We have been seeing some leaked install files in the past for the BlackBerry Z10 STL100-2 model. This is the international version of the Z10 which thanks to this leaked OS got up to the 10.0.10.822 that AT&T released for the STL100-3. Kudos to RapidBerry for scoring the install for us. Keep in mind this install can brick your device and wipe all your data so we take no responsibility for anything you do!
