Nokia 5233|5230|5228|5232 : V51.1.002 Firmware Update with Changelogs
It’s another official firmware update OTA (Over The Air) for Nokia 5233, 5228 and 5232 Phones. The software version is V51.1.002
The previous firmware version was V50.1.001 which gave a smooth UI to the phones along with animated smileys and a powerful Nokia Browser.
The update can be downloaded via Nokia Software Updater Application or via FOTA by dialing *#0000# and then choosing “Check for updates” from the Option Menu.
Or you can update your phone via Nokia Suite by connecting with USB to your PC. But this will make the update into a larger size as it will include all the core files for the update. There is no difference between updating via FOTA or PC, just that through phone only the software update will be installed which is of small size (core files are previously installed) but through PC the entire firmware along with the core files will be downloaded and updated again which will make the phone a new one 
And don’t worry, it won’t format your phone so you wont loose any data. But as nobody can give a guarantee, it’s always to be in a safer side so backup your data before updating
