Unhappy [Q] [Help] Can't establish reliable data connection

Hi,

I am on BB 71, Fxp kernal, MiUI black editionHD rom and now I am facing this error of not able to log into the google ac form my phone.

I am able to browse the data on a browser but not through any applications like the XDA nor market etc... I tried all the tricks from this forum like a complete fresh install from the BaseBand till the application, also through youtube login but none of these seems to work out.
I have also tried the MIUI data drop patch, All these still prove to be useless as I am unable to login to the google account.

Anyone with the same experience??
