How to Fix Expired Certificate Error

I’m receiving a lot of comments and mails about this problem. Solving Expired Certificate error is very easy

Open Menu >Settings

In 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:)

    Thanks For Info…

    You can also use SISWare to see the exact validity period of a certificate or just resign it with your own certificate.

  16. 16 Nilanjan Das

    Its not working in my E61. After changing the year to 2006 the error message while installing is ” certificate may have expired and there is error in your date setting”. Also i ve not able to instal adobe reader as the .sis file is not supported. Tried with mobile signer but as the file is not getting copied am unable to load the sis file…also unable to download 3gp files as it is getting downloaded as text document…pls help, regards,

  17. 17 Arvic AUSTRALIA

    You can also try to change the month.
    I changed mine (N73 ME) into June 2007 and the expiry message did not appear anymore.

  18. 18 Gurkha SPAIN

    It works for my N95 8GB if I change to 2007 instead of 2006

  19. 19 Rusik UNITED STATES

    Just check the date of your file was modified, for example if it was 4/12/2006 change date in ur phone on 4/15/2006 and it will work!!!

  20. 20 WorldSense NORWAY

    for those who have N95 ,and if u have already a certificate and it expierd dont worry , sign your new application with it , and when you want to install it on mobile ,you can just go the the CLOCK and go to change the date back to same period your certificate was vaild. There you go , install your application with no problem.

  21. 21 mike

    works perfectly with my n93i. thanks. ive had this problem with my previous n80 and e61

  24. 24 Kim

    If me download turbo msn there are update error n say install base package first..

  25. 25 Sunny

    I have an N82 and was having the same problem. I called Nokia support to register my phone and also get some help with the discussed issue. I was told that registering the phone should fix the issue and it did. Interesting huh?!


    Same probs “Certificate error. Please contact etc etc…” on N95 8GB.
    Had probs with other progs similar. Tried various hacks but no use…
    Why do some progs not need certs and others do? Makes no sense…!

  27. 27 mohamed saleh

    works perfectly

    thank u

  28. 28 james PHILIPPINES

    ohh my gosh! it works for my n95…

    Thanks for the tip on Expired Certificate. It was very useful

  30. 30 Ivan

    HEY when I wanna install any .sis file on my mobile it says CERTIFICATE ERROR. My phone is sponsored By VODAFONE does this have anything to do with this ?


  31. 31 Murtaza OMAN

    Nice, but there is also another way around. .Go to “Settings” > “App. mgr.” or “Installations” > “App. mgr.” then Select “Option” > “Configuration” and Change “Software installation” from “Signed only” to “All”. Thats it. It is easy but beware only install softwares you’re sure about.

  32. 32 Zaheer SRI LANKA

    Thanks Rusik Its working perfectly in my N73 ME.This was big problem for me last few months.

  33. 33 maulin INDIA

    thaks dear its working on n95

  34. 34 pritesh mohan
  35. 35 subhash

    Works perfect.
    Did small analysis!!
    First I changed the date to XX.XX.2005. It didnt work. Changed the month. Again didnt work. (Thanks to James)Then I changed to year to 2007 and it worked!!!!. While installing, i saw the license information, and saw that the application is launched in 2006.

    Conclusion: I guess that most of these applications are launched in the market during 2007. So, whenever you are changing the date, see when is the application launched in the market and take the dates which are near to it.

  36. 36 prakash

    thanks, it worked great on N82

    how abt nokia E66, change date still cant’ install


    Best Way to do that is Go to “Settings” > “App. mgr.” or “Installations” > “App. mgr.” then Select “Option” > “Configuration” and Change “Software installation” from “Signed only” to “All”. Thats it. It is easy but beware only install softwares you’re sure about.

  85. 85 edward JORDAN

    i’ve 5800 xpressmusic. i’ve faced the certificate error many times, and i’ve tried working out on the date settings - the years (2005, 06, 07, 08, 09) and also have played the months (jan till dec) - but still it none of them worked. Then i’ve tried the *Go to “Settings” > “App. mgr.” or “Installations” > “App. mgr.” then Select “Option” > “Configuration” and Change “Software installation” from “Signed only” to “All”* yet nothing.

    i guess i’ve tried most of the obvious solution, i wonder what more can i get through.. by the way, i’ve even tried checking the details. sends out to who could ever fix this thing.


