Downgrade QTS Hero h5.3.0.3145 build 20250530

I was under the impression that Hero could not be downgraded from one versions to an older version. I’m having connection speed issues (very slow) with h5.3.0.3145 build 20250530 and would like to downgrade to h5.2.4.3079 build 20250321 on a TVS-1288 and a TVS 1688. I have both image files.

Versions can be downgraded unless an update notice does explicitly exclude this (if something in disk/OS management has changed significantly)

Hi @NAS-JIM

We’re sorry to hear you’re experiencing performance issues after the update and are considering a downgrade. To help us understand your situation better, could you please tell us:

  • How are you currently connecting to your NAS (e.g., local network, remote access, specific protocol)?
  • What is your network environment (e.g., 1GbE, 2.5GbE, 10GbE)?

Regarding downgrading, please be aware that it can lead to unexpected issues, especially concerning app version. If you wish to proceed with a downgrade, we strongly recommend contacting our customer support team directly. They can provide assistance and ensure the process is handled correctly to minimize potential problems.

Thank you!
