This post is related to my previous post on bypassing Symbian Signed for Nokia S60 FP1 platform. The drawback with this method is that it is not so intuitive and carries the risk of bricking the mobile device.

With the new Open Signed process (GenialSIS), signing applications is not so inconvinient. However, you still don’t get access to system files and folders in the C: drive.

A new hack has been developed with the help of AppTRK, available in Carbide Pro, a debugging software that can monitor data streams transferred between the mobile phone and computer via Bluetooth or USB. This hack works only on Symbian 9.2 platform and gives All Files access to any software, applications and programs, just like the previous method.

Here is the tutorial for hacking Symbian 9.2 on Nokia S60 from Finest Fones blog:

1) Download and install the pre-requisites such as ActivePython, PySerial, AppTRK and HackPerms on your desktop PC with the exclusion of AppTrk which needs to be installed on the S60 mobile device.

2) Connect your S60 phone using PC Suite in USB mode

3) Open Device Manager on your PC (Start—>Run—>devmgmt.msc) and under the Ports (COM & LPT) column, look for your phone’s port number.

4) Install AppTrk on your mobile phone and launch the program. Go to Options—>Settings—>Connection and change it to USB. Now go to the Options menu and click Connect.

5) Once AppTrk is connected, open “hack_perms_s60v3_FP1.py” with notepad on your PC. Search for search for “ser =” (without quotes) in the file. Change the default number 5 listed there to one less than the port number found in step (3). Save the file.

6) Now double click the “hack_perms_s60v3_FP1.py” file and wait until you see “!!!!!!!!!!!candidate!!!!!!!!!!!” on the command prompt. This indicates the hack was successful. You should have access to the C: drive using File Explorer.

7) If you want to turn on or off the hack directly on the mobile device without requiring access to a desktop computer, download this software. Using a file manager, copy the CProfDriver_SISX.ldd file into C:\sys\bin folder. Then install CapsOn and CapsOff one by one. Now whenever you want to enable the hack, select CapsOff and to disable it, like before a firmware upgrade, run CapsOn

8) You can then use Mobile Signer to self-sign applications without Open Signed and install them with full permissions by following the tutorial here.

In the next part, I will cover installing UnSigned applications with full access & permissions on Sony Ericsson UIQ based mobile devices.
