Help needed to possibly fix wifi issue

I have an LG G2 D801 which was rooted and running custom rom CloudyG2 2.2(KitKat), I tried to ugrade to CloudyG2 3.3(Lollipop) but may have messed up somewhere and ever since my Wifi and Bluetooth's MAC address has been unavailable. I've been reading around and people are saying it's a hardware issue so it won't be fixed unless a new motherboard has been replaced but i've come across a thread saying the 'bcmdhb.ko' file may need replacing. It's located in System>lib>modules but i realized it's not there. I'm hoping someone could upload or mail me the file so i can try my luck or hell even give a possible fix. Thanks in advance. Currently back on CloudyG2 2.2

Is there any way i could possibly recover my files on xperia z1? Internal memory.

I updated it via sony pc companion but then boom it crashed so i had to reformat it. Please please im desperate. I need those files back badly. Is there any way? Thank you guys
