If you can check the EMO App, have a look under FIRMWARE and see if the UPDATE FIRMWARE button is present.
If it is, and EMO is going in a look (mainly on Step 1). It might be a problem with your WIFI/Home Network not being stable enough.
Check out my video give here for more info on how to install the Firmware Vers 2.2.0 >> EMO Firmware Update Version 2.2.0 Video
Hope this helps
