so I've been using my Xperia Arc S for over a year with no problems but recently when I try to turn on the wifi it becomes stuck at 'turning on'. The same thing happens with the bluetooth. Sometimes when I restart the phone it works but most of the time it doesn't I've tried factory resetting it and it worked fine for a bit but then became stuck again. I'm running stock 4.0.4 rooted.
It started happening when I went overseas where my sim card didn't work and I had to change the time zone manually in settings. I read somewhere that this happened to someone else who did the same but there was no solution found. Does anyone know how to fix this? Any help will be greatly appreciated, thanks
