How To Sign Unsigned Files On A S60 3rd/5th Edition Device Itself

Following on from the previous tutorial which showed you how to get a developer certificate (to sign unsigned applications) quickly, is this guide which shows you how to sign it on the phone itself without the need of a computer.

This should especially be useful for people like me who own a Mac, for which there is no signing application, or for those who appreciate the convenience. I will be using a N97 to demonstrate the application, but the process remains exactly the same for any other 3rd Edition or 5th Edition device.

HOW TO SIGN UNSIGNED APPS ON YOUR S60 3rd/5th EDITION DEVICE LIKE E71 OR N97


REQUIRMENTS:

  • A S60 3rd Edition or 5th Edition device.
  • A freeware called ‘Free Signer’ which you can download here.

INITIAL SETUP:

  • Install the application on the phone memory or the memory card/inbuilt storage.
  • Open ‘Free Signer‘, select options and then Settings.

  • Next simply hit ‘Back’. You are now ready to sign unsigned applications on the phone itself. Please note that you will need to do the above only once.

SIGNING APPLICATIONS:

  • In order to sign a unsigned file present on the phone, click on ‘Add Task’ and navigate to where the application is located. Once you reach the file, hit ‘Options’ and select ‘Add’.

  • That’s it, your unsigned application will now be signed without you needing to use a computer. You will be able to find the signed file in the same location as the original application. A ‘_signed.sisx’ extension would have been added so that you can easily identify the file you can now install.

To sign another application you will only need to follow the steps under ‘Signing Applications’ and not have to do the ‘Initial Setup’ again.
