HomeAssistant Green - unable to reset or see any output other than white led

Installation

Hello all - new poster here. Setup HomeAssistant Green last month and was working great with integrations and automations, however last week I went to apply one of the updates (I don’t recall which one it was) that was prompting within the HomeAssistant app at the top of Settings, and the device has been unrecoverable since then. I found it with only a white LED lit solid; no yellow nor green LED.

Since then, I tried simple power-cycles, and have tried Resetting HomeAssistant Green using both the newer method (hold power button when connecting power, as documented here) and the SD-card method (download and flash the HomeAssistant OS to an SD Card with Balena Etcher, insert SD Card to HA Green device, as documented here). No luck - I still am always just met with a single white LED.

I have tried hooking up display to HDMI Port and see nothing ever. I did see a post about possibly needing to insert a CR2032 battery to HA Green, which I have also done (made sure positive side is up); no change in behavior.

I have a few backups made before the attempted update that seems to have bricked the hardware - but I am unsure how or if I can even use that in the current situation where the device only registers white/power LED and nothing else.

Does anyone have ideas on what else to try to get HomeAssistant Green device working again?

Hi Chris

I am in the same situation to you, although I came to it via a very different route.

I set up my Home Assistant Green and was just getting everything set up and was starting to really enjoy it. I went away on a business trip which was extended for entertainment reasons and when I got back, I could not remember my login - As in my main log-in to the system. All that I have been able to find online says that the only solution is to re-flash the unit. No big deal. I’ve flashed many, many RPi’s for various reasons. However, I find myself in the same situation with the same symptoms as you are experiencing.

Admittedly this was a few months ago before the real Silly Season, but I’m starting to look back into the issue and hopefully get HA running.

I am watching this thread hoping someone posts a solution.