  86. 86 edward JORDAN

    just to let everybody know, i finally got it… the thing worked after resetting it to its basic settings. for those who couldnt make it work as i was sometime ago, just pull your SIM and Memory card off the phone, then reset the phone, keep its region as “Hong Kong,” there you have it… place both the cards in back to the phone. voila!!!

    things are really complicated, but if you need more of the COMPLI-answers, you gotta lot of forums to run to…

    Cheers everyone!!!

    one more thing, just an advice though, dont be afraid to crack your gadget, you’ll never know what happens next if you dont risk it. besides, that’s where the thrill of getting MODERN brains working! No offense, just a fact.. ;)

  87. 87 bassam

    guys i found the solution if u want to know what is year u must put
    tupe on your phone *#0000# then u can show the year of your phone then go to clock setting and change the date to the same phone date :)

  88. 88 jamdre19 UNITED STATES

    Format the Nokia 5800, E61i

    Access to touch keypad and enter *#7370# secret code (not so secret, anyway) to restore phone settings to factory default (even the user data and files are deleted).

    Next, you’re prompted to enter the Nokia phone lock code. The default is 12345, if this code hasn’t been changed by yourself or any one.

    Then, the phone restarts and you’ve to select the country region (just select your own country from the list, in this case), followed by request to enter current date and time.

    When the phone is ready, power it off again to re-insert the memory card (for highly safety measure, unless there are nothing important kept in the memory card, e.g. picture, music, documents, etc).

    As the phone is switched on again with memory card inserted, the “preparing memory card” message appears.

    Finally, I’m happy to be able install all my wanted Nokia 5800 programs and games without getting the “Expired Certificate” error message that says “Certificate may not yet be valid, is expired or phone’s date setting may be incorrect” :-)

    Go to the TOOLS.
    Then move to Menu >> Tools >> SETTINGS >> Applications >> APP Manager >> Software INSTALLATION.
    Now here you have to change here one setting which is “SIGNED ONLY” to “ALL”.

    Im using Nokia N 5230. i tried a lot the same option. but i can’t. Could anyone can help me?

  199. 199 Rahsek

    Hi all,

    Let me focus to all problems,

    Basically the application validity period is specified. Many phones frequently get this ”certificate error” frequently. I also had it on my nokia e90 communicator. Many of u have tried to change date n workrd for very few. For others the reasons may be:
    - your phone’s manufacture date is latest than that of application and dor this changed date shows the date related errors in phones. For this as some friends said check and try by making to phone’s manufacture date
    - may be due to some app certificate erors. For this the app signing by sis signer or other signing methods and installation may work.

    I dont think there is specific way to eliminate this error. So try these two ways. You might get lucky. For me 2nd method sometimes work.

    - the sure shot method may be hacking/cracking your device. This method is available in many blogs so google it and works for many/almost all other app as well
    I haven’t tried this one as i don’t want to get my stuff hacked.

    P.S. Go to hell with the administrator who don’t respont to such a critical field. You don’t deserve to be adminidtrator.

  200. 200 coolnessp INDIA

    This is how you can crack it. you need to do this only once. You never need to change your dates after this or even bother about certificate expiration or certificate errors while installing games or apps.,23866.0.html

    Als je geen installatie- of certificaatfouten meer wil hebben installeer dan gewoon drakkarious(mobile hack).
    Lees via internet via drakkariuos hacking de voorschriften en installeer alles wat je maar wilt,tis echt gemakkelijk.

  204. 204 Darrell

    It never worked for me. I tried all the methods, yet it didn’t work. Strange thing was, I self-signed the application with my own certificate that expires in 2013. Now’s the year 2010, yet when I try to install the application my Nokia E63 says “Expired Certificate”. Can anyone help me with this irritating problem?

    Use sisware to find date of expiry,then set the phone date before expiry.100% working

  209. 209 SMAr2wo

    For N95 8GB will not work. But is working with “hellocarbide”. Search on google this..and you will find some steps to eliminate the problem. Pay attention!! Do not make anymore firmware update (PC Suite update) on n95 8gb!!! 35.00.001 or above/beyond is a dummmy! You will have a lot of problems, including certificate error!
