OK, please run the update again is all I can offer.
New units are 8.1.1.3.23
HW 00-02
When I did the update it took less than a minute. The manual seems to indicate much longer. How long does it take when you do an update on an SDS1202X-E?
I haven't done one for a bit as new units received have the latest FW, but yes only a minute or two and sometimes accompanied with a self boot or two. However I have seen updates fail to take properly at first install and a second installation fixes that.
Generally the
required Self Cal takes much longer that the firmware update.
Updates are something I don't like to hurry or do when we are in storm conditions for fear of a bricked device.
However there are recovery files files available now for us dealers to get units up and running again but they are
not for public distribution.
Should a feature not work as it has before or a new feature in the changelog not be added into the UI then running the FW install again IME always fixes it.
It gets a little more complex when an OS upgrade is offered in that they are optional but without installing it some new features like the improved Webserver for SDS1004X-E in it's new FW won't be activated.
Just follow the FW install instructions given by Siglent and all goes well.
