Application Certification in 3rd Edition S60 Phones
Category: Cellphone Application and Cellphone DIY -
You might have experienced failure in installing freeware applications with sis extension in 3rd editions S60 symbian phones (Nokia 3250, N71, N73, E0, E65, etc.), such as screenshot, ActiveFile, GNUBox, RotateMe, Fexplorer, and so on. This failure is indicated by the notification of “Certificate error. Contact the application supplier”
This reason of this failure is because the sis files you inject haven’t had the official certification from the developer (unsigned). As you know, 3rd editions S60 symbian phones have mandatory unsigning feature, meaning that this version of symbian has a security system which makes only have-been-signed application can be installed.
The examples of the uncertified applications are usually software in beta version, not the full one. Uncertified applications could also be in the forms of freeware applications. Though you can still wait until the signed version is released, the process often takes a long time. But if you have badly wanted to have the application installed in your phone, what should you do then?
To make your wish come true, what you need to do is a simple trick, self-signing the application. Don’t worry. Since the certification code comes from the developer producing the application, this action is considered legal.
The required tools are:
1. SignSIS files, which can be downloaded at http://d.turboupload.com/d/1639526/signsis_files.zip.html. You will get a zip file (489.34 kb) containing auto_signsis and signsis files. Extract them.
2. Account at www.symbiansigned.com. You are required to sign up as the member of this site.
3. DevCertRequest Tool, which can be downloaded at https://www.symbiansigned.com/DevCertRequest_30_10_2006_v2.0. You can check its update info at https://www.symbiansigned.com/app/page/overview/latestProductUpdates.
Steps of Certifying
a. Create a new folder in your PC. Put the unsigned SIS to be certified (in this example: screenshot_s60_3rd_v2.70_unsigned) and the two other files from signsis_files.zip into that folder.
b. Extract DevCertRequest you have downloaded, and then install it in your PC.
c. Run DevCertRequest Tool. You will be required to make a new file. Name it as you like, and choose the folder you have created as the output directory, for instance, tips.csr. It is recommended to name the file like the name of the application you are going to sign, such as screenshot_s60_3rd_v2.70_unsigned. For the next step, select ‘Open’ > “Next”.
d. In the statement ACS Pub ID Available, select ‘No’. At ‘Private Key File’, browse the folder you have created. Name it like the previous file, tips.key. Select ‘Open’.
e. Type “12345″ at Private key file password, and reconfirm it. Select ‘Next’.
f. Complete the available column. Make sure you do not leave the column with (*) in blank. Select ‘Next’.
g. In IMEI Editor, type the IMEI numbers of your phone to obtain the certificate. If you do not know your numbers, type *#06# when your phone’s screen is in standby mode.
h. Select all “Application Capabilities”, and select “Add”. Next, select ‘Next’.
i. For the final step in DevCertRequest Tool program, select ‘Finish’. In the folder you have created before, you will find four new files.
j. For the next step, go into www.symbiansigned.com and log in.
k. Select “My Symbian Signed” menu. Next, select ‘Developer Certificates’.
l. Select “Request” under the “Developer Certificates”. Then browse the CSR file in the folder you have created before.
m. Select that CSR file (click on ‘Open’) and ‘Send’. You will be taken to the download link of a new certificate (CER file). Download and save this certificate file in the same folder like before. Now, you already have all files required to sign your sis files.
n. Open auto_signsis file with MS Notepad.
o. Change the “xyz” character according to file extension in the folder. Save the batch file (‘save’, not ‘save as’). Then, exit.
Open your folder, and double click on auto_signsis file. Now you will get the new application certified, still in the same folder. Finally, install the application to your phone, and enjoy it.
Have a nice try!

I’ve followed all the steps, for some reason, when I double click the .bat file, I can see the screen starts working and then it says “bad decrypt” at the end, then nothing new gets created… have I done anything wrong? I checked again and again, is it possible that symbiansigned can’t verify my IEMI number?
