Hack Nokia N73 to install unsigned apps (solve certificate error)

Ok, first of all, you must know why you need to hack your symbian phone.
Had you ever experience getting “certificate error” when trying to install software or game on your symbian phone? The “certificate error” is blocking you from installing all those great applications and games which will greatly enhance your symbian phone experiences. Without 3rd party applications, symbian phone is nothing more than an ordinary phone.
Hacking your phone is quite safe nowadays and you can do it in just few minutes.
The following tutorial is 100% working with Nokia N73 [4.0839.42.2.1] tested by myself.
First you need 4 files
Secman v1.10.sis

X-plore v1.34

4. Open it again and click on “Install Root Certificate”. After that now Select turn platform security off.

5. Install X-plore v1.34 . Open X-plore. First start to configuration of xplore which can be found on:

    • N73 is an old smartphone. It does not satisfy the minimum requirements to run whatsapp. You’ll not be able to run Whatsapp by any way on your N73. My suggestion is to buy a new smartphone or feature phone which supports Whatsapp.

    • Please follow the steps given in the post and you should be able to install all applications on your phone. The other way round is to change the year to anything between 2010 to 2014 and you should be able to install the application. Hope this helps! Please let us know how you fare with the issue.
      Thank you.
