To save time, I moved all my ADB files to the same folder as my bcmdhb.ko and any other phone related file boot.img's, and more. Now using CMD and adb enter the command: adb push /users//Desktop/bcmdhd.ko /system/lib/modules (You'll need root access and a root file explorer)ĭownload the appropriate file for your phone, boot your phone into recovery/fastboot and plug it into your computer. Try finding and replacing the file named bcmdhb.ko located in /system/lib/modules. Turns out the problem was as simple as a faulty file in the Android system. My Wi-Fi always showed 'Turning on' but never did, and my MAC address showed 'Unavailable'. I too had the same issue after I flashed a new kernel to my HTC Vivid.
