Exclamation [Q] Wi-Fi not working after TWRP and root

Hi, guys. I figured i could write here.

The situation:
I installed TWRP on my phone with B512 which I got through official online update. Everything went fine but the phone didn't seem rooted so I rooted it with the vRoot (the 6th method) and after a restart I can't turn on Wi-Fi.
I have since tried getting the stock recovery and factory reset and nothing helped. Does anyone have a clue?

Any help will be appreciated

EDIT: I figured it out. Can somebody tell me how to delete/lock this thread?
