Hi Alejandra, The problem you're seeing is that the software version on your X410(! Not X440) does not match the version that your host-side UHD expects. Your UHD host is at 4.2.1 while your MPM (that's the software on the device) seems to have been at a lower version number. We use compat numbers which do not 1:1 reflect a version number as some changes can be backwards compatible, others are not, and we might have to change the compat numbers more or less often than the version numbers. You mention that you've followed the manual and now the actual value is 5.3. That means that your device is now ahead of your UHD host setup. To match those two, you can either update your host software to the latest release 4.6 or you can install a matching file system image onto your X410. For UHD 4.2.1 you can get all sorts of images here: https://files.ettus.com/binaries/cache/x4xx/meta-ettus-v4.2.0.1/ I'd recommend using the mender image. Download it, unzip it, copy it to your device and run `mender install PATH/TO/IMAGE.mender`. After this has finished, reboot the device, login again and run `mender commit` to make the change persistent.
