E61i themes installation problem: Certificate Error & Expired Certificate

January 26, 2008

As much as I like themes to personalize my Nokia Eseries device they are also a cause for the vast majority of all questions I can see in Eseries forums. Maybe we have the same difficulties installing such feature. But to cater those who do not know yet how to fix the problem, here is the answer.

Even if  this have been covered extensively in the past I guess it is still an issue.

If you try to install a theme and see the above error message "Certificate Error. Contact the application supplier" You are trying to install an application that is not Symbian signed.

 

The solution is easy. Simply switch the setting in the Application Manager from "Signed only" to accept all - "Software Installation: All". You can find the application manager in the tools folder, then click on "Option" to bring up "Settings"

Another common issue is the "Expired Certificate" error. The certificate that the theme developer used may have expired. However, there is an even easier fix for this issue.

Simply set the date on your device back one year and then install the theme. After you successfully installed the theme don’t forget to set the time correctly on your device.

I do hope this helps you concerning E61i theme installation problem.

for “’certificate expired or date stored is invalid’’ problem. you simply need to try different date. usually within 2 yrs from today(March 4 2008)
anyway, just try different date.
