How can i backup the original factory installed firmware (2612154) of a Multiplus 24/3000/70-16 before i do the update with the latest firmware (2612433).
I want to do this because if i have problems with newer firmware i could go back to the factory/default firmware.
I see no way of doing this with VEC3(updated) and VEflash seems only to update new firmware.
The oldest firmware i see in the firmwaretabel at https://professional.victronenergy.com/downloads/firmware is 2612159
