    also you can access the configuration, doing the following :
    nGo to Calculator application. Enter "(+30012012732+"
    nType: *#0011# to enter Service Mode
    nOnce in Service Mode, do the following:
    nTap the menu button and tap Back
    nTap the menu button again and select "Key Input" and enter an upper case Q and press OK
    nTap the menu button again and select "Key Input" and enter 4 zeroes (0000) and press OK
    nWait 5 to 15 seconds. You’ll see the Main Menu
    nChoose option [2]: UE SETTING & INFO
    nChoose option [1]: SETTING
    nthen [9] next page
    n[1] diag control
