There are a few possible causes of this error:

*** The USB connection is not stable.** Make sure that the Flipper Zero is securely connected to your computer. Try using a different USB cable or port.

*** The Flipper Zero’s battery is low.** Make sure that the Flipper Zero is charged before trying to install the firmware.

  • There is a problem with the firmware file. Try downloading the firmware file again from the Flipper Zero website.

There is a problem with the Flipper Zero itself. If you have tried all of the above troubleshooting steps and are still getting the error, it is possible that there is a problem with the Flipper Zero itself. You can contact Flipper Zero support for help.

Here are some additional tips for troubleshooting this error:

  • Check the Flipper Zero logs for more information about the error. You can open the logs by clicking the “LOGS” button in the Flipper Zero app.

  • Try installing the firmware using a different computer.

  • Try flashing the Flipper Zero with a different firmware image, such as the STABLE firmware.
