Reboot

We regularly update the firmware by adding new features. These updates improve the performance of the device, but there may be cases where your Flipper Zero becomes unresponsive or freezes after an update. In most cases, a normal reboot will fix the problem. However, in rare cases, you will need to perform a hard reboot or switch your device to Recovery mode for the firmware repair.
You can reboot your Flipper Zero in many ways, such as using hotkeys, in Settings, and through the Flipper Mobile App.
If your Flipper Zero freezes and fails to respond to button presses, reboot it by pressing and holding the %left%LEFT and %back%BACK buttons.
Rebooting your Flipper Zero in Settings can also be helpful when using qFlipper or the Flipper Mobile App screen streaming. The streaming feature enables you to control and reboot the device remotely.
To reboot the device, do the following:
Go to Main Menu -> Settings -> Power -> Reboot.
Select the Flipper OS option and press the %ok%OK button.
To reboot your Flipper Zero via the Flipper Mobile App, do the following:
In the Main Menu tab, tap Options, then tap Reboot Flipper.

If the device still freezes after a normal reboot, try performing a hard reboot by pressing and holding the %back%BACK button for 30 seconds. This type of reboot resets the power circuit of your device.

Occasionally, your Flipper Zero may fail to update correctly, display images, or respond to button presses. These issues could be caused by corruption in the device's firmware. You can repair the corrupted firmware by rebooting your device to Recovery mode and running the qFlipper desktop application.
