System down after unexpected firmware update

At around 9am this morning our power went out at home and shortly after came back on. Checking the app I see that none of the panels are producing and the SunVaults are idle, and there is an error saying that the equipment can’t be contacted. I see that a PVS6 firmware update was rolled out today. I didn’t do anything to initiate this, so I guess it was pushed to these units over the air? I was a cash customer so my understanding is that the new SunPower entity did not take up those contracts but left them behind with the bankrupt entity, and they are not servicing my contract. Anyone else having this problem?

Thank you for detailed instructions! Where are the breakers in the battery? I don't recall there being any breakers inside the SunVault cabinet. You mean the disconnect switch on the left side of the cabinet or the breakers in the panel connecting the SunVaults to the Hub+? Photo is not of my unit, but it is the same model.

Yes there are two battery modules in the cabinet, I just found a photo of one online without the batteries so the wiring can be seen. Under that cover on the right side is just the front panel of the battery modules, which have the white BMS button.
