5800 XM “Expired Certificate” error message
For people who own a Nokia 5800 XM, the error message of “Expired Certificate” when downloading applications onto the device will be mean you cannot load on new apps, which can be frustrating.
Firstly you should try to update the firmware on your phone by 1 of 3 ways.
- Using FOTA (Firmware Over The Air). Another thread of mine will explain this in detail. You can find it here.
- Downloading Nokia Software Updater(NSU) and connecting your 5800 to the computer using a data cable.
- Taking the handset to a Nokia Care point if you do not want to try the above 2 options.
**NOTE: Always be sure to make a back up of your personal details that are held on the phone as updating firmware will most likely delete any data left on the phone.
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.
- With the phone switched on, press the power button key once.
- Scroll down to and select “Remove E: Memory Card”.
- Select Yes to remove the memory card.
- Press OK and remove memory card from phone.
- Press the Dialler on the main screen.
- Type *#7370#
- Enter security code. Default is 12345 unless it has been changed.
- The phone will reset, wait for this to complete and power back on.
- Select your country and type in the correct time and date.
- Wait for the phone to complete its configurations, you may receive “My Nokia” or tutorial messages.
- Power off phone.
- Insert the memory card.
- Power on the phone.
- Wait for the phone to install any pre-loaded content from the memory card
- Phone is ready to install applications, without “Expired Certificate” error message.
I have done the above myself and downloaded the PDF reader from the “Download” application from within the handset and it installed with no error after these steps.
I hope this helps.
