For the first time, I am writing something that is not related to photography in my blog. This is because at last after a gap of a year or so, I managed to find out the method to install unsigned apps to my Nokia 5800 (V51.0.006).

Hahaha....what a big relief and I almost give up until a few hours ago (before I manage to resolve the problem and decided to blog about this..)

I believe there are more out there still confused on the steps to achieve it as there are many websites out there giving tips but most of it does not work.

First of all, I would like to give credits to (http://nokia5800.net/help-guide-signing-unsigned-apps-without-hacking-your-phone/) for providing the website to generate the .cer and .key files.

Ok, enuff talking and lets go straight to the topic.

STEP ONE : GETTING THE .CER AND .KEYFILES

1. Go to http://www.symbian-freeware.com/download-free-signer-for-symbian.html and download Freesigner application

2. Then go to http://andy.ehandysoft.com/devcert.php



2. Follow the steps provided in the website. (Note : it will take from 12-24 hours to generate the required .cer and .key. So be patient.)

3. After 12-24 hours return to the same website and enter the IMEI# again and this time, you will get a similar page as below. Click the link that I highlighted with the RED BOX.



4. Download the RAR file (something like 201008241843556.rar) to your favorite location. :P

5. Extract the file (again, to your favorite location) and you can see similar files as below.

STEP TWO : INSTALLING FREESIGNER

1. Connect your mobile phone to your computer and transfer Freesigner, .cer and. key.key file to a desired location.

2. Install Freesigner on your mobile phone. You might  be getting the below error : Expired Certificate.



3. To resolve the issue, I change the current year from 2010 to 2009 and reinstalled and Voila!

STEP THREE :  FREESIGNER SETUP

1.Now that we have installed Freesigner, launch the application and go to Settings.



2. Click on Self Sign Cert and then click on the "Back" button. This will allow you to choose the path that you have saved the .cer file. Once selected, repeat the same step for the KEY.key file under Self Sign Key

STEP FOUR : SIGNING THE APPLICATION WITH FREESIGNER

1. Now we are done with the settings and you can start signing applications now. Launch Freesigner again and click on Add Task > choose the drive the application is located and "Add" the application to be signed.

(Note : you can sign a few application by repeating Step 1 )



2. On the next option, select "Self Sign Sis" and OK. This will then sign the app within a few seconds and the signed application will be located on the same location of the original file.(The signed application name ends with Application_Name_signed.xxx)

STEP FIVE : INSTALLING THE SIGNED APPLICATION

1. Try installing the SIGNED application now and you will definately succeed!

2. This step worked for me, however I would not be able to guarantee that it will work for everyone. Do try and leave a comment so that someone would be able to help if I can't help you guys!

Thank you!
