Hi,

Please help me in downgrading my UZB to version 5.6. I tried everything, and nearly all versions of z-way but I can only downgrade down to 5.7, not lower. I know it is an old version but it is the only version that is currently fully supported by HomeSeer, and I need it to restore my Z-Wave network.

Only other option is to start over and include 60 devices again... some of them very hard to reach. Thanks!!

Regards, Stefan.

I found a post that a downgrade from 5.16 to 5.6 is possible (here: viewtopic.php?t=25346#p70243) however I cannot find a version of z-way server that allows me to upgrade to 5.16 first. Has this option been pulled since that post?

Thanks again.

It was temporarily disabled. Will come back in May

Thanks, that is great news! Any change I can downgrade sooner?

Looking here I see that you should downgrade first to 5.06

Sorry, I have been looking at this diagram for a long time but I don't see any downgrade path to 5.(0)6. Can you be a it more specific?

Thanks!

There is UZB/5.16/29304 -> UZB/5.6/29304, but in your case you might have a newer bootloader (after last /). We never expected people might want to downgrade so much.

But I think you can upgrade edit the HTTP request the page is doing (open browser console), change the bootloader CRC to 29304 and download the file.manually. Then use to upgrade using a file.

Thanks PoltoS for helping me. And I do consider myself an advanced user, but I need more specific instructions to make this work. On which page do I need to open the browser console and were do I find the http request and change the CRC in order to download the file manually?

Thanks!

On the Upgrade page (where it show s you "yours is the latest"). Open browser network console and refresh the page
