Trying to update.

[C4Wiz]

i just installed Home Assistant on a Khadas vim3 using the 15.2 rescue image, works great, when i go to update it says none available.

looking through the logs i found this:

2025-11-13 16:49:34.806 INFO (MainThread) [supervisor.os.manager] Fetch OTA update from https://os-artifacts.home-assistant.io/16.3/haos_vim3-16.3.raucb
2025-11-13 16:49:35.192 ERROR (MainThread) [supervisor.os.manager] Error raised from OTA Webserver: 404

and

2025-11-13 16:53:44.705 WARNING (MainThread) [supervisor.updater] Board 'vim3' not found in version file. No OS updates.

looking at the url on the github page i noticed ithe update file is named: haos_khadas-vim3-16.3.raucb but the updater is looking for haos_vim3-16.3.raucb.

how can i fix this?

i Fixed it.

for anyone facing this issue: https://docs.khadas.com/software/oowow/user-manual
you can push the HAimage over lan:

first change firewall settings:

Firewall
Network → Firewall Mode:

block - Block all incoming connections SECURE (Default)
allow - Allow incoming connections from local networks RECOMMENDED
disabled - Allow all connections, firewall disabled DANGER

then:

curl OOWOW_HOST_NAME_OR_IP/shell/write | sh -s - IMAGE
