V3.60~20: VRM firmware update does not complete

I wanted to check faster firmware update via VRM on my boat with Cerbo, MultiPlus, MPPT and LFP battery (REC BMS). I have reliable LTE connecttion to the boat.

The firmware update hangs in this stage for several minutes:

The it fails with this error:

VRM is set to Full control and there is no errors on Cerbo:

Will try another reboot of Cerbo, just to have a clean state.

Hi @Lure , was this solved? Or is it reproducible?

Thanks for reporting!

Yes, this is still reproducible, have just tried it now.

Note: I have security profile set to Secured. I think the last time I used firmware update in VRM I was still on Unsecured. I might try with Unsecured again over the weekend as I am not sure if this is also causing this problem:

This is still reproducible with v3.60~21, just the error code is different.
