How to solve EmergencyData app appearing on Huawei Ascend G630? My Huawei Ascend G630 (G630-U00) only shows an app titled EmergencyData with 2 options and 1 button, all in Chinese.



I can't do anything to close this app or continue using the phone.

How to fix this?
The Chinese text roughly says, 


  The system has detected a corrupted internal storage, please choose from the following operations:
  
  Factory reset
  
  Reboot to this interface


At this point your best bet is to choose Factory reset (wiping your data in the process), click the confirm button down-right, and hope it does its job. If it doesn't, the storage hardware is likely broken and requires taking the phone to repairs.
