Certificate Error In mobile and it’s solution
Attention owners of Nokia E65 and other smartphones based on Series60 3rd Edition!
When trying to install themes downloaded from this site, you are most likely to get “Certificate Error” on your phone, and the theme will not be installed.
To get rid of this error, just complete the following three easy steps:
| Step 1: Go to Application Manager | |
![]() |
Find App.Mgr. in your main menu if you haven’t moved it somewhere else already. Then open it. |
| Step 2: Go to Options and choose Settings | |
![]() |
In Application manager press left soft button (Options). Choose Settings from the menu. |
| Step 3: Set parameter values as shown on the picture | |
![]() |
Set Software installation to All, and Online certif. check to Off |
Expired certificate error
In addition to the certificate error, you may also encounter the ‘expired certificate error’ which involves a slightly different work around. You’re more than likely to encounter this error at some point. It occurs because of the symbian security on the handset itself. Basically Symbian only allow a certificate to be valid for a maximum of 6 months. What this means, is when you try to install a theme older than 6 months, your phone will quit during installation and display ‘expired certificate error’. If you encounter Expired Certificate error during installation on to your Nokia phone, please set your mobile phone date back 1 year before you install your theme. You can set the date back after installation completes.
Method 2
Please go to Menu → Tools → App. Manager → Options → Settings → Software installation – and change it to “All”.
restart your phone and then try reinstalling the application

I have a big problem with my nokia N81. my phone had virus and I re-configured the factory setting by using the “*#7073#” method. Then after that I cannot install .sis file into phone. It always appeared “Expired Certificate”.
I’m really desperate cuase I need to install some important apps. If anyone has any idea let me know. I’ll be really appreciated.
