Shut down the BlackBerry Link program (and BlackBerry Desktop Software if installed).
Unplug the phone from your computer.
On your computer, go to www.blackberry.com/updates. Scroll down the page and click the Check for Updates button.
Connect the BlackBerry Z10 smartphone you're having problems with.
Hold down the power button on the phone for 10 seconds until it turns off, then press the power button again until it turns back on. A prompt will flash up on the PC and the BlackBerry smartphone will appear in the drop-down list. If at this point the phone will not switch on and the LED blinks twice and powers off, please see below.
Click the OK button when you see it (you only have 15 seconds to do this). you'll see a message saying 'Checking for BlackBerry Device Software updates'.
The phone will turn itself off and you'll be prompted to install BlackBerry Device Software. Follow the prompts and when it's done the phone should be recovered.
If the LED blinks twice and the phone won't switch on this usually means there's no operating system on the device and it needs reinstalling.
Open the Blackberry Link software on your PC and plug the device in.
In the Blackberry Link software click Preferences in the top right hand corner and select Reload Device Software.
Select Reload and the software will ask you to press the power button for 10 seconds.
It should then detect the device and start to download the operating system.
Leave the device to update and, if all goes well, it should reboot and be ready to setup.
