How to Request Firmware or Application Software for a Legacy QNAP NAS

Last modified date: 2026-09-18

Applicable Products

Legacy QNAP NAS models, including models such as the TS-419P+

Overview

If you need a firmware file or application software package for a legacy QNAP NAS and cannot find the required release on the public QNAP download pages, open a support ticket with QNAP. The support team can check the model, identify the appropriate package, and provide the file or further instructions when it is available.

This guidance applies to requests for legacy NAS firmware and application software, including QPKG packages or other software that is no longer publicly listed. The availability of an archived package, its compatibility, and the supported installation method must be confirmed by QNAP Support.

Do not install a package intended for another NAS model, CPU architecture, operating system, or firmware branch.

Scenario

A user owns a legacy QNAP NAS, such as a TS-419P+, and needs an older firmware release or application software package that is no longer visible in the public download area or cannot be located through a web search. The user should contact QNAP Support through the Service Portal and request assistance for the exact NAS model and software package.

How to Contact QNAP Support

Open the QNAP Support Service Portal.
Sign in with a QNAP account or create one if necessary.
Create a support ticket for the legacy NAS firmware or application software request.
Include the following information:
- NAS model and hardware revision, if known
- NAS serial number
- Current QTS firmware version, if the NAS is accessible
- The exact firmware version, application name, or QPKG version requested
- The reason for needing the package, such as recovery, migration, or reinstalling an application
- The NAS region and language, if relevant
- A description of the current situation and any error messages
Ask QNAP Support to confirm the correct package and provide the official download or delivery method.

QNAP Support may request additional information to verify the device and determine whether the requested firmware or application software is compatible with the NAS.

Before Applying Firmware or Application Software

Confirm that the package is specifically intended for the exact NAS model and hardware revision.
Verify the firmware or application version, CPU architecture, dependencies, and release notes with QNAP Support.
Back up important data and record the current NAS configuration.
Follow the installation instructions provided by QNAP Support.
Do not interrupt power or network connectivity during a firmware update.
Do not remove or replace an existing application until support confirms that the requested package can be installed safely.

Validation

After the update, recovery procedure, or application installation is complete:

Sign in to QTS.
Open Control Panel > System > System Status to confirm the NAS model and firmware version.
If application software was installed, open App Center and confirm that the application is installed and reports the expected version.
Confirm that storage pools, shared folders, and required services are available.
If the NAS does not boot normally, the application does not start, or the version is not as expected, stop further installation attempts and update the existing support ticket with the result.

Warning
Firmware or application software intended for a different QNAP model, CPU architecture, or firmware branch can make the NAS or application inoperable. Only use a package supplied or explicitly confirmed by QNAP Support for the target NAS.
