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
CProfDriver_SISX.ldd
Installserver.exe
Secman v1.10.sis
X-plore v1.34

Download

Mirror Link


Easy steps to Hack/unlock your N73
1. Download the file and unzip to your pc.

2. Transfer the 4 files to your phone memory card.

3. Install Secman v1.10.sis. When the installation is done, look in the Applications folder on your phone, and find Secman. Open it and wait to load. Follow the instruction and it will auto reboot your phone.

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:
Menu>tools>configuration Or by just pressing 0

Please make sure the following option is tick:

Select Show Hidden files

Select Show Ram drives
Select Show system files/Folders

6. If All ready then continue! By using x-plore
Go to C:
