play store error 491 and apps force close

Hello

I bought a new Asus Padfone X

I'm from Europe (Romania,home of Dracula and Nadia Comaneci)

It came unlocked with the AT&T firmware (with a lot of bloatware on it) Androil version 4.4.2.

I rooted the device in order to have freedom to remove the bloatware and add more longevivity on battery life.

The google "solutions" didn't help me.

Does it need to install a new and clean firmare?

If yes,on the official site's support section of this product doesn't offer the firmware as you can see for yourself by following this link http://www.asus.com/us/Phones/ASUS_PadFo...

Can you help me with this issue ? or by giving me the WW fimware version?
