Hello!
How do I reset my Cerbo GX to factory settings/firmware?
I am considering playing with it over SSH but want to know I have a way to revert whatever mess I might create.
Thanks!

Cerbo GX Factory Reset
Hi Eran, just now I added an answer to your question to the root access document, here: https://www.victronenergy.com/live/ccgx:root_access.
see the warning section. Thats what I expanded.
UPDATE 2023: see also here https://community.victronenergy.com/questions/204255/cerbo-gx-bricked-how-to-recover.html
An added note: the factory reset procedure does not reinstall the operating system so if you are suffering from a "white screen" on the GUI or other not-functional parts of the system due to operating files being changed/corrupted, resetting the /data partition will NOT recover the system.
In addition, performing the factory reset will most likely remove ssh access so you will no longer be able to access the command line remotely.
A better approach to recovering a non-functional system (assuming you can get ssh access) is to force a firmware update.
For on-line updates:
/opt/victronenergy/swupdate-scripts/check-swupdate.sh -force -update
For updates from removable media:
/opt/victronenergy/swupdate-scripts/check-swupdate.sh -force -update -offline
@Kevin Windrem will the update from removable media work from the onboard serial connection if there is no access to ssh?
And what if it is in this state ?

Hi,
This document point to what looks like an outdated Link. Specifically I am looking for instructions on How to do a Factory reset of the Cerbo GX.
The document listed here suggest that there will be a later addition to manual and offers a Link to github. the GitHub link appear to be a dead link.
For a factory reset of the Cerbo GX please see the Reset to factory defaults procedure in the manual.
Hi Stefanie,
Thanks for the tip. But not sure at this point I can change the Username.
Both CCGX and CerboGx documention point to a file with the exact same name. Are they effectivley the same or should we keep them in separate folders?
Yes, they are effectively the same file as Venus OS is the same on all GX devices.
Hey @Kevin Windrem I have serial console access to the old bricked cerbo. When I reboot I can see a lot of activity going on loading things so something is happening, but unfortunately I have discovered that the /opt directory is empty. Is this recoverable or is it hosed?
It's pretty well bricked. /opt is where all the Victron code is located including the firmware update shell scripts.
I really don't know Linux very well but would it be possible to copy the /opt directory from a working cerbo onto the bricked one through the console? I'm assuming that the file structures and read/write permissions would be an issue?
I originally decided on the cerbo because of the plug and play simplicity of all the components. If I'd known what I know now I might have decided to go with the raspi
Well I just answered my own question. I copied the scripts from a working system, set file permissions, and ran the script to boot from the other image. Cerbo is back. I surprised myself.
