Update firmware fails with error 004

Last modified date: 2022-06-24

Applied Products:

All NAS Series
All QTS Firmware Versions

While trying to update firmware, it may fail with error FW004. In that case, it is recommended to download the firmware image directly from QNAP website, so later you can upload it manually through Qfinder Pro > Tools > Update Firmware, then upgrading the firmware this way.

If above still fails, another reason may be the NAS DOM is defective, and will need to contact QNAP Support to verify, as the NAS will possibly need to be repaired.
