Select Device updates and at the top of the Device updates page that appears, you'll see which OS version is currently installed on your Nokia C5-03. At the time of writing the latest version is V10.0.024, which replaced V10.0.031.
You can update your software in one of two ways – either directly over the air or via a software utility on your computer.
To update your Nokia C5-03 directly, tap on Options from the Device updates page you're already in, then choose Check for updates. Your Nokia C5-03 will then connect to Nokia's servers and see if there's a newer version of your OS available. If so it will ask if you wish to download. Tap Accept, and the file download will begin.
Once the update has been downloaded, you'll be requested to back up your data, as the update process will otherwise clear your phone's internal memory of any files you've saved there. Tap Accept, then you'll see a warning that your phone will be unavailable for a few minutes while the update installs. Agree to this and your Nokia C5-03 will start installing the update.
That'll take a few minutes, but the phone runs through the process itself without requiring your input. Eventually your Nokia C5-03 will restart and show you a message that the update is complete, and that's it – you're done!
If you're using a PC, you'll need the Nokia Software Updater (NSU), which can be downloaded directly from Nokia.
Connect up your Nokia C5-03 via the supplied USB cable or via Bluetooth, then fire up your NSU and follow the on-screen prompts once you've clicked Start. The software will locate your Nokia C5-03 and identify any updates available. To download, place a tick to agree that you've read the terms, then click on Install.
