Rooted ZTE GRAND X2 NOT INSTALLING APPS AFTER UNROOTING IT

Hello,
This is Francis K. Ntembula from Zambia, I’m a user of a ZTE Grand X2.
My device stopped installing Applications after it was rooted, I wanted to get rid of some inbuilt Applications which I had no use for but I mistakenly deleted the system file which allows applications to be installed on the phone.
Since then my phone no longer installs applications, an application can be downloaded from the Google play store but when it gets to the point of being installed an unexpected error just pops up and the process just ends there.
Kindly assist me on how I can fix my ZTE Grand X2 so it can start installing applications once again.

Un-rooting stock rom would make Gearvr work again ?

I used to have a rooted Lollipop stock rom and then got the gearvr and it didnt work until I re-flashed the un-rooted firmware again , this caused me to reinstall everything from scratch , now a friend suggested i should try un-rooting option found in KingUser or SuperUser whenever I needed to use Gearvr (untested , just a thought).

so anybody tried this ?

I just dont want to have to reinstall everything once more , its pretty much annoying :)

Thanks in advance :)
