How to Get Your Certificate & Key File Instantly for Signing Apps
In this tutorial I will show you 2 different ways to acquire the certificate and key files for your Nokia smartphones easily. This tutorial is mainly for those who have never signed any application before and are constantly facing errors during their installation of unsigned applications, games and themes. The common errors that are being faced by thousands of Symbian owners worldwide are “Certificate Expired“, “Unable to Install a Protected Application from an Untrusted Supplier” and “Restricted by Certificate Type“.
To Hack your Nokia properly you will have to have a developer Certificate and Key file for your Nokia device. The Certificate and Key File are tied to your specific IMEI number of the phone which is a security measure and that is what we will try to bypass.
The previous process of acquiring Certificate and Key file was only successful manually (Manual Method Tutorial – Not Recommended) and it was hell difficult to actually get your certificate and keyfile. But hold on, it gets much better starting from today. Here are 2 simple, quick and efficient ways to get your IMEI specific Dev Certificate (.CSR file) and Keyfile (.KEY file).
The first process is absolutely magnificent, moderately easy and can have you get your certificate and key within 2-3 minutes at best. There is a second method (manual method) which is super easy and also moderately fast and you are sure to get your certificate and key file within 24 to 48 hours.
Process 1:
Get your Certificate Automatically from your Phone by installing XSteveDore Express – a multipurpose certificate management application for S60!
What is XSteveDore?
XSteveDore Express is a new application from the guys at OPDA and it lets you check, acquire and update your certificate and key file straight from your device. The application is in Chinese and even though there is an unofficial English version available – I am going to show you how to do it easily with the official Chinese version as that version is available as a Signed Sis File. It is really easy so don’t be scared even though it is in Chinese.
However, note this cautiously, you will have to request, acquire and download the certificate and key file within the first 2 hours of the installation. After 2 hours, this application is useless in terms of obtaining certificate and key file.
Step 1 – Download and install the signed version of the application on your Nokia device. Download and Install SignSIS for signing any apps easily from your laptop or PC. Both these files are included in the download below:
Step 2 – After the installation is over, browse to your phone menu and enter into the folder “My Own” as shown below.
Step 3 – Open the Application and browse on to the last item on the screen!
Step 4 (Optional) – Set up your Certificate and Key File Save Location. The default set up for this stores the Certificate and Key File on to your phone memory but I recommend you to change that to your memory card as this will allow you to have a sure access to them.
Step 5 (Mandatory) – Click on to the “2nd last” item (the icon left to the last icon) of the application and you will see that you are being shown a pop up screen. Simply click the Left OK button of your phone, the application will automatically download the Certificate and Key file and ask you to name the file so that it can save on the location you specified . You can give any name you want.
Note: After you press the Left Ok button the application will ask for the Access Point to use when connecting to the server to acquire the Certificate and Key File. You must have GPRS/WAP/Edge/3G activated to successfully download and save the Cer and Key file. The process takes place in the background, takes around 3 mins to 5 mins in average.
Step 6 – This is the last step of the process and is simply a logical step. Open X-Plore or File Explorer or Connect your Phone in PcSuite Mode and browse into your device. If you did take step 4 and saved the two files on your memory card rather than the phone memory then browse into your memory card and locate the folder “MyCert” and you will find your Certificate and Key File within that folder. Make 2 copies of the “MyCert” folder and put 1 copy of the folder as a back up (optional but recommended for safekeeping) somewhere inside your phone or PC and transfer the other Copy of the folder on your Computer (anywhere you like).
Step 7 – Connect your phone to your PC or Laptop using Nokia PcSuite. You already have your Certificate and Key file located on your memory card and all you need is to get your hands on them.
Step 8 – Run SisSigner 2.2 from your PC and Browse to the Unsigned SIS File on the first Field, Browse to the Dev Cert File (the one you just copied from your phone) on the second field and Browse to the Key File you just downloaded. Then Click Sign Sis to successfully sign the application and install it on your phone! Yes – You Are Done!
Conclusion & Remarks: This is by far the fastest and easiest method available to acquire your Certificate and Key File for signing your unsigned Nokia Apps, Games and Themes. Get it now and remember – you must finish requesting the Certificate and Key File within the FIRST 2 Hours after your installation of XSteveDore Express.
Process 2:
The second process through which you can get your IMEI specific dev Certificate and Key File easily is by registering with any one of the 2 sites: Site 1 and Site 2. Both the listed sites are in English so it should not really be a problem for a regular web junkie to complete registration and getting your signing certificate and key files. This process however is very lengthy compared to the process I mentioned above. On an average getting your Certificate and Key File from either of them will take you around and at least 24 hours to 48 hours (or more).
