Thanks for the info.
I solved it by installing PrebuiltGmsCore.apk from here * can't post the link...
Thanks again,

Thanks a lot, you saved me with the hint. Without google account on phone, phone is almost useless, can't get all my contacts, can't install any app from play store and no gmail.
Well, I didn't find link for this PrebuiltGmsCore.apk on this post but after some search I found this gapps zip which contains PrebuiltGmsCore.apk inside system\priv-app folder. just extract it and install. That will install Google Play Services and then you should able to add google account.
ps: google play services frequently keep crashing but not sure yet if some additional dependency require. I will try cleaning cache and data and try adding account again.
