I recently restored stock rom on my Samsung galaxy s4 GT-i9505 from cm11. After that, the wifi just will not turn on at all. I will get a notice when i try to turn it on. I cannot upload a screenshot of the notice i get, it says "Security notice Your device's security has blocked an action that is not permitted. No further action is required."
Please help me solve this issue if it is possible. I really hope i have not screwed up my phone
Any form of help will be greatly appreciated.
Edit: I got it to work already. i guess i flashed the wrong rom on my phone. i would like to thank @samersh72
