How to minimize Applications in Java devices ! Fast and easy tutorial 

So in today's tutorial i will teach you how to minimize Apps in Nokia s40 v3 , v4 , v5 . After successfully completing the tutorial you will be able to:-

• Hack into your phone's security system.
• Minimize Applications .
• Break app permissions .

The whole tutorial uses the J.A.F Software and some brain storming so here are the requires files :-

• J.A.F - Download HERE [With Instructions] , JAF is usually designed to Flash Java devices Firmware i.e the operating system they use , In flashing the original File system is removed and it is replaced by the new one in case a device is bricked or not functioning properly , but today we will use it for minimizing applications .

Follow the steps below to tweak your Firmware -

1. Connect your Nokia Java phone to your PC , via USB cable , in PC-Suite Mode .

• Execute the JAF Software , there you will find many tabs go to the BB5 Tab .
• After you click on BB5 tab there will be a list of few more options you have to tick the following one :-
• Read PP.
• Normal Mode .
• CRT 308 (In many devices it is already ticked). 

Then Click on the SERVICE TAB .

After you click that , you will get the 'PP' file , Save that .

After saving the file open it with wordpad or notepad etc.

• Now you have to Do a some CODE tweaking .
• In the pp file (after you open it in notepad etc) -
• For s40 v3 Models change the 28th Line from '1' to '2' , i.e From 28 1 to 28 2 .
• For s40 v5 and v 6 Models , you will have to change the 48th line from 1 to 2 , i.e from 48 1 to 48 2.
• In some devices , you will find that there's no 28th or 48th line , in that case you have to follow these steps -
• Just Below where it is written SET 1 Add the two lines i.e For s40 v3 add 28 2 , and for s40 v5 , v6 add 48 2 .

NOTE :- If your PP file shows only 3 fields , then just add 48 2 below set 1 and save your PP file .

• Now after the above is done , lets move to the next section .
• Go to JAF , again the BB5 Tab but this time click these options -
• Upload pp
• Normal mode CRT-308 .
• Click on service .
• Select the .pp file you just tweaked with .
• Most probably it will show DONE ! .
• Then from the Right Hand side 'Phone Mode' Drop down menu select 'Normal'.
• Your Device will restart and show the popup 'Test in RNDIS USB mode?' Press 'NO'... or you will brick your device .
• The phone will successfully reboot .

Now your phone's security is hacked . NOKIA SECURITY WALL>> GONE :D 

Modding the apps to work on your new Firmware :-

• Copy the requires Java app to your PC .
• Open it using any compression tool such as winrar , 7-zip etc .
• Search for Meta-Inf Folder , and open it .
• Open the Manifest.MF file in the meta-inf folder using notepad or any other editor .
• There you will find many codes , Just add the line below at the end of those codes :-

• Nokia-MIDlet-no-exit: True

Save the NOTEPAD File .
After that you will be asked to UPDATE the File , click on YES .

• Copy that .jar file to your Nokia and 'HAVE FUN'

To minimize the app , just click the RED 'Call end key' - it will not ask for any warnings but will minimize , to restore the app go to its original location and restore :)
