Just had the Z10 (STL100-1) for 2 days.
Upgraded to Z10_10.2.01.2228_STL100-1 the day I got it.
Wifi was working, but had difficult time staying connected and it would hang up as well.
And today the Wifi does not turn ON at all.
I have since rebooted many times, removed battery.
Reimaged with different versions like z10STL1-10.2.1.2234OS+2235Radio and Z10_10.2.01.2228_STL100-1
But I think it is a hardware issue now.
Very disappointed to end up with a lemon.
This was my first BlackBerry.
Maybe you should have used the phone on the OS it came with first? Did it work? Because when you return it with a leaked OS you are gonna have some explaining to do.
Yes.. newer version will raise eyebrows
So I will downgrade to say Autoloader.Z10.STL100-1.OS.10.2.1.1925.SW.537
Then take it to the service center.

I have tried it.
The Wifi never turns ON. If I go to the Wifi section in settings, turn it ON and then go back.. it will revert to off.
So it never finds any wireless signal.
