Note: download & install knowing fully well that this is only an OS leak, and as such, may cause your BlackBerry Z10 device irregular behavior , up to and including bricked.
Please post below in the comment box if you would like to provide users anything they may need to know beforehand installing this OS leak, it would be appreciated.
As usual, always backup your BlackBerry Z10 device using the latest BlackBerry Link 1.1.0.33 (Windows OS) or BlackBerry Link 1.1.0.28 (Mac OS) prior to any (Official or Leak) OS install.
Sincerely,

Have You tried to install it on DevAlpha?
I have never tried to install this OS leak on a BlackBerry Dev Alpha device, only for BB10 Z10 as my WordPress blog suggests.
I have tested .1627 and .1720 on my friend’s Z10 which I have yet to blog about though:)
