Hello: I'm from syria, a few days ago I have faced a problem after I updated my Xperia J ICS to JB,now my build number is 11.2.A.0.33.
Now i got Wifi problem,My wifi can not detect any network.
I did update Via Sony Update center,the only way to fix this is to downgrade to ICs.

I suggest that you try to repair the phone software using PC Companion..

Before repairing your device you may want to backup your information first. Check out this topic for more information on how to.
How to backup?

If the issue should still remain I think that this needs to be examined and fixed at a repair center. For more information about how to submit your phone for repair and where, contact your local support team.

I did all what you said (repair - backup) trying to connect to local support but my country (syria) isn't listed.

p.s.I bought the phone from saudi arabia (KSA)

jelly bean 11.2.A.0.33. really change my xperia j behaviour it becomes much better than before and you can feel the change directly after the update, you can feel it in screen ,battery,charging time, and the best is how pretty it becomes, but the wifi problem make me upset and turning back to ice cream sandwich again! I hope sony can solve this problem soon.
