Downgrade Notices

To ensure a smooth firmware downgrade, follow the specified downgrade path until the desired firmware version is reached. Skipping steps may cause errors or loss of functionality. See the Downgrading Paths section below.

Note: Designs that include hardware, features, or properties introduced in a newer Q-SYS Designer Software (QDS) release might not open in older versions of QDS.

Core 8 Flex and Core Nano units with the i226-LM LAN controller cannot be downgraded below v9.12.

When downgrading from firmware version 10.1+ to a pre-10.0 version, you must first downgrade to firmware version 10.0.3 as a bridge. Do not use versions 10.0.0, 10.0.1, or 10.0.2 as the bridge since this can cause the NC Series camera to become stuck in a firmware upgrade loop.

Note: If you run into this problem, upgrade back to 10.1+ to recover, and then use 10.0.3 as the downgrade bridge.

Required Downgrade Path for NC Series Cameras:

10.1+ → 10.0.3 → pre-10.0

Downgrading Paths

Version 10.3 can downgrade directly to any 10.x version (10.2, 10.1, 10.0) or to 9.13.x. The initial firmware package is transferred, and the Core will reboot. After the reboot is complete, manually re-push the design to finish the downgrade process.

To downgrade from 9.13.x to 9.10.x, it is essential to check the "Allow old authentication method for Q-SYS Designer" box in Core Manager. This ensures compatibility with version 9.10.x.

Proceed with the downgrade to version 9.4.x without additional requirements. Access Control will be disabled and User Accounts will be lost.

Note: Core 8 Flex or Core Nano units with serial numbers starting with 21TW2419400001 or 21MX2420300117 (or blue network ports) use an upgraded LAN controller. To avoid network communication problems or instability with Q-LAN, Dante, or AES67, do not downgrade these upgraded units to a version earlier than v9.10.x. If you have already downgraded, we recommend upgrading the firmware back to version 9.10 or later.

When downgrading to version 9.0.x, it is essential to check the "Allow Legacy Unsigned Firmware (9.0.1 or lower)" box in Core Manager to ensure the system functions correctly.

Follow the standard downgrade procedures for versions earlier than 9.0.x.
