I'm trying to do an OTA update on a device (Zooz ZSE42). I've uploaded the .gbl file to the File Manager and launched the update app. I get this screen:
I've run into that recently too... Try uninstalling & reinstalling the Device Firmware Updater app -- you won't lose any of your library files when you do that.
Thanks for the info. I just uninstalled and then re-installed the app and it no longer shows up in Apps list!? If I go back to built-in Apps and attempt to select it again, it then runs the app.
Anyone know why this no longer showing up in the Apps list?
