IEDV Version Reverting Issue – Summary & Suggestions

• After reboot, version reverted from 1.22.3 to 1.21.1 – this is not expected.

• Possible reasons:

  • Firmware update wasn’t finalized properly.

  • Device may have booted from a fallback partition.

  • Reboot happened too early during the update.

• If you can’t reinstall 1.22.3:

  • There may be leftover temp data blocking the update.

  • Logs may show rollback or validation errors.

What You Can Do:

• Check system logs right after reboot for any rollback message.

• Try reinstalling 1.22.3 with full permissions.

• Ensure there’s enough storage and no network/firewall interruptions.

• If still blocked, it could be a firmware bug – escalate to vendor or support.

Hi Petr,

we have a bug in IEVD v1.22.3-1-a which causes IEVD's update sporadically to fail if it has too many apps installed on it.

Please try the following:

- backup your device from IEM side

- backup all apps installed on IEVD manually (especially the very important ones e.g. IIH Essentials, Connector configs, etc)

- uninstall all applications

- update IEVD

- restore backup from IEM to IEVD

This should do the trick.

Best,

Pascal

Hello,

Is there a way to check if the IEDV backup from IEMV side I created is complete? When I ran the backup process, both IEMV and IEDV finished with a ‘task status: failed,’ but under Menu → Devices → Backup, there’s no indication that the backup is corrupted or incomplete.”

Best regards,

Petr
