Here’s a quick overview of three different ways you can reset your device and when to use each option.
I’ve also included some tips to help you start PRIV if your device is showing a black bootloader screen, or a black screen with the Android robot on its side, and an orange/red explanation mark above it.
Let’s begin 
The first method, which should be used 99.9% of the time when you want to reboot your device, is using the Reboot option that appears after pressing the Power key.As mentioned earlier, PRIV offers three different reset methods.
- Press and hold the Power key for 3 seconds
- Select Reboot from the menu that is presented
The second reset method should be used if pressing the Power key does not produce the menu with Power Off and Restart. For example, if an app or game you are using won’t close, use this option to restart your device.
- Press and hold the Power key for 12 seconds
Should your device fail to respond, the final reset method is to press and hold the Power key for 32 seconds which is equivalent to removing the battery. This should result in your device booting up successfully.
If it fails to start, however, verify you are not pressing any other keys such as Volume Up, Mute, or Volume Down while performing any of the reset methods listed above. If you use a case for your device you may want to remove it as it might be pressing a button inadvertently.
Should your device fail to start after completing these reset methods, review the following and, should the issue persist, please call BlackBerry for assistance.
Screen is black, and PRIV doesn’t show any LED activity
In this scenario, connect your PRIV to the charger that came in the box and plug it in. When your device shows the battery icon with at least 5% charge, press the Power key, ensuring no other keys are pressed for 3 to 5 seconds to start your device. Should PRIV fail to start up, please contact BlackBerry Support.

If you find your device in this state, press and hold the Power key for 15 seconds, ensuring the Volume up, Mute, and Volume down buttons are not pressed. Should PRIV fail to start up, please contact BlackBerry Support.
