STEPS TO HACK NOKIA S60 PHONE (src)

• Install freeware X-plore, a file manager from Lonely Cat Games. Run X-Plore, press 0 and check first 4 boxes. Don’t exit.
• Install and run HelloCarbide by FCA00000 (select Options -> Menu1).
• Switch to X-plore and check if you can see the contents of C:/sys/. If you can, then you are halfway done. If not, try step 2 again.
• Download CapsOnOff.rar by FCA00000.
• Copy CProfDriver_SISX.ldd from RAR downloaded above into C:\sys\bin of your phone. You can do this with X-Plore.
• Install CapsOn.sisx and CapsOff.sisx. Run CapsOff application to turn on the hack.
• Download SIS installer mod for Symbian 9.2 and copy installserver.exe file to c:\sys\bin\ so you can install unsigned applications
• Install ROMPatcher by Zorn.
• Whenever you need to install an unsigned application or patch your phone, just run the CapsOff application first. CapsOn brings it back to normal state.

CapsOn will not stop you from being able to install unsigned apps with this method. When using this, there’s no way to turn off the ability to install unsigned apps without removing installserver.exe. CapsOn and CapsOff is just for activating or DEactivating the access to the system files. no matter if you have them activated, you’ll always be able to install unsigned apps.

The SIS installer mod actually contains the installserver.exe. If this file is placed in C:/sys/bin, you’re able to install unsigned applications.

ROMPatcher is the Programm that let’s you enable/disable the security measures (like Caps On/Off), but also let’s you apply some handy little Patches, which you can also find at the Symbian Freak Forum Section!

Hacking a phone wont affect the ability of Upgrading firmware.
