You can not Hard Reset an S40 device like Nokia X2-01. And, even if it was possible, it wipes all data from the Phone memory..so where is the question of getting the accidentally deleted things back ???
Just curious..How did you manage to delete ALL these things accidentally ?
Did you try re-installing the Firmware as suggested in one of the other threads by you ?
OK.. I asked because if normally if you delete one thing (e.g Games..) accidentally..you will not do the same with other things you have mentioned..
..and fine..get the Software reinstalled at Nokia Care and post the results.. Best of Luck..
