## What it is
Unleashed Firmware is an unofficial custom firmware (CFW) for the Flipper Zero multitool device, written in C. It extends the stock firmware with expanded Sub-GHz protocol support, rolling-code programming, extra frequencies, a large plugin ecosystem, BadUSB/BadBT enhancements, and various quality-of-life UI improvements.

## Use cases
- unlock extra Sub-GHz frequencies and protocols on Flipper Zero
- capture and replay rolling-code remotes like KeeLoq
- extend the Flipper Zero infrared universal remote database
- run community plugins and custom apps on Flipper Zero
- use BadUSB scripts over Bluetooth with BadBT
- remove region lock and add external radio modules
- fuzz RFID and iButton protocols for security research

## When to choose
- you own a Flipper Zero and want expanded radio protocol coverage beyond stock firmware
- you need rolling-code remote programming and extra Sub-GHz frequencies
- you want a large maintained plugin/app ecosystem for Flipper Zero
- you do hardware security research on RF protocols, RFID, or NFC

## When to avoid
- you need only officially supported Flipper Zero features and warranty compliance
- you want a firmware for devices other than Flipper Zero
- you are uncomfortable with unofficial firmware that may void device warranty or violate local RF regulations
