How to Sign an App
Posted on 28. Jan, 2009 by geek in Applications | 35 comments
If you have got certificate for your mobile, now you can install any unsigned application on your mobile and then install it and you won’t receive any error. To learn how to get the certificate for your mobile, read this post.
If you mobile is hacked, then you don’t need any certificate or signing process, you can install any unsigned application or game on your mobile. For hacking the mobile, read this post.
After getting the certificate, you need two things, one is an app for siging, and there are many but you can download one from here and other is a key. You can download the key from the bottom of this post, named NoPass.zip
Now I am going to write step by step procedure.
1. Download the freesigner and install on your mobile.
2. Download the NoPass key.
3. Place the NoPass key (after extraction from zip folder) and your certificate on the E:/ drive on your mobile.
4. Place the application which you want to sign also on the E:/ (also called memory card) of your mobile.
5. Now open the freesigner application from your menu. Press OPTIONS and then select SETTINGS as shown in the screenshot below.

6. In the SETTINGS, under “Sign Cert” select your certificate from the E:/ or memory card. And under “Sign Key”, select your NoPass key from the E:/ or memory card as shown in the screenshot.

7. Now come back on the main screen of freesigner, and click ADD TASK. And then select the app which you placed on the memory card and click OPTIONS, and click ADD. As show in the screenshot, where I am going to select mConnection.sis.

8. After you click ADD, you will be presented three options as shown in the screenshot below and select “Sign Sis”

9. Now select options and press Go!
10. The app will be signed and placed on the E:/ or memory card.
11. Now install that application.
12. Now keep placed the certificate and key on E:/ and place another unsigned app on memory card and sign and install and go on.

@Ahmad, from where you got the certificate?? Try the other signer or try the signer which runs on windows.
@Reypgs

Hey geek,i need certificate for my nokia N95,my imei is 354835011955219
@Vaiko Joel… I have shared many sites from where you can get certs free within 24 hours.
same problem with Ahmad:
When ever i try to sign an application message is displayed, errors found in operation logs are write to C:\data\freesigner\freesigner.log, i have n85
when i use SignSis, for the key file i use NoPass.key or key.key from that certificate website? If i use key.key, it will say error load key file. If i use NoPass.key, then it will say error load Cert file. the certificate file i got from the website above u given. any help for that?
@Sam… use this software which runs on windows http://cer.s603rd.cn/template/signtools2.2.rar Keep your key, cert and unsigned app in a folder and then sign the app using this software. I will work more on signsis to know why it does not work, currently little busy.
@geek… thanks signtool2.2.rar work for me =]
