S4 wifi issues when switching on.

[kris_stuart69]

Hi

I have just connected my phone to Kies and upgraded to the latest firmware that was available. Now when I switch on the wifi it switches back off and I get a message telling me "The device has detected an application attempting unpermitted action and has stopped".

The device was rooted before the upgrade was applied.

Anyone know how to fix this?

Maybe you got a non-supported app at some point? Did you try a factory reset?

I have now done a factory reset and when the phone is setting up for 1st use it does the same. The wifi will not switch on. :-(
