Unable to reach Google Play does not recognize my device I have the HUAWEI G520-5000 mobile phone which was bought in April 2013 from China during a business trip. The device, despite of being locked for China Mobile carrier, is working properly for my carrier (Cosmote) in Greece. I don't have problems with talking or accessing the internet. My problem is that my Google account does not recognize my device and I can not use the Google Play store and it is impossible to install even the simpliest application. I suppose that the problem is the Android OS on my device which seems to be modified by China Mobile and Huawei (only Chinese apps are accepted by the device and the s/n of the OS is also pretty strange (something like 123456ABCD). 
I would appreciate if somebody could help me out with my problem. Thanks
The following worked for me, but requires root:


install Total Commander
open it
browse to /system/etc
look for a file named hosts
long-press the file, then chose to edit it via the CMD editor
comment out the second line (place a # in front of the digit)
save the file (approve superuser request for Total Commander when asked for)


Now the problem should be solved!
