Voice PE updates failing since some version

[nocturne flax]

I have 2 HA VPEs that I could update via a button in Home Assistant for most of last year. Since recently this stopped working and I don't get any feedback why.

When I try to update form ESPHome, I get an error: ERROR Error binary size: Error: The OTA partition on the ESP is too small. ESPHome needs to resize this partition, please flash over USB.
Could this be the error that prevents the update from HA but it's not visible anywhere? (I use container deployment, but I don't see anything in the logs)
HA is currently on: 2025.12.5

your using the builder tool? what customisations have you made?

None. I only tried with esphome since I was hoping I get better errros than I got form HA

substitutions:
  name: home-assistant-voice-09d577
  friendly_name: HA VPE - Bedroom
packages:
  Nabu Casa.Home Assistant Voice PE: github://esphome/home-assistant-voice-pe/home-assistant-voice.yaml
esphome:
  name: ${name}
  name_add_mac_suffix: false
  friendly_name: ${friendly_name}
api:

wifi:
  ssid: !secret wifi_ssid
  password: !secret wifi_password

it's really just the very base setup

Plug it into your PC via USB and flash it using THIS tool as per THESE instructions.

This will move you back to stock firmware and you can remove it from the builder tool. unless you need to customise stuff then there is no reason to use the builder tool.

I don't think I ever successfully updated iwth anything but buttons in HA, but I'll try. I really only care about them working for default things

ohh, interesting. It also solved the issue with my Assistant not working anymore. Thx
