a 6ya expert can help you resolve that issue over the phone in a minute or two.
best thing about this new service is that you are never placed on hold and get to talk to real repairmen in the US.
the service is completely free and covers almost anything you can think of (from cars to computers, handyman, and even drones).
click here to download the app (for users in the US for now) and get all the help you need.

I just had this same problem - I suspect it may have been a new app I installed that changed some settings.
I fixed mine by going into Settings>Mobile Network settings, then tick "Use packet data". Worth a try.

Guys I had the same problem with the k599 Sciphone and none of the solutions found on the internet helped me. New chinese models tend to restart after testing is over and this results in turning the wifi application on. So I spent many hours on thinking how to bypass this function and this morning I woke up with an idea that really worked!! The steps are quite similar with the ones followed to debug older models:
put 2 chips on cell
1-enter in factory mode *#3646633#
2-go to RF Test Tool
3-choose GSM, confirm OK!
4-go to Power scan
5-Select Band DCS1800 click OK
6-the cell frozen
7-wait for 3 minutes testing
8-while testing connect to a pc using the USB cable (do NOT select ANY of the options appearing on the cell screen)
9-Click the CENTER button of the cell until you go back to principal menu
10-go to settings/network settings and choose GSM Preferred or any other option (except WLAN only!!)
In this way the cell does not reboot, and the wifi application stays off, so the option can now be changed...
Hope this helps!
