It happened to me only once that a camera crashed after an update and I have been testing all beta firmwares for about 2 years on all my cams each time. (don’t do that😜) This camera that crashed during the update was revived by firmware flashing so I’ve never had a defective camera after an update. I have seen the unknown status before. When it is happening, I let the camera go for about fifteen minutes and see if that solved the problem. I have also had to unplug the camera and plug it back in and then try the update again. This always solved the problem except once. (cam above)
I think people are often too quick. When the update doesn’t seem to be going well, they will try anything instead of waiting for the process to complete. When you see a message that the operation failed and to reboot your camera(your picture), wait 10 minutes before doing so. If you see that nothing happens, do it and then start the update again. You will see the unknown status in the bulk update section as long as the camera has failed to connect. I’m not sure if this status is refreshed if you stay on the page. Just go in the device info section to see if the update was successful. If it was, you will see the correct firmware in the bulk section of this cam instead of the unknown status message at the bottom of the page.
I actually get the same info you do when it comes to the bug fixes, however the firmware that was paused is linked again in there which makes me believe at some point it was un-paused so I will dig and see what I can find out
If you have not tried this, try clearing the Cache from the app (Account > App Settings > Clear Cache) and then log out of the app, reboot the phone and then logon and connect to the Camera. See if it come back online.This has corrected issues like this a few times, but not 100% of the time.
