While trying to complete a firmware update to a new Multiplus Compact 12/2000/80/120 via VictronConnect (laptop connection via MK3-USB) the update failed (no error code given). Now the unit shows a rapid blinking yellow "charger" light. The MK3-USB device cannot establish a connect through any of the toolkit software (VEFlash, etc.). Not sure where to go from here to troubleshoot the issue further. Submitted a help request for distributor support but hoping the group here has more ideas.
