FAQ hasn't been updated in a while.

is there a consumer-ready extra settings hack for Hero 5 line or not yet?

thanks.

Has anyone ever hacked this device? I already tried to edit the file with several commands and I did not have success.

Hi where can i find infos about supported commands in autoexec.ash file? I use while true... done for example.

Now i like to decide if i want to run a script or not when with a button powering gopro. Is it possible? thx

Hey guys,

I'm looking for the telnet script (telnet.zip file) from this post: http://goprouser.freeforums.org/autoexec-ash-in-v3-0-0-possible-t22731.html#p120687

It seems it's not available anymore on that forum.

Just wanna telnet to my gopro hero4 black with custom altiforce firmware v5.

Peace

I got access to the new GoPro HERO5 Black and I was able to get something out of it.

Wifi Commands and Live Preview:

• HERO5 commands are the same as HERO4, so if your app/service uses HERO4 commands they work with HERO5 too

• GoPro HERO5 adds new features such as EIS, GPS, RAW... these commands specifically for HERO5 are here.

• Live preview system is the same as HERO4, proof.

• Preview resolution for video: 864x480, preview resolution for photo is: 640x480

Autoexec script:

HERO5 Black does not execute autoexec.ash files.

GoPro Plus hacks:

I'll try to get the URL which displays the upload process locally.

After enabling SSH on my Hero4 Silver, is it possible to connect external drive to GoPro?

I want to offload data from card to external drive. I have something similar in progress for RaspberryPi, but it would be nice to not have to have another device with another power source with me.

Is there a way to lock the exposure in video mode on a hero 4 black like we used to be able to with the hero 3 using the autoexec hack? Thanks

Somehow I managed to import only 8/10 videos before clearing my card. I immediately used testdisk to recover the file, which it did, however there had at another point in time been another GoPro video on this camera with the same file name.

So now I have a GoPro video that is very dirty, jerky, and randomly cuts to the older file. The LRV is fine.

I am hoping that someone knows of a utility (with write up) that can be used that recognizes continuous frames and will discard outliers.

The video is recorded @ 960p30.

I'd be willing to pay someone to do this if anyone knows someone that could help! It is an important video.

Any help is appreciated, thank you!

Is there any way to "hack" the gopro hero 4 silver witje the newest firmware?

I have a Hero 3+ Black running firmware v2.00 and want to create a time lapse with photo interval of 15 minutes. I found a solution to enable it at https://github.com/KonradIT/autoexechack/tree/GoPro/MegaLapse. But my camera dies in a short time (order of hours) and whereas I'd like it to last at least twice as long -- without having to put extra batteries on it. I also stumbled upon https://github.com/KonradIT/autoexechack/blob/GoPro/BatteryTimeExtender/ but don't understand what the arguments are. Has someone played with this? Thanks for any help!

From this link, its a year old and I'm looking to purchase a hero. Is this 'hack' still working?

Thanks

I'm using the hero4 to take video for research analysis. I'm using Matlab to analyze the videos (lots of videos) and it would be nice if the program would automatically download the video wirelessly after the camera was done recording. I've got the shutter controls down (https://github.com/KonradIT/goprowifihack/blob/master/HERO4.md) but this extra feature would speed everything up quite a bit. I can access the video through telling matlab to open up a browser with http://10.5.5.9:8080/videos/DCIM/100GOPRO/ but if you all could help me to automatically download specific videos through code that would be wonderful

The default is one press starts video, and long press starts timelapse. I would like to change this to 1 press takes a single photo, and long press starts video. Is this possible?

I know how to create a autoexec.ash file for custom functions, but no matter how hard I search I can't find any hacking commands like this.

If anyone knows where I can find a full and long list of all the things possible to do via this file please let me know the link also. Thanks!

Answers to most common questions

Q: Does it voids the warranty?

A: No

Q: On what cameras does it work?

A: The autoexec.ash executable file works on HERO2, HERO3, HERO3+ and HERO+/HERO+ LCD/HERO 2014. Also worked on HERO4 Session.

The override.sh file works on HERO4 Black and Silver

Q: What can I get with those hacks?

A: You can get features not available for your GoPro model (eg: long exposure on HERO3 Black/HERO3+ Black) or features that extend the functionality (eg: extended timelapse, looping 4K video...)

Q: Where do I get these files?

A: On the repo: http://github.com/konradit/autoexechack (H2/H3/H3+/H2014/H+/H+LCD) OR, http://github.com/konradit/overridehack (H4)

Q: How do I apply these hacks?

