How to install unsigned applications on Symbian OS 9 based phones (3rd edition, UIQ) without symbiansigned

First of all you need to hack your Symbian OS 9 phone

Q.) How does this work?
A.) We’ll be adding our own authentication to the phone which will be used to authenticate the sis files signed by the certificate and the key provided. It will grant all the capabilities to the application including TCB!!

Note: This tutorial is same for all symbian OS 9 phones(n95,n82,n73,n8,P1i,w960i etc.) until’n’unless mentioned
So here’s the HOWTO for installing unsigned applications on your Symbian phone after you have hacked it(CapsOFF) :-

1. Download this rar file containing the certificate, the key and the authentication file for your phone. (Thanks to leftup of symbian freak)
2. Copy the file “00000001” to “C:\resource\swicertstore\dat\” on your phone and mark the file read-only from X-Plore or other similar file explorer. If the given directories do not exist , create them
3. So now your own authentication system is installed on your phone. Now you need to sign your sis files with the given certificate and key in the rar file.
4. For signing sis files (pc based method)(works for all Symbian OS 9 phones)
I) Download and install SignSis GUI on your PC
II) Select the given certificate and key(password is blank) given in ‘the rar file you downloaded’
III) Select the file you need to sign and sign it and transfer it to your phone, install normally
IV) Now you have the application installed with all its capabilities
4. Mobile based method(no need for a pc), works only for Nokia phones
I) Download and install MobileSigner on your phone
II) Open MobileSigner and select and sign the ‘unsigned sis file’ and MobileSigner will generate a signed sisx file in the same directory as the source file.
*if you have problem signing try “self-sign” option*
III) Install the generated sisx file and application will be having all its capabilities.

Enjoy!!! :)))

i too have the p1i…
1.)firstly have you turned capsswitch off

2.) are you able to explore c:/sys and private folder ??

if not this means your phone isn’t hacked or you may not have enabled the settings in x-plore to access those folder
check all the checkboxes in settings(press ALT->0->tick the first three boxes)

and now try making the folder again..

do post your results!
