- Trigger an update with deltas enabled between release A and release B on a test device.
- Find the delta image that gets pulled from balena images -- it should be REGISTRY_URL:DELTA_TAG
- Alternatively, if running Supervisor v12.9.5 or greater (12.9.6 highly recommended), look in the Supervisor's journal logs.
- Alternatively, make a request the delta endpoint with
curl -H "Bearer: Authorization $(cat /mnt/boot/config.json | jq -r '.deviceApiKey)" "https://delta.balena-cloud.com/api/v3/delta?src=SOURCE_REGISTRY_URL&dest=TARGET_REGISTRY_URL". This should return the delta URL and is the best amongst these 3 alternatives, but from my own investigations and limited knowledge, this works sporadically so is not recommended.
- After you have the registry delta URL, on production devices:
balena login registry2.balena-cloud.com -u d_$(cat /mnt/boot/config.json | jq -r '.uuid') -p $(cat /mnt/boot/config.json | jq -r '.deviceApiKey')balena pull DELTA_URL- `balena image tag DELTA_URL

Instructions for how to restore a corrupt /etc/resin-supervisor/supervisor.conf
For all commands below, if OS is v2.78.0 or newer, replace resin-supervisor with balena-supervisor. See: https://github.com/balena-os/meta-balena/blob/master/CHANGELOG.md#v2780
cat /etc/resin-supervisor/supervisor.confshould show corrupted file.- Verify no other files are corrupt with
grep -v "/var/cache/ldconfig/aux-cache" /resinos.fingerprint | md5sum --quiet -c -See: https://www.balena.io/docs/learn/more/masterclasses/device-debugging/#112-storage-media-corruption - Note last reboot time and when the device was observed to stop working (i.e. Supervisor could not start), notify support agents if possible
- From the dashboard page, open Chrome / Firefox developer's console with Ctrl/Cmd + Shift + I. Run the following:

Preload any Supervisor onto balenaOS image
Replace loopN with loop number listed with partx command
balena os download raspberrypi4-64 -o rpi4.img
losetup -fP --show rpi4.img
mount /dev/loopNp6 $MOUNTPOINT
If the mount fails with wrong fs type or similar, this is most likely because the image is a flasher image (i.e. for Intel NUC, for example), and you will need to do the following:
