As the release note of firmware 1.1.0 says: upgrading to 1.1.0 will restore the controller in AP mode — this is because 1.1.0 uses a different flash layout, so it will not preserve the WiFi settings. If you hear beeping sound, that means it’s in AP mode (it’s not bricked, otherwise you won’t even hear the beeping sound), you just have to repeat the WiFi setup step to get it log on to your WiFi router again.
