My preinstalled calculator in nokia 5200 has been deleted how can i get it back??? i have even tried restored factory settings but it is not working

The inbuilt calculator should be in the organizer. It's kind of strange that the calculator is missing because you can't delete or move this application. Try a reset by typing *#7780# and the password is 12345. The other option is is firmware update using a PC Suite.

DEAR FRIEND,YOU WILL HAVE TO RELOAD YOUR PHONE WITH A FLASH FILE.

Hello thanks for using FixYa

2. Restore all — to reset all preference settings and delete all personal data, such as contacts, messages,

Select one of these based on your requirements and yeppeee! you are done. :)

if the 12345 is not working than you need to use data cable for restore setting

try 0000 or 1234

you can also use the a peper paking on a som card other wise change your monile huddy

only way to fix that is by resetting it with factory settings but it looks like youve already done that. so you might just have to live without it. give nokia a call, they can probably brew something up
