First: OF COURSE it has to be one 3G / WiFi .... !
Well, the two suggested solutions work sometimes, sometimes they dont. But in every case, YOU HAVE TO WAIT AT LEAST 24 HOURS, somtimes 48 !!!
If nothing happens after 1-3 days AND you tried all the solutions you can find in this forums, the only thing is to do a hard reset.
I was one of them, nothing worked, NOTHING. i tried for weeks and was patient. So i figured out:
- FIRST Delete your phone from windowsphone.com
- AFTER that, do the hard reset.
Done
Deleting from windowsphone.com is the important action!!!
But anyway:
*** Which ever solution works for you, try it at a time your phone is normally TURNED ON, with active Internet connection (so lets say midday?...).***
Because if you reset your phone e.g. at 3pm, it will (or should) check exactly after 24 hours....so 3pm.
