Samsung S4 Unable to turn wi-fi on
I purchased 2 x S4's in December 13 via Amazon. Both worked ok with no problems, around about April my S4 started having wi-fi problems, it would not always connect to my router. I would have to put in the router id again and then it would be ok. The other phone worked perfectly on the router or at a hotspot etc. Eventually my phone would not switch on so I took it to my local phone guy who reset it. By the time I had got home it had switched off again, after taking it back to the guy again this time it worked ok. I switched the phone off whilst at a meeting and since then it I cannot get the wi-fi to switch on. All this time the other S4 has been perfect.
I checked OS etc on both phones and found that my S4 was running19505XXUFNB8, the good phone was running 19505XXUFNC4 (still is). I tried to root my phone using CF autoroot and Odin to change* ro.securestorage=true* to false (a parameter in build prop) as one forum said this would cure my problem. Although I could change it I could not save it.Super SU would not install properly. Eventually the phone got stuck in a boot loop. Which cleared when I reinstalled * 19505XXUFNB8. Since then I have installed via Odin 19505XXUFNC4 so both phones now have the same os's hoping that this would cure the problem but it is Wi-fi is still not switching on!
How do I turn the wi-fi on?
