Ok, I tried many things such as wiping data and stuff... I said it didn't work.
But when I flashed GAPPS 4.2.2 Minimal
( @ goo.im/devs/BaNkS/GApps/4.4.2//5-22_GApps_Minimal_4.4.2_signed.zip ) after restoring/wiping ofc... the problem seems to have been solved... for the time being!
If anything happens after this, I will update it;
I don't know if I should edit the post's title to [SOLVED]..
Waiting for other members replies!
