E74 — NVS_SAVED_STATE_DELETE_FAILED

Deleting the saved state entry from NVS failed.

What happens​

The error is logged once per boot and the caller continues. The stale NVS entry remains and may be loaded on the next boot.

Possible causes​

  • The NVS partition is corrupted and cannot process delete operations.
  • The entry did not exist in NVS, but the delete operation still returned an error.

How to fix​

  1. Reboot the device — The stale state may be handled gracefully on the next boot and the delete retried.
  2. Erase NVS and reflash — A full flash erase removes all NVS entries including the stuck one.
  3. Contact support — Open an issue on GitHub if this appears consistently.
