How to Get Your Certificate & Key File Instantly for Signing Apps

In this tutorial I will show you 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?

XSteveDor Signer

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.

After Installation - Signing

Step 3 – Open the Application and browse on to the last item on the screen!

Signing - Launch The Last Item

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.

Certificate and Key File Screen - Save It and Proceed.

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).

All the Steps shown on this particular image are Automated.

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.

Browse to Nokia Phone Browser

Browse to the Folder where the Cer and Key is saved using Nokia PcSuite or X-Plore
