tab 3 10.1 - can't turn on wifi
recently been trying to enable wifi on my tablet, replacing the wpa_supplicant file, since the first replacement the wifi won't turn on anymore. you flick the little switch and it says "turning on..." then it stops.
is this just 'cos the supplicant file is no good? i've tried 3 different ones with the same results. i also tried a failed root before i did it successfully, could this be the cause instead (can't update samsung because "device has been modified" - it shouldn't supposed to be able to tell apparently).
can't just put the old supplicant back either because it's disappeared, folder i created and put it in on tablet is gone.
