Have you figured out solution for ur problem? I have same issue although issue was there with different rom also earlier.Hey i just installed havac os but my Wi-Fi and Bluetooth have stopped working. while rooting around in the settings i found that both my ip address and mac address shows up as unavailable. I don't know if that's relevant to the issue but who knows ?.
Any advice would be appreciated.
From what I know there is partition in Android os called persist which has device specific or unique parameters like Mac IDs and all. When that partition is messed up such issue comes. I still don't know how to solve this issue. So any inputs in this regards would be highly appreciated.
