        i’ve updated to this firmware but i am unable to use online chatting apps like whatsapp, nimbuzz, etc n even youtube is not responding over my data connection. but everything is fine when connected through wifi. do you have any idea to solve this problem???

        • Vishnu says:

          Your APN is correct ? IT is connected to network data ? ask your network operator to send you the new settings ! :)

        • Bassam says:

          when you updated your phone , that means you have erased all data on your phone including your access points that your device using to access to the internet , so to solve this problem you have to go to setting>mobile networks>access points : and then create a new access point for using data connection

    I’ve just update the OS of my S2 to the Jelly Bean and the TW keeps coming over and over. I can’t even try to delete the widget that might probably be causing this issue. The time lapse between the message in the screen and the actual stop of the TW is less than 3 seconds. Thing is that this is getting very annoying, specially when I’m not even able to fix it through the mobile per se. Any suggestions on what to do?

    Thanks in advance for your assistance!!!

      You know your Original IMEI ? Then there is an easy way to restore it >> go to Xda-developers browser SGS2 Android development and search forum .
