Play Store not registering my phone after root I rooted my phone and after that for the 1st time, as I was just checking out stuff, Google Play recognized my device and registered it.

Later I did a factory reset and now for some reason it is not registering my phone and I cannot download anything! 

Entering the "My apps" section only lists the installed apps. No update options, no all apps section!

What happened? Now what should I do?
Update to latest Play Store.  

Clear Play Store app's Data and Cache.

Reboot your phone. They check whether problem exists or not.
