how to install un-signed S60 3rd games or applications

sometimes we got error messages about security and incompatibility during installation of S60 3rd games or software, one reason is the sis or sisx format games or software we downloaded were un-signed version, due to platform security restrictions, we need to sign the sis or sisx files with a proper certificate (DevCert, etc) to be able to install it and run it . this is how:

  1. Go to and register a new account
    (be careful: you must insert your correct IMEI in the registration form!)

  2. Go to My Simbian Signed--> Developer Certificates and download DevCertRequest tool.
    Direct link: DevCertRequest_30_10_2006_v2.0.exe

  3. Install the application and download this private keyfile (Mycert.key).
    Symbian Signed.rar,

  4. It's time to create the certification request: open the DevCertRequest application you just installed and fill in the fields like this:

    Use the key you just downloaded.
    Private keyfile password: 31536u2

  5. Go ahead to next steps and follow examples shown below:

  6. Insert your IMEI no. and add all application capabilities:

  7. Click on finish and your Certificate Request will be created.
    You can find this file in the folder C:\Documents and Settings\(Your UserName)

  8. Go back to Symbian Signed website and go to My Symbian Signed --> Developer Certificates --> Request. direct link

    and upload the Certificate Request file you just created.

  9. Go to My Symbian Signed --> Developer Certificates --> My DevCert
    direct link.

    and download your certificate!

  10. Create a folder and place in TombRaiderLegend.sisx, the certificate you downloaded from Symbian Signed website, Private Keyfile (Mycert.key) and signsis.exe (you can find it in the archive attached above)

  11. Open DOS shell (Start-->Run-->cmd), browse to the folder you just created and type in this command:

    signsis TombRaiderLegend.sisx TombRaiderLegend_signed.sisx xxx.cer Mycert.key 31536u2

    (xxx.cer is the certificate you created, change it with yours)

  12. You're done! This will create a new file called TombRaiderLegend_signed.sisx (or whatever you want, just change the filename), install it and enjoy this great game!

here is the signing process:

in this example, you'll install : TOMB RAIDER: LEGEND mobile:
