SD Flash Files for Solo and Controller

BlackHawk · Sep 19, 2024

I was in the process of bringing my Solo back to life yesterday via SidePilot and made the mistake of pushing the Open Solo 4.0.0 Clean Install to the controller first thus breaking the communication to the Solo itself for the Solo update. I've been following the instructions and have the SD cards out but can seem to find the"Open Solo SD Card Image.7z" referenced here: documentation/install_sdimage.md at master · OpenSolo/documentation

Can anyone point me to the correct Open Solo files that I can flash to the Solo and controller SD so I can fly via SidePilot? Extra points for links to software allowing me to do this on my MacBook.

Thanks in advance!

The following links contain the image files needed to flash Solo SD cards and Cube to Open Solo 4. The images include the Updated Factory Reset Partition files so that a factory reset will result in a fresh install of Open Solo 4. Also included is the Arducopter v4.0.1 APJ file for a Stock Solo Cube.

If you pair them you should be able to update them even if they are mismatched. See my video where I demonstrate it a few times.

Hi, I'm also in the process of trying to restore my 3DR to flight ability and as I can't pair and password is not correct I decided the best way to get back to flying would be to flash an image for the Solo and Controller. I've managed to get the Micro SD cards out but I'm having trouble with the dropbox files. When I try to get into them I get a message: "Can't Load without File Extension". I can't find a file extension for Safari. I'm really hoping that someone out there has usable copies I can get download so I can flash the card. Really appreciate any help you can give me.

Use the files in this link. The instructions for flashing are in the PDF so make sure you follow them. https://www.patreon.com/posts/open-solo-4-96976821

Thank you so much. I was able to download the files and Flash them on to the micro SD cards for both the controller and Solo. I'm hoping to get everything back together tomorrow and do a test flight.

Make sure to flash the Cube with the.apj file.

Sorry to be slow here but how do I flash the Cube? From what I read, I need to run Open Solo Companion on my computer. I have the .apj file I just can't find the Open Solo Companion. Really searching for this I just can't find it.

ps: I just thrilled that the controller and Solo are talking to each other and I can connect through SidePilot.

The step by step instructions are in the pdf file I mentioned above. It is listed right next to the APJ file.
