We've got a 3 year old MultiPlus on our boat, which was installed by rßthe former owner. The device is Firmware version 147. In the VRM it shows me, that it is not upgradeble. Error 1342. Now I tried to do an offline upgrade but even that fails without any error.
What do I need to do, to upgrade the device to version 1909209?
Need to add following details:
- RaspBerryPI 3b+ with VenusOS large 3.31
- MPPT 75/10 v1.64
- Multi Control Device for the Inverter
That device is definitely older than 3 year, I guess it is almost 10 years old.
You need a MK2 or MK3 interface and use VEflash.

I have an MK3 and tried already with VEFlash over a Notebook, that is not powered by the Inverter. The MCD was disconetcted for the flashing and the Pi3b was powered by an "UPS".
I always stuck at the change from Part 1 to Part 2. I never got the windows Part 2.
BTW: I am not a professional, but I saved all settings in a file and by screen shots of the VE software.

I also have similar equipment as you, if it works fine, it does not need to be updated to avoid possible malfunctions. The files are otherwise on the page https://professional.victronenergy.com/accounts/login/?next=/
My idea why I would like to update is, that there are assitants in the new version on the one hand and on the other hand I plan to extend the system with a second MPPT (100/30) for two additional solar panels. I hope that the funtionalety in regards of the co-existance between Inverter and MPPT got better in the new firmware.
By now I have: 12/3000/120 MultiPlus, MPPT 75/10, new (not implemented yet) MPPT100/30, VenusOS RPi 3.32, Argodiode Battery Isolator for 3 Batteries.
Further planned is a Victron Shunt to get better system values.
Is it really not werth to upgrade the system?
If you really need assistants,then you really need an update.When I wanted to update my system, Johannes Boonstra from Victron advised me to stay on the current version to avoid irregularities,if the Multi works perfect with old 19... firmware.if you are going to add another mppt to the existing one, and both are smart, connect them to the built-in smart network so that they can talk to each other when charge the battery,adding smart shunt is good idea,for displaying all data on Rpi.This is my off grid system in my cottage,working great for 6 years...
The first 4 numbers after HQ in the serial number will tell us when it was made. This may give more clues about how to update.
