If you tried to install my Nokia Symbian Themes or any Applications from this site and you got an ERROR message in your Nokia Mobile which says “Expired Certificate”:

Rating: +49



If you cannot install certain themes/ games/ applications, try doing this:

When installing my themes to your Nokia devices such as N95, N80, N91, N80 etc. out of the blue you just might see this message: “Expired certificate!”. This is simply because security measures within the Series 60 operating system only let you install themes which are less than six months old. ( …What a Shame!!)

But all is not lost, because all you have to do is you just have to move the date on your Nokia N Series/E Series back a year, install the theme, then change the date back to normal. (…Still Cant Follow me? …Alrighty then! Read on..). Below is a step by step instruction.

To change the date on your Nokia N Series or E Series, follow these instructions:

* Click on the Menu button, highlight Tools and click the centre selection key (the ‘OK’ key)

* Highlight Settings and click the OK key

* Highlight General and click the OK key

* Highlight Date and time and click the OK key

* Highlight the date and click the OK key

* Use the Right Navigation key to highlight the year. To change the year back one year, press the Down navigation key once.

* Press the Red “End” key to return to standby mode.

And Voila!! Now install your new theme and the chance it should be installed all smooth is 99.99% (…Unless you are one of those real unlucky guys who is just unlucky!).

If you still see the Expired certificate error, change the year back another year and try installing again. ( ..Trust me… It also works sometimes, just trust me!!)

When it’s installed successfully and you are all happy go lucky, REMEMBER to follow the instructions again, setting the year back to the present by highlighting the year and pressing the Up navigation key once (…this is to ensure that you are not late by one year the next day to wherever you might be going LMAO!! )

    Phone: Nokia N96
    Firmware: 11.101 (latest)

    Followed the above mentioned steps prior to installing Psiloc Connect….same thing over and over again: “Certificate Error”.

    Hi there,

    I am on N96, firmware 10.065. I downloaded and installed creatures of the deeps (ie. extracted archive to computer then double-clicked on the installer). Then, got message to continue installation from phone. Opened N-gage and it automatically began “preparing installation”. After a few moments it said “File is Corrupt, delete now?” then gave me two options, yes or no.

    After that, I have the creatures of the deep imagery there like a game available to play in my n-gage console, but it is greyed out. When i click it, it begins the preparing installation dialogue again then says it is corrupt.

    What do you suggest?

    Please email me…

    Kind regards,

  32. zuumus10

    Hi! Would this also work with a non nokia N series and E series phone? thnx…^_^

  33. bubble.tea

    To a reasonably n00b-a-licious programmer-type-person., I am thinking…wouldn’t it be easier, if you just updated the dates on your software? I guess, after a certain point you just have too many downloads to be updating them every six months. Ok ok., fair enough. Hmmm, what about an auto-date-modifier script perhaps?

    Would that satisfy the window security restriction?


    AWESOME layout for the website btw :). Lovin’ it!!
