Unleashing The Power Of the Flipper Zero

Welcome to my blog! Today we're going to unleashing the power of the Flipper Zero by installing some custom firmware. But before we get started, let's make sure your Flipper Zero is running the latest version. if not download latest version from here.

Updating Flipper Zero:

After downloading the Flipper Zero desktop software, open it from the icon on your computer. Then, connect your Flipper Zero to your computer using the USB C cable that came with it. The software should automatically detect the firmware version on your device. If it's up to date, you can move on to the next step. But if it's not, go ahead and click the 'install' button to update your firmware.

Backing Up Flipper Zero:

Before moving on, it's a good idea to back up your device. This is simple to do - just click on the spanner menu button. From there, you'll see a number of options, including 'backup', 'restore', 'erase', and 'check for updates'. To create a backup, just click on the 'backup' button and save the file it generates to a secure location.

The Flipper blog suggests that updating the firmware on the Flipper device is typically a reliable process. However, as with any firmware update, it's important to be cautious and avoid interrupting the process, as this can potentially damage the device. The Flipper device appears to have a fail-safe in place that keeps the old firmware intact until the new firmware is successfully installed.

Finding Custom Firmware:

Now that you've updated your Flipper device and backed up your data, you may want to explore custom firmware options. One option is the unleashed firmware by Eng1n33r. which is known for its ease of installation and additional features. These features include community applications for tasks like fuzzing, as well as some games like Doom. Overall, the unleashed firmware offers a range of enhanced functionality for your Flipper device.

Downloading Custom Firmware:

To download the custom unleashed firmware flipper, go to the releases page on GitHub. You should see a link to a .tgz file. Click this link and save the file to a safe location on your computer. Note that there is a web installer that can make the installation process easier, but I found it didn't work for me. You will need to use a Chromium-based browser, but it may not work if you have an older firmware version installed.

Installing Flipper Zero Custom Firmware:

To install the custom unleashed firmware of Flipper Zero, go to the settings page in the Flipper Desktop application. There, you should see an option to install the firmware from a file. Click this option and navigate to the .tgz file that you downloaded. The desktop application will then show a progress bar while it installs the firmware. Once it is finished, the custom firmware should be installed and ready to use.

After the Flipper desktop application reaches 100%, you will need to follow the instructions on your Flipper Zero device to complete the installation. This may involve pressing buttons or making other interactions with the device. After a few minutes, you should get a notification that the Unleashed firmware has been installed successfully. This notification should look similar to the image you provided. You can then start using the custom firmware on your Flipper Zero device.

Unleashed Firmware Features:

The custom firmware, called Unleashed, comes with a number of new features and apps. It includes games like Doom, Tetris, and Flappy Bird, which you can play in between your hacking activities. You can find a full list of features on the firmware's webpage. I may write a separate post or create a video about these features in the future. For now, you can try them out on your Flipper Zero device and see how they enhance your experience.


This post is not intended to be a comprehensive guide to the features of the Unleashed firmware. Instead, it focuses on how to find and install the custom firmware safely. The developer provides detailed instructions on their GitHub page, so this post may be redundant. However, I wanted to provide an additional resource for those who are interested in installing the firmware. In my personal experience, the Unleashed firmware adds useful functionality to the Flipper Zero device. However, I plan to switch to the Roguemaster firmware in the near future.
