Why would anyone build with this?

REASON 1

Replay captured wireless signals from garage doors, gates, and other Sub-GHz devices using your Flipper Zero.

REASON 2

Control home electronics like air conditioners, projectors, and fans using expanded universal infrared remotes.

REASON 3

Read and parse additional transit and access card types not supported by the official Flipper Zero firmware.

REASON 4

Use the BadKB feature to make your Flipper Zero act as a Bluetooth keyboard for automating computer tasks.

How do you spin it up?

Difficulty · moderate Time to first run · 30min

Requires owning a Flipper Zero device and flashing custom firmware onto it using a USB connection and the qFlipper desktop app.

The explanation does not specify the exact license, but states the firmware is entirely free and open-source with no paid versions.

Wtf does this do

Unleashed Firmware is custom software for the Flipper Zero, a small handheld device often described as a "multi-tool for geeks" that can interact with wireless signals, infrared remotes, NFC/RFID cards, and more. This firmware replaces the official software that ships with the device, adding extra features and capabilities while keeping compatibility with existing apps. The biggest changes are in how the device handles Sub-GHz radio signals. This firmware adds support for many additional wireless protocols and frequencies, lets you save and replay captured signals (including some rolling code systems used in garage doors and gates), and supports external radio modules for better range. It also expands the infrared features with universal remotes for more device types like projectors, fans, and air conditioners. On the NFC and RFID side, it adds the ability to read and parse many additional card types, including various transit and access cards from around the world. Beyond signal handling, the firmware includes quality-of-life improvements like a customizable device name, a desktop clock, different battery display styles, and a PIN lock. It also bundles community-made plugins and games, plus tools like a Sub-GHz brute-forcer for static codes and a remote control app that can trigger saved signals from buttons. Some features, like BadKB, let the device act as a Bluetooth keyboard for automation tasks. This firmware is aimed at Flipper Zero owners who want to push the device beyond what the official software allows, hobbyists, security researchers, and tinkerers exploring how wireless protocols work. The project emphasizes that it's for experimental and educational use, not illegal activities. It's developed by a small volunteer team and is entirely free and open-source, with no paid or premium versions.

Yoink these prompts

Prompt 1

Help me flash Unleashed Firmware onto my Flipper Zero. I have a USB cable and the qFlipper app, what are the exact steps to install the custom firmware?

Prompt 2

I installed Unleashed Firmware on my Flipper Zero. How do I capture and save a Sub-GHz signal from my garage door remote so I can replay it later?

Prompt 3

I want to use the BadKB feature in Unleashed Firmware to automate typing a script on my computer via Bluetooth. How do I set that up and create a payload?

Prompt 4

Walk me through reading a transit card on my Flipper Zero running Unleashed Firmware. Which NFC app should I use and how do I parse the card data?

Prompt 5

How do I connect an external CC1101 radio module to my Flipper Zero running Unleashed Firmware to boost Sub-GHz signal range, and where do I configure it in the menus?
