hi I have a SGSII and I flash miui 2.4.6 but I can not log in with my google account and sync my details. it takes a long time and it show signing in, but it never sign in.after a while it said: couldn't sign in: cant establish a reliable connection to the server. this could be a temporary problem or your Android device may not be provisioned for data services. if it's continues, call Customer Care. sorry me with my poor english.