Still, to make things really easy for you here is a step by step guide I prepared just for you – my good friends and loyal subscribers & visitors! In this guide I will be using Site 1 as the example site. Site 2 works the same way compared to Site 1 so one guide should do it even for the newest of newbies.
Step 1: Simply click on any one of the 2 links of the sites I specified. For this guide I am using Site 1 as an example like I told you earlier. After clicking you should be taken to a page for free registration. Here is an image with pointers on what and how to fill up the vacant forms.
Step 2: After filling up the registration form as shown above you will have to submit your registration application. This will show you the message “Registered Successfully” and forward you to the main page. You will now have to click the top right Login Button and fill the blank fields with your registration info as shown below:
Step 3: After you successfully fill out the Login Form with the username and password and have clicked the Login button you will be taken to the back-end of your account. While you are logged in and browsing the back-end of your account you will see a button which allows you to apply for a free Certificate and Key for your IMEI. Now click on that “Apply Certificate” button as shown on the image below.
Step 4: After you click on the orange “Apply Cer” button you will be taken to another blank form where you will have to fill up the info required for acquiring your certificate. It will ask for your Symbian device’s IMEI number, Phone’s maker and Model Number and for your remark. The remark field is simply an extra field so that you can tag this request and write anything relevant that you want to include. You can find your IMEI number by pressing the following combination on your phone’s keypad. The combination to find your IMEI number is: *#06#
Step 5 – After you have submitted your request to acquire your very own Certificate and Key file as shown in step 4, all you have to do is wait for 24 hours to 48 hours (or maybe even 72 hours) and check back to download your generated Certificate and Key. The time taken to have your files ready usually takes a day on average but it can take much longer.
Step 6 – To find out if your files are ready you will have to sign in again on the site. To do this you will have to click on the Login menu as shown below. Once you are logged in simply click on the”My Certificate” menu as shown on the image below. If your files are ready then the “State” message under the “My Certificate” menu will be shown as Normal. If it is anything else but Normal then you will again have to check back after 24 hours or so.
Step 7 – Once your State Message is shown as “Normal” as shown on the image above, it means your Cer file and Key file are ready to be downloaded. All there is left to do is to simply click on the .Cer file once and click on the .Key File once. They are located under the “Operate” header of the table shown below. These 2 files are what you need to Sign your Unsigned Applications, Games or Themes. These 2 files will also eliminate error messages such as “Certificate Expired” or “Unable to Install Protected Application from Unprotected Supplier” on your Symbian device. Once you have the 2 files, click on the “Log Out” link to safely return to our blog!
Conclusion & Remarks – As you can see this process is dead easy and with this tutorial in your bookmarks mean that you will never get lost at any point in time. I really hope that this tutorial and reference guide will serve all your Certificate and Key Files requirements that you sometime face when trying to install our featured applications, games or themes.

I’m still confusing, what should i do with the cer and key file. I have downloaded the freesigner sisx cz i want to sign helloox 2 but, it still could not install. Help me please, thank’s before.
hey bro.thanks a lot for this info.i already had my .cer and .key files…but i didnt know how will i use this..there’s no instruction after ive downloaded it..Am i going to put it already to my phone?
Hiya bro… that is up to you. You can choose to keep them on your mobile if you are usually downloading files from your mobile through GPRS.
However, my recommendation is this:
After you have downloaded the key file and certificate file you can make a copy of these 2 files and keep one copy of those 2 files (cer n key) on your computer and keep the other copy of the two files (cer n key) on your mobile.
The reason for keeping the files on your mobile and on your computer is so that you can sign any unsigned application or unsigned games easily from both the mobile phone and the computer.
To sign any apps/games/themes etc you will simply need any 1 of the 3 signer files I have included in the download.
Within the Signer folder you will notice that there are 2 .exe and 1 .sisx (already signed) file. The EXE files are for your computer whereas the SISX file is for mobile. All 3 of them are Signers – 2 of them are Signers from PC and the other is a Signer App for Mobile.
When signing files from your PC choose ANY ONE of the 2 EXE files (whichever you feel comfy with). Both the exe files are standalone programs so you are not required to install them – Simply Click to Open and Sign!
If you want to sign apps/games directly on your mobile phone then you will need to Install the SISX (already signed) file on your mobile device. The SISX file is a simple application that acts in the same way the EXE files does – only difference is that it does the Signing from your mobile phone instead of the PC.
