The procedure requires a PC with Windows XP or Vista, if Windows Vista you must give administrator permissions to the program, that you do so before you run, for this you do click with the right button on the pkey and you do click where it says run as an administrator, to leave displayed a poster of Windows, we give him to allow and ready.



How to change product code in 5800:


  1. Download and install Nokia Ovi Suite, click here to download. Once installed, you must connecting the phone cable at least once and select the PC Suite. This is installed in the system the drivers of the cable and telephone. Before moving to step 2 we must make sure that the mobile has to be able to correct connection with the pc mode ‘pc suite”.

  3. Make a copy of the contents of your phone. Copy applications, agenda, calendars, images, etc. The upgrade can be done without deleting the content of the phone previously, but sometimes there are errors with configurations of the previous version or with applications that had installed.
  4. Make a hard-reset, so you put 5800 without contacts, without applications, with the default configuration of all parameters, etc. To make the hard-reset writes: *#7370# and writes the security code, if you never has changed, which is expected by omission is: 12345 and click: Yes
