couldn't sign in/there was a problem communicating with Google servers - Xiaomi Redmi 2 Pro

Question

I have a new Redmi 2 Pro and I am unable to sign in to my google account.
I have Android 4.4.4 KTU84P version and MIUI 77.00.99.



I'v already tried to login with other google accounts, I disabled 2-step-verification and DisplayUnlockCaptcha. I Cleared data/cache of play store, account manager, service framework. All tries were unsuccessful.
I can login to my gmail through the browser on my phone.



The error message: Couldn't sign in/There was a problem communicating with Google servers/ Try again.



Apps used to sign in: Google Account Manager 4.4.4-1227136 and Google Play store version 5.4.12 (these apps are initially installed on the phone)



Steps to sign in on the phone:




  1. Add google account -> Existing account -> user+password -> error message


  2. Start Google Play Store -> Existing account -> user+password -> error message




UPDATE



After a long night search, I found out that the phone came with a vendor specific ROM, namely 77.00.99.00. The official version looks like 7.1.0.0. So, I'm thinking to flash the ROM. I have no idea what else is installed beside the official package.

Answer

Actually the problem was with the ROM, Gearbest replaced the official one with a buggy one. I flashed the latest stable global ROM MIUI 7.1.1.0 with a little trick described by Bilhouse in the miui global forum here



The steps are as follows:




  1. downloaded the Latest Stable Global ROM from here for Redmi 2 version 2014813
    file: wt88047_global_images_V7.1.1.0.KHJMICK_20151209.0000.6_4.4_global


  2. downloaded the China ROM for mobile version 2014811, I used the one mentioned in this post here. file name wt86047_images_5.4.3_4.4_cn_94aabfc129


  3. from the China ROM I copied NON-HLOS.bin file and replaced the one in the Global ROM - if you don't do this than you wont have a functional network module and you wont be able to connect to any network.


  4. Flashed the ROM with fastbool as described in my first link.


  5. At my first try of flashing, I encountered an error massage: mismatching image and device in fastboot, which I solved by changing the name of the folder from wt88047... to wt86047... after this I was able to flash the ROM and tired again but this time the folder name should start as ti was originally wt88047...
