While I'm sure most of you out there who installed OS 10.1.0.2009 onto your BlackBerry Z10, have not even yet settled into it, another leaked OS is now available for download. Like the BlackBerry Q10, this one is sitting at OS 10.1.0.2342 thanks to forums member lbfe and is a full autoloader package for BlackBerry Z10 Models STL100-2, 3 and 4. If you're looking to know what's fixed, updated and still buggy, you'll need to hit the forums in order to comb through the info.
Right then, as always - use caution when installing a leaked OS like this and remember if you break your phone it's not our fault. Also, a good idea to make a backup because you're essentially performing a factory restore on your device. If you don't want to lose data, a backup is needed. You'll need a Windows PC to install these files and If it goes downhill, remember you can always wipe and restore your device.
