Unable to update Danfoss Ally TRV

[johnsprogs]

I'm trying to update my Danfoss Ally TRV's from version 1.02 to 1.08. When uploading is ready, progress reports 'done'. But after a minute or so, the upload starts all over again. I'm running DeCONZ 2.13.2. First tried it using the DeCONZ installation on my Domoticz Raspberry Pi. Then installed a fresh DeCONZ on a Windows machine, tried again from there, but with the same result.
Here is my setting:

The debug log reports following at the end of an upload:

My questions to start with are:

Line 8 states: 'invalid update end request'. Says who? DeCONZ or the TRV?

Line 4 states 'otau query next img req:'. When no uploading is being done, this request comes about every minute. And am I right that it is requesting for version 1.02? But as far as I know, that's already there.

The otau cluster:

And shouldn't some of this figures below appear in the second frame (Upgrade and respomse) of the otau-cluster?

Or do I have to transfer this figures manually and then press execute after a full upload?

If you want more specific info, or want me to try something, just let me know.

Thanks in advance for your effort.

No, it doesn’t. The OTAU Plugin invalidates the update, after the TRV ended the upgrade on line 2. Looks like the TRV didn’t like the block it received before. Did you double check the checksum of the image file?

Line 4 states 'otau query next img req:'. When no uploading is being done, this request comes about every minute. And am I right that it is requesting for version 1.02? But as far as I know, that's already there.

The TRV reports it’s current firmware in the request for a next version. It wouldn’t know what next version to request, would it? Note that this request comes from a different TRV. I think the plugin sends a no image available since it’s still upgrading the other TRV. It only handles one device at a time, not to saturate the Zigbee network.
