If you’re Nokia 5800 XpressMusic owners and you often get the error message like “Expired Certificate” when you downloading application onto your handset, i have found great solution for you to solve this problem.

Update the firmware of your Nokia 5800, you can choose one of the three option below to get the latest firmware. Backup all your personal details and datas first before upgrading your firmware.

1. Using FOTA (Firmware Over The Air). Another thread of mine will explain this in detail. You can find it here.
2. Downloading Nokia Software Updater(NSU) and connecting your 5800 to the computer using a data cable.
3. Taking the handset to a Nokia Care point if you do not want to try the above 2 options.

If you have used FOTA or NSU to update your firmware, or there is no new update available then doing the following will work and will allow you to install new applications without the expired certificate error message.

1. With the phone switched on, press the power button key once.
2. Scroll down to and select “Remove E: Memory Card”.
3. Select Yes to remove the memory card.
4. Press OK and remove memory card from phone.
5. Press the Dialler on the main screen.
6. Type *#7370#
7. Enter security code. Default is 12345 unless it has been changed.
8. The phone will reset, wait for this to complete and power back on.
9. Select your country and type in the correct time and date.
10. Wait for the phone to complete its configurations, you may receive “My Nokia” or tutorial messages.
11. Power off phone.
12. Insert the memory card.
13. Power on the phone.
14. Wait for the phone to install any pre-loaded content from the memory card
15. Phone is ready to install applications, without “Expired Certificate” error message.
