I was using CM12 on my device for quite some time and everything was working fine. Then I decided to flash CM12.1 and coincidentally, it was the a couple days after CM had announced their discontinuation of CM ROMs. After flashing the ROM all of my WiFi, Bluetooth and Cellular were not working when booted in CM12.1. I thought it was the ROM's bug and then clean flashed the old CM12, but my my WiFi, Bluetooth and Cellular were still not working! So I flashed my device's original firmware like I always did using flashtool "C2104_15.3.A.1.17_Generic". WiFi, Bluetooth and Cellular were still not working in the now 4.2.2. I tried various ROMs - LOS14.1, CM13, Resurrection remix but no luck, my wireless utilities are still not working. Do you know how to solve this? I don't have any data on the device so I am prepared to use any tools/techniques to get the wireless utilities back.
