Default Wifi Issue on Omega V21

Hi guys,

I just rooted my phone from 4.3 stock to Omega v21. I have been having wifi issues since upgrading to 4.3 official so I decided to root and flash custom ROM thinking it would help. The problem however, still remains.

The problem is that wifi will not switch on. The button itself moves but does nothing else. It has switched on a couple of times after manually rebooting over and over, and works for a few seconds then back to square one.

I have flashed the bootloader, modem, and ROM multiple times without any change. I have also opened the casing and lifted the gold antennas ever so slightly to no avail.

Any help will be much appreciated. Cheers!