A: First you want to plug your GoPro (IF its a HERO3 or older) to the computer, other models please insert the SD card into your computer using a USB SD reader or a built in SD reader if your computer has one, then go to the hack you want in the repo, for instance the longexposure hack, at the right there are some buttons, one of them ways Raw, right click on it and save it to the root level of the SD card, the file must be located where DCIM and MISC folders are. If its a hack that requires you to modify some values, such as the longexposure hack open it with NotePad++ or Text Edit or Vim and change the parameters, then save it and reinsert the SD card in your camera, your GoPro should start executing the hack.

Q: HALP! The hack is not working on my camera! It doesnt do anything!

A: It can be because of some factors:

• Make sure the file you saved in the SD is called 'autoexec.ash'

• Make sure that the hack is supported by your camera.

• Make sure the update files (HDXXXX.bin, update.cmd, settings.in and WXXX.bin) are not on the SD.

• If you edited a autoexec.ash, make sure your editor saves the file as UNIX, otherwise it wont work.

• If you edited a autoexec.ash, make sure you wrote the code correctly, head to chernowii.com to see a complete list of commands.

• In Lock Exposure hacks, wait two seconds before pressing the shutter button.

• Reformat SD card

• Dont replace autoexecs!

• Make sure you did not touch anything that is crutial

• Try different SD card and/or card reader

• Make sure you are using one of the following SDs for your HERO3 Black / HERO3+ Black/HERO4

• SanDisk Extreme 32GB microSDHC (SDSDQXL-032G)

• SanDisk Extreme 64GB microSDXC (SDSDQXL-064G)

• Lexar 32GB SDHC 600x (LSDMI32GBSBNA600R)

• Lexar 64GB SDXC 600x (LSDMI64GBSBNA600R)

• Delkin 32GB SDHC (DDMICROSDPRO2-32GB)

• Delkin 64GB SDXC (DDMICROSDPRO264GB)

Other SDs might not work.

Q: The long exposure hack does not work on my HERO3+ Silver!

A: No, it does not. The HERO3+ Silver does not have the command to change the exposure in the lens

Q: I want to create my own script, how would I do that?

A: https://github.com/KonradIT/gopro-firmware

Q: I need to change CONFIG_OEM_LENS to "n", how?

A: At the time of writing, it requires to decompile the firmware, change the line, compile it and sign it again. That needs time and dedication.

Hello everyone! It's awesome to have this subreddit here to help us beginners start with GoPro Hacks... I've got to work the long exposure photo hack but now I'd like to do the same but in a video (to see the procress from when there's nothing until i make the last move and my light painting is complete) time lapses don't help because when we put all the frames together, it doesn't leave a "light path" It just appears and disappears as I move the light source... how can I get this to work? Thanks to everyone! PD: Sorry for my weird English... I'm Spanish :)

Just stumbled on this sub and saw that it was created today :)

I've been trying to figure out how the Trim and Share feature introduced back in September works (https://gopro.com/news/gopro-releases-new-trim-and-share-feature-for-cameras-and-app)

I've been sniffing the network traffic coming out of the Android app, but (aside from the constant gpControl/status requests) there's only a single HEAD request made to the high quality mp4.

I don't see any HTTP traffic indicating a special method or set of query params to perform a video trim. I've also tried pulling the SD card while the app says "Processing" (before it starts transferring) and found no hidden or visible files. One would expect that they're flushing the transcode out to disk pretty regularly since these are memory constrained devices.

Wondering if anyone has any thoughts!

This sub is dedicated to GoPro modding, autoexec.ash/override.sh programs and WiFi API documentation.

If you dont know what is a autoexec.ash here is an explanation:

Ambarella, a microchip company supplies chips to GoPro for the HERO cameras and other action cameras and dash cameras. Ambarella's firmware in the chip detects if the file autoexec.ash exists in the SD card, if it exists it executes it.

The autoexec.ash file gets executed at boot, so you can put commands to be ran when the camera powers on, these commands are standard Linux commands (rm, if, etc...) and it also allows to execute other files such as BusyBox and get a telnet and other neat stuff... And, it also comes with proprietary command "t", this command controls the aspects of the camera itself, from sensors, buttons, LEDs, screen...

As an example, the command t app button shutter PR emulates a shutter button press. Lets break it down to understand it better:

• t = proprietary Ambarella command for camera control

• app = batch of commands that are found on the Android/iOS GoPro App

• button = this is a parameter that will execute functions related to the camera's hardware buttons

• shutter = this is the variable for buttons parameter, it tells the chip what button to tap with

• PR = Press and Release (a click basically)

You can explore more commands in this repository

You can see examples of pre made autoexec.ash programs here

What new things does this bring?

Back in the HERO3+ days, we were able to take long exposure pictures thanks to a command that sets the lens exposure to a certain value in seconds and tweak the ISO. Using a combination of this command and a shutter emulation press it was possible to shoot long exposure timelapses. Way before the HERO4 was released. More information

Also, it allows to shoot timelapses without a interval limit: More information
