go to your phones date and make it one or two or three or more years back and then install it..... now it will not show expired certificate....... vote for me if you are helped

change your fone date your problem will solve

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 can not use java in n73

expired certificate is an easy error (the easiest at all)
just change the date of your phone backwards
i mean change 2010 to 2009 then try installing
if it appeared again
change 2009 to 2008 and try again
and so on till you reach the proper year
after installing get ur phone date right the program will not be affected

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:-)

chage the date to past for months and try.if the problem exists you have to buy new Rotateme copy.....else you have to hack your phone which is dangerous

Certificate expired is when the theme has expired, best thing to do is look at the date of the theme before you download it so you won't have this problem.
Try mobile9 website they show the expire dates

Good luck

You are downloading a lonely cat application. That is wrong.You download a BinPdA application then smart movie install in your device.
