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

Posted January 25, 2010 by Chaos Inc. in Explore

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?

X Stevedore Signer

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:


Download All in One Signing Tools

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

After Installation – Signing

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

Launch the Last Icon

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.

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).

These Steps are Entirely Optional

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 Nokia Phone Browser

Browse to the Cer and Key

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

Dev Certificate and Key File

Your Dev Certificate and Key File!

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.

Symbian Signing!

Symbian Signing!

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.

Symbian Signing Guide 2 - Step 1

Symbian Signing Guide 2 – Step 1

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:

Symbian Signing Guide 2 – Step 2 (Click the Picture to view a Better Version of the Picture above)

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.

Symbian Signing Guide 2 - Step 3

Symbian Signing Guide 2 – Step 3

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#

Symbian Signing Guide 2 - Step 4

Symbian Signing Guide 2 – Step 4

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.

Symbian Signing Guide 2 - Step 5

Symbian Signing Guide 2 – Step 5

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.

Symbian Signing Guide 2 - Step 6

Symbian Signing Guide 2 – Step 6

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.

    Hi !
    1st method didn’t work for me cuz I couldn’t instal the app cuz of a missing certs XD
    and as many of you guys probably noticed both websites are dead so here is a quick tip for ya.

    I’m using Nokia E51 (s60 3rd) and there is such thing as application manager, it is a stock app provided by nokia. Launch it and go to settings and follow this:

    Options > Settings and set “Online Certificate check” = Off and Software Installation = All.

    Surprisingly (or not) It solved my missing cert errors 😀

  84. aman

    I will give you cery & key instantly. Please let me know how to sign application by it.

  85. Xanderone

    This certificate thingy is not working. Tried the xstevedore, it installed but on connecting to get the cer, it gives an error “exclamation” mark response.

    Going over to OPDA to obtain cert after registeration is not easy either. It keeps asking you for login details even after it must have acknowledged and welcome you as a member already logged in. Even then, this the second week, the certificate is still being produced.

    Chaos Inc., show us a way outta this dilemma please.

  86. Bsienn

    Both methods not working,not the software cert&key and you all know about opda

  87. mahesh

    please tell me what to do

  88. nrg9x

    opda is not giving keys no more , all sites associated to obtaining your CERT & KEY have been blocked . hacking the phone is a option but it has its side effects too so b careful !

  117. tinashe

    according to your instructions I am meant to run SisSigner 2.2 from my pc. Is this particular program part of the initial download coz I went through it but I cant find a signing software with that particular file name. I have located one with the file name ‘signer’ which is located in a folder ‘signer 1 – PC’ then there’s the other one named ‘signtools2.2’ which is located in the folder ‘signer 2 – PC’…

    …and what’s the ‘freeSigner’ application for? Can I use this to sign applications directly from my mobile phone?

  118. Ibro

    I’m using n95 8g & I try downloading SignSIS on my phone but its giving me certificate error Tell me what should i do about it. I need to download themes and lots on my phone. Help! Help!! Help!!!

    Dear colleage,
    Thanks for your help in getting out of difficulties related with certificates.
    I just downloaded the Cer. and key file.
    However, now my question is how to get further with the downloaded files?
    The Cer.file I could install at my computer.
    However, when I opened the keyfile ther came a question where registering this file? Could you give me an operationsguide how to apply the two downloaded cer. and keyfiles in order that you can work with them?
    Kind regards, I’m waiting for your answers,

      “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!”

    This link shows the stuff in english.

    Tried it many times( within the 2 hour frame), however the access point never gets established. The access points work fine otherwise for sure.

    It just shows the access point wheel icons grinding and the net connection never gets established, so i guess it never gets the certs.

    Anyway, Thanks.

    Anyone knows if this first process is still operational ?

    Will try option 2.

  133. Pretty confusing .

    There are a few more steps of chinese screens missing from the screen shots !

    Thanks for the effort though, must have helped many , I am sure.

  156. ubagu david

    i need my developer certificate and key,so how do i do that

  157. is there any certificate for my nokia c5 available. Process 1 wont works,shows error.

  158. mka

    Hi – I followed your directions without problems until step 5 of Process 1. When I click on the 2nd icon from last, then click on the left button, I get 4 items in a list: the 2nd says (cer) and the 3rd says (key). my xpressmusic 5800 only has an Options tab and a Back tab at the bottom. You say that the Certificate and Key should automatically download, does this mean I just press Back? When I go into the memory card I don’t see a new folder titled ‘MyCert’ (It’s also not on the phone memory because I followed the previous step). I do have a ‘AMDownloads’ folder however, but it’s empty.

    What am I doing wrong?

    Many thanks.

  159. me

    grate works fine!

  160. dan

  163. Chandra

    Hi. While installing XSteveDor, it shows certificate error….. Waste of my time…

  164. romeo1231

    As I know the cer and key file gives only certain permissions to an application. For example some applications like rompatcher and modo cannot be installed by signing with this certificates it will give error saying ‘required application acess not granted’ and for not facing that type of error hacking is recomended.

  165. Aamir

    can someone pls tell me that if we’re getting cer+key by following above procedure, then what’s the need of “HelloX2” and Rompatcher, as i found these to be very crucial on other websites?????

    • That means you have exceeded the number of times you can request a certificate/key. This also usually means that you have the key files and certificates already. So connect your phone to the Nokia pcsuite pc browser and locate your cert/key.

  193. amelcruise

    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.
