From the original website:

Phones that run Symbian S60 (Nokia) and Symbian UIQ (Sony Ericsson) are like Fort Knox: they won't let you see all the interesting stuff in the system folders, and you can't install Symbian programs unless they've passed the censors at Symbian Signed. Even the capabilities of signed programs are limited to what the powers that be at Symbian HQ allow them to do. And Open Signed Online takes forever, if it works at all.

Symbian won't even let you change program icons or let you switch off that annoying noise that your camera makes every time you shoot a picture.

Even worse, you can't even access the files and folders that contain your messages and your calendar entries on your phone, which means that the horrible piece of bloatware called PC Suite is the only way to back up your messages and calendar.

The draconian restrictions of Symbian are like not having the keys of your own house.

But Symbian has been hacked : ) With a few modifications you can give yourself full access to your phone's system folders, install programs without having to beg Symbian Signed for the keys to your phone, change icons and menus, switch off the camera shutter sound, and make backup copies whenever and whereever you want without having to connect your phone to a computer that runs PC Suite. Now Mac and Linux users can finally back up their data!

Tame Symbian and tell your phone what to do instead of the other way 'round.

With a few modifications you can give yourself full access to your phone's system folders, install programs without having to beg Symbian Signed for the keys to your phone, change icons and menus, switch off the camera shutter sound, and more.

This hack doesn't make any permanent changes to your phone, it only modifies the RAM. If you restart your phone, the hack is switched off until you start it again.

To hack Symbian so that you tell your phone what to do (instead of the other way 'round), read all the steps below, then follow them in exactly this order:


  
1. Back up your phone memory. The easiest way is to open the data manager in your phone's settings folder, click on "memory," and then select "back up phone memory" in the options menu. Save a copy of the backup on your computer.
 
2. Make sure you have a file browser installed on your phone before proceeding. Make sure only your file browser is running, and nothing else.

The built-in Symbian browser will NOT work, so use a program like X-Plore. The free, unregistered version will do.
  
3. Download HelloCarbide, installserver.exe, and ROMPatcher. They're all bundled in a convenient all-in-one package.

Extract the zip archive and copy the three files to the memory card of your phone.

Do NOT open any of the programs yet.
  
4. Close all programs that may be running on your phone.

Start your file browser (the one from step 2) and try to open c:\sys on your phone. It should not work, because you don't have the right permissions yet.

Do NOT close your file browser. It needs to stay open before you start the next step.
  
5. Run HelloCarbide.

Go to options, then to menu1.

When HelloCarbide has done its job, it will crash. Don't worry, that's normal. Even with HelloCarbide crashed you'll have access to the system folders.
  
6. Use the file manager (still open from step 4, remember?) to copy installserver.exe into the c:\sys\bin\ folder of your phone. This allows you to install unsigned apps.
 
7. Restart your phone.
  
8. Install ROMPatcher.sisx and enjoy all the freedom that ROMPatcher gives you.
  
9. Leave installserver.exe in c:\sys\bin\ if you want 24/7 freedom to install unsigned programs, or delete installserver.exe if you want to play it safe and use ROMPatcher to enable installation of unsigned apps when needed.

Or sign your .sis files with a computer based or in phone signing method (see below for details).
  
10. If everything worked OK, now you have a program called ROMPatcher on your phone to toggle restrictions on and off.

Restarting your phone switches the standard restrictions back on, but you can launch ROMPatcher on your phone to set it free again.


Download the Hellocarbide package here:

Now you can extend the capabilities of your phone with ROMPatcher plugins...examples are:

- enable hidden menus
- install unsigned .sis files
- stop Java apps from asking for permissions over and over again.
