If the last OS leak didn’t work for you check out the latest leak for the Z10 model STL100-2 & 3. The latest leak lbfe over at CB Forums is version 10.1.0.1880 a bit higher than what is being released officially. LBFE says the battery life is much better on this one. I have not installed it yet and hopefully it is true as I am having the worst battery drained after loading BBM Channels. Will install and report back to you later. If you have it install let us know how it compared to previous leaks.
Install at your own risk, we are not responsible if you brick your device in the process. Below are some instructions on how to install the leaked OS.
Installation Instructions if needed:
Turn off your BlackBerry Z10.
Run the file that you just extracted.
Connect your Z10 to your usb cable and quickly turn it on.
The autloader should connect to your Z10 and start the process.
Sit back, have a coffee or a tea and wait until the process is finished.
When the autoloader has written 100%, the program will terminate and the window will close.
Disconnect your BlackBerry Z10 and wait for it to reboot.
Your BlackBerry Z10 will now be in the position that it was in when you purchased it, so set it up as you normally would.
