According to your description, your cube is in test mode by accident now. So we suggest you to follow the steps below to pass the test automatic.
1.Remember your original Wi-Fi name and password.
2.Reset your WiFi system: change your wifi name to “Sugr”(the first letter of “S” should be capital letter), and set the wifi password as ”nicainicai”.
3.Reset your Cube again by poking the reset button next to the USB interface on Cube.
4.Connect your Cube with the wifi you changed via app "Sugr Cube" in your phone.
5.When you hear other Chinese saying which should be different from the previous one ( means the test is successful), pls wait , the Cube is rebooting and will enter the general mode.
6.After the Cube is powered on again, update the firmware with your Sugr Cube App.
7.Received the info “ update successful”, please check the version and confirm it.
8.Restore your Wi-Fi name and password to your original one then.
After doing all the steps above ， you can use your Sugr Cube regularly as before.
