Hi all, greetings from Denmark 😊

i have a bosch powerpack 400 battery and i found a diode burned and i have replaced that now the board is alive.

The light 2 and 4 blinks and shots off. I have try to reset by holding button for 10 sek but that is still the same.

I have taken BMS out and applied external 3.3V after voltage converter and only diode 2 and 4 blinks.

Some YouTube videos says it could be software error but i dont know where to find the firmware and how to update.

Anyone have knowledge about what it can be?

Thank you very much

Its most likely that something else is broken too, beside the diode!
You can't easily flash the eprom or change any software, you need the bosch diagnosis tool that some dealers use.

You can look for some YT-Video from "Hardware Junkie" - he is an expert in Bosch BMS and has repaired many batteries like that. Very common are problems with the voltage regulator that should supply 5 V, but could also be a fuse or something like that.
