A SF Forum member has released a new utility for Nokia S60 3rd Edition mobile device called ROMPatcher. This tool alows you to update the non-editable Flash ROM of your S60 smartphone with patches. ROMPatcher utilizes a technique that maps the ROM into the RAM and then modifies it due to which any changes made to it are stored only temporarily until the mobile device is rebooted. Also, as a result of this, no permanent damage is possible to the phone.

Currently two patches are available that utilize this functionality:


Nokia ROMPatcher: Flash & Edit your Nokia S60 3rd Edition ROM Temporarily

+ One, to enable hidden menus - link
+ Two, change the Swipolicy Path to allow installing unsigned applications - link

ROMPatcher opens up endless possibilities for modifications to your mobile phone, which were, up until now, not available.

Instructions:
———————
Nokia ROMPatcher

1. Download and Install AppTRK to your mobile phone’s main memory. Make sure Nokia PC Suite is not running on the desktop. Now connect your device to your PC using the USB cable in PC Suite mode. By default AppTRK starts in Bluetooth mode, cancel it. Then go to Options->Settings, change the connection mode to USB and hit Connect.

2. Once connected, find the COM port number of your USB connection from Windows device manager

3. Change the CheckAddr value in RPInstaller.ini to your Symbian platform version [For Symbian 9.1 the address is 60000148 while for Symbian 9.2, it is C0000148]

4. Now, on the computer, run RPInstaller.exe and enter the COM port number that you found in step 2. Do not select the “Patch Caps only” option. Click on Install.

5. If no errors occured, you will find a new application ROMPatcher in your phone’s Applications folder.

6. Cclose the RPinstaller.exe on the desktop. Exit from the AppTRK software on your phone and then disconnect the cable. Create a folder called Patches on your phone (E:\Patches). Now you can place any patch in this folder which will then be visible in the ROMPatcher software on your mobile phone from where it can be enabled/disabled.
