You could try a software repair on the device using PC Companion.

1. Start PC Companion

2. Start Support Zone

3. Select Phone/Tablet Software Update

4. Select repair

Note that data will be removed from the handset, so make sure to back it up.

After update I am facing a problem at Wi-Fi connection. when I try to connect at Wi-Fi it shows Obtaining IP address....

Can any one help me to fix this problem...

Check your router channel number if it's on auto try to change this to for example channel 6

Also on your router check security settings as it may be blocking your phone
