change your mobile date to year 2006. and then try .it worked for me on n72..... hope it will work for you.

first you have to change your date (for example change the year to 2007) while u connect the use

You have to adjust the date to a year earlier and then try to install the app again. After the successful installation, don't forget to set the correct time and date. Also, on Apps settings, you have to select All in the app certificates.

you should set Online Certificate Check to "OFF" to rectify the issue.

You can set it OFF by doing the steps below:



1. Menu

2. Settings

3. Phone Settings

4. Applications

5. App. Manager

6. Set Online Certificate Check to "OFF"

7. "Software Installation" should also be set to "ALL"


another way is;

3. Phone Settings

4. Data Manager

5. Application Manager

6. Options

7. Settings

8. Set Online Certificate Check to "OFF"

After you have done the steps above, clear your phone's web browser's cache:

Hi,

Don't worry this is simple settings issue.

Note:Please download only E63 series Themes only.......not other phone themes...

To solve this problem follow the steps:

1)Go to Menu-> Tools-> Application Manager
2) Then press (options) button, select (settings)
3) Make sure <Software installation > is set to "All" and < Online certif.check > is set to "Off"

Some time you get certificate expire to solve this you have to change the date.This is to prevent the users from using expired application:
If you encounter Expired Certificate error during installation, please set your phone date to 03/03/2007 before installion of the theme .You can reset your phone date back after installation.
If still the problem persist Change the PC date also because it will get synchronized with your mobile and try different dates so that it will match the application date.(Reason is every application is valid for a period of time
example.from 03/03/2007 to 03/09/2007 so you have to give date between this.So try old dates usually some years back...

Please do rate the solution if the issue is resolved or post a comment for further assistance.


thank you for using fixya have a nice day:-)

Theme file like that is unsigned, which generally has a specific lifetime to be able installed on the phone. To fix this, change the phone date according to the date of theme still valid.
..
For example:
Open Menu > Settings > Find Date & Time. Set your Year to “2006′. Because some applications are certificated for 2005-2006. After setting your Year to 2006 install the application who gives certificate error. Finish your installation and you can set your current date back :)
..
Before it, make sure that you had check online certificate on the phone.
Go to "App. Mgr.", press "Options", press "Settings", make sure "Software installation" is set to "All", and "Online certif. check" is set to "Off".

whenever i install smartmovie player or other softwares in my n73 , it shows the error "expired certificate". plz help me ,
