Hacking S60 3rd edition firmware - Unlimited permissions for untrusted midlets

So, here's the hacking alternative - proceed at your own risk. By replacing some strings, we can give equals permissions to untrusted applications with the manufacturer signed applications.

First, update your S60 phone normally using Software Update tool from Nokia. It downloads updates to your harddrive, storing binary images to

C:\Documents and Settings\All Users\Application Data\Nokia\Nokia Service Layer\A\nsl_service_module_00001\www.dsut.online.n okia.com.oti.caresuite\Products\

Directory contents look interesting and for my phone there is about 50 MB rom image there. Simple strings scan on rom image shows contents some fragments of text based java permission file, which by closer look very interesting (at around 0x2310000 in my case) :

Now, all you need to do is to open up your favourite hex editor and write "MaximumMode: Blanket" to permissions you want to allow, and if you feel risky you can change the DefaultMode as well.

Now re-run the software update, force re-runing and phone will be flashed with your new permissions. After installing midlet, you should see more permission options in the application manager (select midlet, click open)...

TRICK to RECORD from VISUAL RADIO

100% WORKING


You must do the steps I write:

1. Install Ultimate Voice Recorder
2. Run Visual Radio via loudspeaker and set the biggest volume for best result
3. Run Ultimate Voice Recorder, for best result choose the wav format
4. Press record and set the biggest volume
5. Now you'll find it very easy to record audio from Visual Radio

Basically Ultimate Voice Recorder is great recording application which can record every sound, not only sound from Visual Radio or internet radio but every single sound that your phone emanates and sound comes around your phone. That's why, before recording make sure your surrounding is quite.
I don't know with another recorder, maybe they can record from radio too. I also attach a recorded files from Visual Radio in wav format as a sample.
Have a try! Hope that this will help people a lot.
