Well for now I stick to Luna, although I don't like the user interface at least it works.
About the factory reset to get the "normal" versions to work, it is a brand new phone and the first attempt to install and run an nextgen version that works perfectly on my wife's Samsung- failed!
Well it installs but refuse to run, it just quits.
My point is, a brand new phone is the same a a factory reset phone I guess.
I've seen there is a Android update in India" so it is to expect there will be an update here sometime too, I might try again after that,
