Hacking

I reverse engineer stuff and make cameras better.
Choose your camera model to see hacks available:

Camera model	Script type
GoPro HERO3 Black/HERO3+ Black/HERO3+ Silver	Standard A7 scripts
GoPro HERO2/HERO3 White/HERO3 Silver	t gpio A5 scripts
GoPro HERO4 Black/Silver	Not working, experimental
GoPro Hero Session	Standard A7 scripts, beware of limited use
GoPro Hero 2014	Standard scripts
GoPro Hero 5/6	Soon!

How to hack GoPro cameras

You may be thinking, what are these autoexecutables, or why are these codes useful?
GoPro cameras use a Ambarella chip, very often, GoPro refuses to use and include a GUI graphical menu in the firmware some of the resources the chip provides, an example of this: the GoPro HERO3/3+ use A7 chip from ambarella, this chip supports long exposure pictures. I managed to hack the GoPro HERO3/3+ cameras to take long exposure pictures.
These commands are obtained via a firmware reverse engineering research or via linux scripting.
For user's facilities, I made a git repository with autoexecutable hacks for different GoPro camera models, most popular are the long exposure hack for the HERO3/3+ and the MegaLapse hack that allows GoPros to take long intervals for timelapse.
Visit AutoexecHack repo
The commands inside autoexec.ash, the file you put in the SD card for the GoPro to execute on start up is written in Ambarella Shell, ASH. The Ambarella Shell language is based on Linux, as it supports mv, cp and it has lu_util exec, a utility to execute commands in the GoPro's Linux side.
To download, install and execute a GoPro AutoexecHack file:

• Go to the code github page, should display some code
• Locate a RAW button
• If you have a HERO3+/4 camera, insert the SD card in your computer
• If you have a model below the HERO3+, use USB or sd card
• Right click on that RAW button
• Choose "Save As"
• Choose the location of the SD card where the two folders DCIM and MISC are
• Eject USB/sd card
• Power on your GoPro
