Problem with Google Service, Google Play after Update (in China)

[pinklover91]

Hello, i just bought sony m4 aqua dual from hongkong, i could use my google service.

when i came to maindland china it automatically updated its system.maindland china install something that prevent me from using my google service forever, no matter where i go. i cant use my google service anymore, i cant install anything, use any service without logging on google.

i tried to use VPN, i could open google.com but i cant log in any service and playstore.

i tried to repair software but it seems like it does not fix the problem.

i am planning to go back to indonesia, i can't use my phone if i cant access google.

no one seems to know how can i downgrade or get this back.

Try to perform a software repair using PC Companion when you are already in Indonesia, as far as I know that China is indeed blocking Google services.

I tried to use VPN (United States IP) for the whole thing, and do software repair on PC. 

Using VPN, I could browse google.com, but I can't add account. It always stuck after I input my password, then it crashes all the time. 

Is there any possibility SONY installed something that make my phone unable to use Google Service  forever, wherever I go, my phone will never able to use Google again?

How can I fix this?

Thanks.

As I told you, China is known to block some Google services. I dunno how they do it but I'm sure that it's not done by Sony. And I really think you'll not be able to fix this while you're in China coz it will be blocked again and again.

Try it when you go back to Indonesia.

It can be that your phone won't work in China.

I do not believe that it is something "forever". If nothing else works and SONY support can't help you, you could try reading about FlashTool and TFT files.
