One of our customers tried updating the firmware of his Multiplus 12/3000 using (initially) VictronConnect and an MK3-USB. This failed halfway, and since then the inverter will show all LEDs flashing when switched on. He tried redoing the update with VE.Configure to no avail, at this point the MK3 won't even see the inverter any more.
I've read through all the posts on this forum that describe a similar issue, but none seem to have a solution for my customer's dilemma.
Is there a way to get the inverter to revert to an older firmware, so we can get it to communicate again? Any other suggestions to recover from this?
Thank you!
