> ⚠ **BEFORE BUYING YOURS:** ⚠ Beware of hardware mods that use a custom firmware, which are [NOT COMPATIBLE](https://github.com/eried/portapack-mayhem/issues/264) with older forks, and they do not follow the license. **ASK THE SELLER if the unit works with an specific firmware, for example, pointing to the [](https://github.com/eried/portapack-mayhem/releases/latest) on this repository**
This is a fork of the [Havoc](https://github.com/furrtek/portapack-havoc/) firmware, which itself was a fork of the [PortaPack](https://github.com/sharebrained/portapack-hackrf) firmware, an add-on for the [HackRF](http://greatscottgadgets.com/hackrf/). A fork is a derivate, in this case one that has extra features and fixes when compared to the older versions.
*[PortaPack H2+HackRF+battery](https://s.click.aliexpress.com/e/_dZ7lA96) (clone) with a custom [3d printed case](https://github.com/eried/portapack-mayhem/wiki/H2-Enclosure)*
If you are new to *HackRF+PortaPack+Mayhem*, there is an awesome introductory video by [Tech Minds](https://www.youtube.com/channel/UC9a8Z6Sp6eb2s3O79pX5Zvg) available:
This repository expands upon the previous work by many people and aims to constantly add new features, bugfixes and generate documentation to make further development easier. [Collaboration](https://github.com/eried/portapack-mayhem/wiki/How-to-collaborate) is always welcomed and appreciated.
Yes, both devices are the [same](https://github.com/eried/portapack-mayhem/wiki/First-steps). The one I am using to test all changes is this [PortaPack H2+HackRF+battery](https://s.click.aliexpress.com/e/_dZ7lA96), which is a kit that includes everything you need. Sadly, the people making the H2 never made the updated schematics available, which is not ideal (and goes against the terms of the license). Most members of the community are using a clone of the [PortaPack H1+HackRF+metal case](https://s.click.aliexpress.com/e/_dS6liw4), which does not include any battery functionality, but it is a cheaper alternative.
To support the people behind the hardware, please buy a genuine [HackRF](https://greatscottgadgets.com/hackrf/) and [PortaPack](https://store.sharebrained.com/products/portapack-for-hackrf-one-kit).
The current stable release is on the [](https://github.com/eried/portapack-mayhem/releases/latest) page. Follow the instructions you can find in the release description. There is also [nightly builds](https://github.com/eried/portapack-mayhem/releases/tag/nightly) generated periodically, which include the latest commits, but they may contain incomplete or buggy functionality.
There is a lot of confusion of which is the latest version because no old version used any actual "version number". Additionally, since the files were distributed on facebook groups, github issue links and similar temporal sources, then there was no central location for them.
This fork (**Mayhem**) uses *major.minor.release* [semantic versioning](https://en.wikipedia.org/wiki/Software_versioning), so you can always compare your current version with the latest from [Releases](https://github.com/eried/portapack-mayhem/releases/latest).
* jamesshao8: He keeps his own version of the fork, while not attached as a fork to anything. Latest functions do not follow the license and are not being published with source code, so keep this in mind
You can write [documentation](https://github.com/eried/portapack-mayhem/wiki), fix bugs and [answer issues](https://github.com/eried/portapack-mayhem/issues) or add new functionality. Please check the following [guide](https://github.com/eried/portapack-mayhem/wiki/How-to-collaborate) with details.
Consider that the hardware and firmware has been created and maintain by a [lot](https://github.com/mossmann/hackrf/graphs/contributors) of [people](https://github.com/eried/portapack-mayhem/graphs/contributors), so always try colaborating your time and effort first.
