    Welcome to Android Central! Try wiping the system cache partition, which won't erase any personal data: Reset: Samsung Galaxy S 4 | T-Mobile Support

    Thanks for the tip, unfortunately did not work for me and tried twice for good measure!
    Device displays a Security Notice :- Your device has blocked an action that is not permitted. No further action is required.
    Wonder if that action is the request to Turn Wifi ON?
    All this has happened since the most recent upgrade via Kies earlier today.
    Thanks in anticipation

    A factory reset would be my advise. Back-up data you want to save before!!

    thanks... looks like I'll have to go that route - if that fails, will try and flash with stock rom

    update:
    factory reset and still the same; unable to select WIFI and the same Security Notice as before!!!

    Hmmm that's a bummer. Maybe it's a HW fault after all. Did you delete the cach as well before factory reset (you can do both if you start the phone in recovery mode). Maybe it can help, not sure.......

    Yes done both the cache partition delete AND factory reset to no avail... also sent Samsung tech an email and visited local EE store.
    Ended up downloading and flashing stock rom from Samsung and...... ALL is WELL again!!
    Curious thing is that the stock rom that I flashed is the SAME version as the troublesome one that was initially installed by KIES, so can only assume that "something was lost in the translation" as they say
    Thanks for your input...
