Firmware updating

This website is designed to assist you in updating the firmware of your ESP32 Dev Boards for the Flipper Zero. To utilize this web tool, follow these steps:

  • You might need to install the driver from Silicon Labs in order for the ESP32 to be recognized.
  • If you are getting a connection or sync error try to reboot or power cycle the dev board and refresh the web-page.
  • You have to install the Flipper Zero WiFi Marauder companion app in order to use this firmware. (https://lab.flipper.net/apps/esp32_wifi_marauder)

Some custom flipper firmware like Xtreme, RogueMaster, Momentum are custom and may require for you to use there tools, flasher, and software in order to work.

FzeeFlasher and its affiliated entities disclaim any liability for damages, misuse, or unintended consequences resulting from the use of this firmware tool or the flashing of firmware onto your device.
