Qmobile z4 mini flash file needed damn badly

I am a flasher and yesterday I received Qmobile Z4 mini , phone was stuck on logo , so I downloaded a flash file from internet and flash with it ,
Now each thing been working flawlessly but call dialling .
As I dial any call phone gets restart itself.
Hard reset didn’t solve issue.
Could someone please upload tested file for Qmobile Z4 mini .
Thanks ! Cheers
