I had the Roborock S6 for a few months now. Everytime I try to update the firmware it gets stuck at some point. Say 25%. After some time, I can select update options again and sometimes it stays stuck at the same value and other times is moves on to a new value say 45%. I go through this a few times before it finally updates. Any ideas as this is VERY annoying.
Hello,
May I know which app you use? Roborock app or Mi home app?
Please go to settings page and click "contact customer service" and click copy all and send us these info as pic attached.
Clear the cache on the app, or reinstall it to have a try.
Also, use cellular data, instead of Wi-Fi and verify whether it works.
