Firmware version remains unchanged after "successful" upgrade: MultiPlus 48/5000/70-100

I would like to upgrade the Multiplus unit in my Easysolar I from firmware version v494 to the most recent version v552 that is presented on the remote firmware update page. I followed the process (remote update via VRM), got the thumbs-up for a successful upgrade, then uploaded the updated VE Config remote setting file. Everything went smoothly- no errors, no incompatibility message- nothing.


However, the firmware version remains the same: at v494 with no error message or alert of any kind. In my event log, it says "Firmware update - vader- Update firmware for MultiPlus 48/5000/70-100 from version '494' to version '552'", and "Remote VEConfigure upload - VEConfigure file uploaded". What could be amiss here?

vrm firmware update

Does it remain at v494 in the VRM device list? Have you checked trough the remote console if the inverter itself reports v494 as well, or has it changed to v552?

The firmware stays at V494- very puzzling. I did a manual restart after each attempt to upgrade attempt- still at V494.
