Can't add google account after phone reset I have a leagoo lead3 running android 4.4 and after factory resetting it I'm no able to add my google account.

The error I receive is "Couldn't sign in" " There was a problem comminicating with Google servers. Try again later."

Googling I find that hosts file in /system/etc needed to be modified to comment out "xxx.xxx.xxx.xxx android.clients.Google.com" but I don't have this line.

Also I checked http traffic with fiddler and I just have this :

"200 HTTP Tunnel to 173.194.40.142:443" with body 0

It seems to be a good google ip. I don't what to check now... Any help will be appreciated.

Thanks
According to this post on Google Forums:


Check if two-step  verification been enabled on the account (https://support.google.com/accounts/answer/185833?hl=en&amp;ref_topic=2784804)?
Try to open a browser on the device, go to https://mail.google.com/ and sign into your account.
Also try the Unlock Captcha function (http://mail.google.com/support/bin/answer.py?answer=78754):  https://www.google.com/accounts/DisplayUnlockCaptcha
You can try disabling IMAP (from the web-interface) and re-enabled it.  Or deleting the account from the device and setting it up again.



  NOTE:  When two-step verification is enabled for an account, you need
  to create an application specific password (to be used in place of
  your regular password) for any client/application/device that doesn't
  know how to ask for the 2-step code (like your phone).

Other possible solutions:


[XDA Developers][Solved] can't acces/sign in google account after factory reset
[AndroidForums][SOLUTION]Cannot add Google account after factory reset


The first one works if you can't estabilish connection to Google servers, the second one needs rooting the phone (Remember: you do it only on your own risk)

Hope it help
