Reboot



The Flipper Zero firmware is updated regularly. We work to ensure that the device runs smoothly. In rare cases, users encounter hang-ups and bugs while working with Flipper Zero. This is normal. To restore the operation of the device, perform a reboot.



Normal reboot

The key combination :left:LEFT + :back:BACK hardware restarts the processor and performs a normal reboot. Even when the operating system does not respond, the hardware restart will still work.




Recovery mode (DFU)

In this mode, Flipper Zero activates the bootloader and is detected in the computer as a DFU device. When the firmware is updated, Flipper Zero enters the recovery mode on its own. To exit this mode, perform a reboot.



To reboot to the DFU mode:

  1. Press :left:LEFT + :back:BACK at the same time like a normal reboot.
  2. Release :back:BACK but don't release :left:LEFT until the blue led lights up.
  3. You will see a message on the screen that DFU mode is on.
  4. Rebuild firmware according to instructions: Firmware recovery.



Full recovery mode

If the bootloader is damaged, rebooting to update mode will not work. There will be no image on Flipper Zero's screen and the status LED will not work. In this case, only the full recovery mode will help to restore the device.

To activate full recovery mode:

  1. Disconnect Flipper Zero from the USB.
  2. Press and hold the :ok:OK + :back:BACK button for 30 seconds.
  3. Connect the device to your computer.
  4. Restore the firmware according to the instructions: Firmware recovery.




Reboot from the Main Menu

You can restart your Flipper Zero from the Main Menu, which can be useful when working through qFlipper. To restart your Flipper Zero from the Main Menu, do the following:

  1. Go to Main Menu → Settings → Power → Reboot.
  2. Select Flipper OS, and then press the :ok:OK button.



Reboot from the console

Flipper Zero can be rebooted via Command Line Interface.

To perform a reboot via the console, do the following:

  1. Connect your Flipper Zero to your PC.
  2. Open Putty.
  3. Connect to the Flipper Zero COM port at 115200 bauds.
  4. Enter the reboot command and press Enter.

After the reboot, the message about loss of connection will appear.
